When it comes to creating a website, mobile application, or desktop software, developers have to ensure that the latest development trends and technologies are factored in in the development process. This is especially the case when building the front-end of any digital product.

And talking about front-end development, jQuery is one of the leading JavaScript libraries for front-end development, thanks to its neat syntax, ease of use, and cross-browser compatibility. jQuery works by compressing multiple lines of JavaScript codes into a single line of code, making HTML document manipulation and traversal, animation, and event handling much simpler.

But despite jQuery being used by over 43% of developers including when building CSGO coinflip
websites, there has been a persistent shortage of jQuery skills the world over, if the number published by EvansData are anything to go by.

But all is not doom and gloom. If you are an inexperienced programmer looking to make a career out of jQuery or simply looking to branch into the library and interactive programming, there are plenty of resources to learn from.

In this article, we have curated a list of the top 8 books about jQuery everyone should read.

  • Introducing HTML5

HTML5 is constantly evolving, and so does its uptake by different browsers and HTML5 websites. If you’re an upcoming programmer looking to explore the possibilities of HTML5, its merits and demerits, as well as the aspects that are yet to be adopted, this book by Bruce Lawson and Remy Sharp will serve as an excellent guide.

Other important elements covered in the book include;

  • How to apply JavaScript APIs.
  • How to use and control native
    multimedia
  • The best methods to create more intelligent web forms.
  • Details on geolocation, canvas, and offline storage options.
  • JQuery in 8 Hour, For Beginners, Learn JQuery fast!
  • As the name suggests, this book is intended to teach all the JQuery basics in a record 8 hours. Specifically designed for beginners, it covers all the essential JQuery knowledge, and it is laid out in simple, plain language, making it fast and easy to understand.

    Under the hood, you will find 80+ practical examples to study and over 100 questions & answers to help beginners with different aspects of jQuery. Other notable mentions inside the book include JQuery Function, Elements Selection, Functions, Events, Effects & Animation, Utility Functions, and Ajax by JQuery.

  • jQuery Cookbook

Picture this… 19 highly experienced programmers coming together to develop a guidebook with the most practical jQuery tips and techniques.  And that’s exactly what jQuery cookbook does. Using the experience that they’ve gathered throughout the years, the authors of the book cover even the smallest nuggets you’d ever want to know about the JavaScript library, as well as how to implement them.

But that’s not the best part. The book follows a chronological delivery pattern, which covers the basics first and gradually gets complex as the reader delves deeper into the topics. Still, there are practical scenarios planted all over the book, making it easy to practice what you’ve learned.

  • Head First jQuery

Ryan Benedetti is one of the most established and widely-published web developers in the world.  In his Head First jQuery, Ryan is basically trying to take you through all the aspects of the jQuery library in improving frontend programming. Although still ideal for beginners, the book is much more ideal for experienced web developers and owners aiming to spruce up the user-side elements of their websites.

Key among other topics covered in Head First jQuery include:

  • Navigating HTML documents.
  • Using jQuery functional to
    create visual effects and animations, building forms, and handling
    different events, etc.
  • Writing productive AJAX apps.
  • Leveraging the power of CSS and HTML.
  • Manipulate given data using MySQL, JSON, and PHP.
  • Learn JavaScript VISUALLY

Looking to learn your way up the ropes on the basics of JavaScript in a more visual fashion? Learn JavaScript VISUALLY is your go-to book. It covers both basic and deep JS concepts and topics mainly using pictures making it easier to grasp.

  • Effective JavaScript: 68

What Is jQuery .css() Method?

HTML, CSS, and JavaScript are the three primary pillars in designing the structure of any website. When it comes to the designing part CSS plays the most significant role, providing various styles for developing your website. Vardenafil http://valleyofthesunpharmacy.com/levitra

It is the style sheet that adds the visual elements of any webpage. Thus, the .css() method in jQuery is used to set or return the style properties of the elements.

What Does jQuery .css() Do?

jQuery is widely used in designing a website. The jQuery .css() method is used to assign or return style properties for the selected elements. It returns the specified CSS property value of only the first matched element.

Whereas the .css() method sets the specified CSS property for all the matched elements.

The .css() method is the most basic and easy to implement in jQuery. It can assign one or multiple CSS properties and values at a time.

How Does jQuery .css() Work?

The jQuery .css() method is used to assign various styling properties for designing a website. It can assign properties using single or multiple values as well as using a function. Xanax online http://www.healthfirstpharmacy.net/xanax.html

jQuery .css() also returns the single property value of the element.

Syntax:

Returns the CSS
Property Value:

$(selector).css(property)

Set the Single
CSS Property and Value:

$(selector).css(property,value)

Set CSS
Property and Value using a Function:

$(selector).css(property,function(index,currentvalue))

Set Multiple
CSS Properties and Values:

$(selector).css({property:value,property:value, ...})

Here the “property” specifies the name of the property e.g: color, font-size, etc and the “value” specifies the value of the property e.g: red, 20px, etc.

Also, the “function” specifies the function that returns the value for the CSS property, “index” returns the index position of the element, and the “currentvalue” returns the current value of the property. 

Example:

A simple example to set text color as red using .css() method.

<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
 
$("button").click(function(){
   
$("p").css("color", "red");
  });
});
</script>
</head>
<body>
 
<button>Set Font-color as Red</button>
<h1>
<p>Example for .css() Method.</p>
<p>Text 1</p>
<p>Text 2</p>
</h1>
</body>
</html>

What Is jQuery .css() Method?

What Are The Ways To Use Properties With The .css() Method?

There are three ways to use CSS property:

  1. Return CSS Property Value
  2. Set CSS Property and Value using a Function
  3. Set Multiple CSS Properties and Values

1. Return CSS Property Value

You can return the specified CSS property value of the element that has
matched.

Example:

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>css demo</title>
  <style>
  div {
    height: 50px;
    margin: 5px;
    padding: 5px;
    float: left;
  }
  #box1 {
    width: 150px;
    color: yellow;
    background-color: blue;
  }
  </style>
  <script src="https://code.jquery.com/jquery-3.5.0.js"></script>
</head>
<body>
<p id="result">&nbsp;</p>
<div id="box1">Click Here To Get Values</div>
<script>
$( "div" ).click(function() {
  var html = [ "The CSS Property Value:" ];
 
  var styleProps = $( this ).css([
    "width", "height", "color", "background-color"
  ]);
  $.each( styleProps, function( prop, value ) {
    html.push( prop + ": " + value );
  });
 
  $( "#result" ).html( html.join( "<br>" ) );
});
</script>
</body>
</html>

2. Set
CSS Property and Value using a Function

With this
method, you can assign the CSS property and value using a function.

Example:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
 
$("button").click(function(){
   
$("p").css("border-width", function(i){
      return i + 50;
    });
  });
});
</script>

3.Set multiple CSS Properties and Values

You can assign
multiple CSS properties and values for selected elements. Here is an example to
assign multiple CSS property and value on <p> elements.

Example:

<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
 
$("button").click(function(){
   
$("p").css({
     
"color": "white",
     
"background-color": "red",
     
"font-family": "Times New Roman",
     
"font-size": "30px",
     
"padding": "10px"
    });
  });
});
</script>
</head>
<body>
<h1>Set Multiple CSS Properties and Values</h1>
<button>Set CSS Properties</button>
<p>Example to Set Multiple CSS Properties And Values</p>
</body>
</html>

What Are jQuery Events?

jQuery is the most used JavaScript library for designing web pages. It provides different functions, events, effects, and animation for effective web designing.

jQuery events are various visitor’s actions that a web page can respond to. It is a function that triggers user action. jQuery event has various methods like click, keypress, mouse events, and much more.

All these events contain some action e.g clicking on an element or moving a mouse over an element, etc.

What Does jQuery Events Do?

jQuery events have various types of methods like Mouse Events which include click, dblclick (double click), mouseenter, and mouseleave. It also has different Keyboard Events, Form Events, Custom Event, and Windows Event. Generic Cialis http://www.wolfesimonmedicalassociates.com/cialis/

These events respond to different user actions on web pages. Thus it helps you in creating a responsive web design for your website. Most DOM events in jQuery have equal jQuery methods.

How To Use The jQuery Events?

jQuery Events are easy to define and execute in your HTML code. You just have to follow two steps:

To assign an event to elements on a page, follow syntax:

$("element").event_name();

E.g : $("button").click(); 

This will assign a click event on all <button> elements.

The next step is to define what action should perform when the event occurs. We need to pass a function to the event.

Syntax:

$("element").event_name(function(){// action});

E.g: $("button").click(function(){// Submit});

jQuery Events are defined within the <script> tag of your HTML file.

Let us see an example using the jQuery “keypress” event to count the number of times the key is pressed on the keyboard. Phentermine 37.5 online http://kendallpharmacy.com/phentermine.html

Code:

<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
i = 0;
$(document).ready(function(){
  $("input").keypress(function(){
    $("span").text(i += 1);
  });
});
</script>
</head>
<body>
<h1>Example to use jQuery "keypress" event</h1>
<h2 style="color:blue">
Enter Text: <input type="text" style="font-size:24px">
<p>Keypress Count: <span>0</span></p>
</h2>
</body>
</html>

Here's how output will be:

What Are jQuery Events?

What Are The Various jQuery Event Methods?

jQuery provides a variety of event methods to perform various actions and design responsive web pages. These event methods include various Keypress Events, Mouse Events, Form Events, and Windows Events. Some of them are:

1.The dblclick() Event:

This is a mouse event that triggers when an element is double-clicked. 

Syntax:

$(selector).dblclick(function)

Here the “function” specifies the action to be performed when double-click event occurs.

E.g :

$("button").dblclick(function(){
          alert("The button was double-clicked");
          });

2.The resize() Event:

It is a windows event that is triggered when the browser window changes its size. You can count the number of times the size is changed.

Syntax:

$(selector).resize(function)

E.g:

$(window).resize(function(){
           $('span').text(x += 1);
         });

3.The submit() Event:

This event triggers when a form is submitted. It is used with <form> elements to perform submit action.

Syntax:

$(selector).submit(function)

E.g:

$("form").submit(function(){
        alert("Form Submitted Successfully!!");
        });

4.The mouseenter() Event:

It is a mouse event that triggers when the mouse pointer enters the selected elements.

Syntax:

$(selector).mouseenter(function)

E.g:

$("button").mouseenter(function(){
           $("button").css("background-color", "blue");
         });

5.The keyup() Event:

It is a keypress event that is triggered when a keyboard key is released.

Syntax:

$(selector).keyup(function) 

E.g:

$("input").keyup(function(){
            $("input").css("background-color", "red");
         });

Let us see an example to implement the “click” event on all <p> elements.

Code:

<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
  $("p").click(function(){
    $(this).hide();
  });
});
</script>
</head>
<body>
<h1>Example to use jQuery "click" Event</h1>
<h2 style="color:red">
<p>I will not be seen if you click on me!</p>
</h2>
</body>
</html>

Here's how output will be:

jQuery AJAX

AJAX stands for Asynchronous JavaScript and XML. jQuery AJAX is used to store the data in the background and display it on your web pages, without actually reloading the entire web page.

The jQuery AJAX methods let you request text, HTML, XML, or JSON from a remote server. jQuery AJAX has various methods to perform various actions on web pages like get, post, param, ajax, and much more.

What Does jQuery AJAX Do?

The main function of the jQuery AJAX method is to load and display data on your web pages without reloading it. jQuery AJAX can perform various actions on your web pages like load, get, post, ajax, start, stop, send, error, etc using various AJAX methods.

It allows you to load external data from the server into the selected HTML elements directly. Thus jQuery AJAX helps you develop faster, amazing, and interactive web pages for your website.

How To Use jQuery AJAX?

jQuery AJAX methods are very easy to implement. They are written within the <script> tag in your HTML file. Here is the syntax for jQuery AJAX:

Syntax: 

$.methodname({name:value, name:value, ... })

Example:

For .ajax()
method the syntax will be:

$.ajax({name:value,name:value, ... })

Let us see an
example to implement the ajax() method using the jQuery AJAX method to change
the text.

Code:

<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
  $("button").click(function(){
    $.ajax({url: "test_ajax.txt", success: function(result){
      $("#test").html(result);
    }});
  });
});
</script>
</head>
<body>
 
<div id="test"><h2>Example to implement jQuery .ajax() method</h2></div>
 
<button>Click Me!</button>
 
</body>
</html>       

Here's how the output will be:

Before clicking the button

jQuery AJAX

After clicking the button

jQuery AJAX

The text is changed when you click the Click Me button. This is done using the .ajax() method.

What Are The Various jQuery AJAX Methods?

jQuery provides a variety of AJAX methods to load data from the server into webpages. Some of the important ones are listed below:

1.The .get() method:

The .get() method is used to load data using an HTTP GET request from the server.

Syntax:

$.get(URL,data,function(data,status,xhr),dataType)

Here ”URL” specifies the URL you want to request, “data” specifies data to send to the server, “function” is used to specify a function to run along with data, status, and xhr which contains data, status, and XMLHttpRequest object. The “dataType” contains the data type expected of the server response.

2.The .post() method:

The .post() method is used to load data using an HTTP POST request from the server.

Syntax:

$(selector).post(URL,data,function(data,status,xhr),dataType)

3.The load() method:

The load() method is used to load data from a server. It puts the data that is returned into the selected element.

Syntax:

$(selector).load(url,data,function(response,status,xhr))

4.The .getJSON() method:

The .getJSON() method gets JSON data using an AJAX HTTP GET request.

Syntax:

$(selector).getJSON(url,data,success(data,status,xhr))

5.The ajaxSetup() method:

For future AJAX requests, the ajaxSetup() method sets the default values.

Syntax:

$.ajaxSetup({name:value, name:value, ... })

Let us see an example to use jQuery AJAX .serialize() method to get the serialize values from form. For this, we will add a form to the web page where the user will input the values. . We will also add a button with the click function to fetch the values entered by the user. These values will then be serialize using the .seralize method().

Code:

<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
  $("button").click(function(){
   
$("div").text($("form").serialize());
  });
});
</script>
</head>
<body>
 
<form action="" style="font-size:24px">
  Name: <input type="text" name="Name" value="John" style="font-size:20px"><br><br>
  Roll No: <input type="text" name="RollNo" value="10" style="font-size:20px"><br><br>
</form>
 
<button>Click here to serialize values</button><br><br>
 
<div></div>
 
</body>
</html>

Here's the output will be for the above code:

jQuery AJAX

Conclusion

In this tutorial, we learned what is jQuery AJAX and various jQuery AJAX methods. We also learned how to use various jQuery methods. In the above examples, we implemented the jQuery AJAX .ajax() method to change the content and the jQuery AJAX .serialize() method to get the serialize values from form.

What Are jQuery Selectors?

jQuery is the most popular and widely used Javascript library that lets you simplify traversal and manipulate the HTML DOM tree. It offers you easy access to elements or group of elements in the DOM. The official website of jQuery calls it a powerful tool.

When you want to select or manipulate one or more than one HTML element, jQuery selectors are used. It lets you find out matching elements from DOM using expressions. It is interesting to note that jQuery selectors are linked to CSS selectors.

There are multiple selectors based on element, id, class, types, attributes, and many more.

What Does jQuery Selectors Do?

jQuery selectors play a very significant role in the JavaScript library. They are basically functions that allow you to select elements based on the given criteria from DOM.

These unique selectors are used to find and manipulate HTML elements based on various attributes or attribute values like name, id, class, HTML tags, etc.

Thus making it easier for you to find and access elements from DOM.

How To Use The jQuery Selectors?

It is very easy to use jQuery selectors. They are written within the <script> tag. All the jQuery selectors start with a dollar sign and contain attributes within the parentheses: $(). Let us take a look at the syntax and then discuss an example using the "this" selector.

Syntax:

$(attribute)

Example:

 $(*)

Let us see how to hide the current element using the “this” selector.

Code:

<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
  $("button").click(function(){
    $(this).hide();
  });
});
</script>
</head>
<body>
<h2>Example to use jQuery selector using "this" Selector</h2>
<p>"this" selector selects the current HTML element.</p>
<button>Hide me</button>
</body>
</html>

You can explore more examples on your own at CodePen. From the code, you know what the output will be. Let's take a look:

What Are Various jQuery Selectors?

jQuery selectors provide multiple ways to select and manipulate elements. Here are some important jQuery selectors that can be helpful to a web developer:

1.The #id
Selector:

It uses the attribute “id” of the HTML tag to select
elements.

Syntax: $("#id_name")

2.The .class
Selector:

It selects elements with a specific class.

Syntax: $(".class_name")

3.The “*”
Selector:

This selector is used to select all the elements.

Syntax: 
$("*")

4.The “this”
Selector:

This selector is used to select the current element in HTML.

Syntax:  $(this)

5.The “p:first”
Selector:

It is used to select first element in <p> tag.

Syntax: 
$("p:first")

6.The “p:test”
Selector:

It is used to select all elements in <p> tag with
class=”test”.

Syntax: 
$("p.test")

7.The “:button”
Selector:

It selects all <button> elements as well as
<input> elements of type="button"

Syntax:  $(":button")       

8.The “tr:odd”
Selector:

It is used to select all odd <tr> elements.

Syntax: 
$("tr:odd")

9.The “tr:even”
Selector:

This selector is used to select all even <tr>
elements.

Syntax: 
$("tr:even")

10.The “[href]”
Selector:

It is used to select all elements with attribute “href”.

Syntax: 
$("[href]")

11.The "ul
li:first" Selector:

It selects the first <li> element of the first
<ul> tag.

Syntax: $("ul li:first")

12.The
"a[target='_blank']" Selector:

This selector selects all <a> elements with an
attribute value equal to "_blank"

Syntax: $("a[target='_blank']")

Let us see an example to select even <tr> elements in
a table using jQuery “tr:even” selector.

Code:

<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
 
$("tr:even").css("background-color", "lightblue");
});
</script>
</head>
<body>
 
<h1>Example to use "tr:even" selector in jQuery</h1>
 
<table border="1">
  <tr>
    <th>Product</th>
    <th>Id</th>
  </tr>
  <tr>
    <td>Book</td>
    <td>1001</td>
  </tr>
  <tr>
    <td>Pen</td>
    <td>1002</td>
  </tr>
  <tr>
    <td>Scale</td>
    <td>1003</td>
  </tr>
  <tr>
    <td>Pencil</td>
    <td>1004</td>
  </tr>
  <tr>
    <td>Bag</td>
    <td>1005</td>
  </tr>
</table>
 
</body>
</html>

Here's how the output will be:

What Is jQuery Migrate?

jQuery as we already know is an in-built library containing JavaScript functions. It is a JavaScript file that you link to your HTML file. It is used to simplify a lot of complicated things from your JavaScript file.

jQuery is such a huge library that it may require a lot of work to upgrade it. This is where jQuery migrate comes into the picture. It is used to reduce the efforts to upgrade different jQuery versions and makes the task easier and quicker.

What Does jQuery Migrate Do?

It is very difficult to upgrade jQuery especially when many new features have been added. When you introduce new features on top of older ones your code becomes messy. To avoid this jQuery migrate is the best solution.

jQuery migrate adds back the APIs that have been eliminated, and additionally shows errors or feedbacks in the browser (development version of jQuery Migrate only) when the user uses APIs that have been eliminated. Thus making it easier to upgrade jQuery without affecting our code.

jQuery migrate lets your code be compatible especially if it has been written with any versions older than 1.9.

How To Use The jQuery Migrate Plugin?

It is very easy
to use migrate plugin in your HTML code.

In your web page, load the migrate plugin in the <script> tag after the <script> tag for jQuery.

<script src="https://code.jquery.com/jquery-3.4.1.js"></script>
<script src="https://code.jquery.com/jquery-migrate-3.4.2.js"></script>

Example: A simple code to implement jQuery migrate in your HTML file.

<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js">
<script src="https://code.jquery.com/jquery-migrate-3.5.1.js"></script>
</script>
<script>
$(document).ready(function(){
 
$("button").click(function(){
   
$("p").css({"color": "red"});
  });
});
</script>
</head>
<body>
<h2>
<p>Example To Implement jQuery Migrate</p>
<h2>
<button>Set Text Color To Red</button>
 
</body>
</html>

What Is jQuery Migrate?

What Are The Types Of Migrate Plugin APIs?

Migrate plugin APIs are used to add some properties to the jQuery object. It is used to programmatically control and examine the behavior of jQuery object. There are six jQuery migrate plugin APIs:

1.jQuery.migrateWarnings

With the help of this property, you can print multiple warning messages that have been triggered on the page by your code. The order remains the same as printing the messages like that of the generation of messages. The messages will be printed only one time in the series even if the condition has been triggered more than once. 

Example:

if ( jQuery.migrateWarnings ) {
                       window.console.log( "Migrate plugin loaded multiple times" );
           }

This will print warning
messages at the console.

2.jQuery.migrateMute

When you set jQuery.migrateMute to “true” it mutes the warning messages. Thus, the warnings will not be generated.

jQuery.migrateMute =
true;

Even if this property is set to true, jQuery.migrateWarnings succeeds it and thus you can inspect the warnings without generating them.

3.jQuery.migrateTrace

Sometimes, you may want the messages to be shown on the console of the browser but you would not want stack traces to be shown. You can do this by setting jQuery.migrateTrace to false.

Example:

if (
jQuery.migrateTrace === undefined ) {

     
     jQuery.migrateTrace = true;

}

4.jQuery.migrateReset()

As the name says, jQuery.migrateReset() resets the array. This property is used to clear the jQuery.migrateWarnings array.

Example:

jQuery.migrateReset =
function() {

     
     warnedAbout = {};

     
     jQuery.migrateWarnings.length = 0;

};

5.jQuery.migrateVersion

This property is used to show the version of Migrate that is currently being used.

Example:

window.console.log(
"Migrate installed" + ", version " + jQuery.migrateVersion
);

This will print the
current installed version of migrate.

6.jQuery.migrateDuplicateWarnings

As discussed above, migrate only generates a warning message once even if the condition is triggered many times. You can set jQuery.migrateDeduplicateWarnings to false to get warning messages every time a condition is triggered. But this can be inefficient especially if a loop of warning is triggered.

jQuery.migrateDeduplicateWarnings
= false;

Conclusion

In this tutorial, we learned what is jQuery and how it can be useful to upgrade jQuery to different versions. We also saw the types of migrate APIs, their syntax, and how they can be used. jQuery migrate is one of the APIs that truly make jQuery helpful to web developers.

What Are jQuery Effects?

jQuery is the most used JavaScript library for designing a variety of web pages. Designing web pages not only includes content and styles but also various effects and animations to make it attractive.

In order to design effective web pages for your website, jQuery provides various effects and animations. It easily adds various effects and animations to your web pages just within a few steps.

In this tutorial, we will learn what jQuery effects do and the different types of effects that can be added using jQuery functions. Some of the effects we will learn today are Hide/Show effect, fadeIn and fadeOut effects and some others.

Let's dive in to the topic!

What Does jQuery Effects Do?

jQuery Effects are like the cherry on the cake in designing web pages. It adds effectiveness and helps to easily create web pages with various effects and animations.

You can add various effects like hide/show, fade, slide, animate, toggle, and much more. jQuery allows you to add simple, standard effects that are commonly used, and the ability to create new custom effects.

How To Use The jQuery Effects?

You can quickly
add jQuery effects and animations to your HTML code. The effects are added by including
jQuery effect methods into your <script> tag.

Let us see an
example to use the jQuery Hide/Show Effect. Here when you will click on the
“Hide” button the text will disappear and when you click on the “Show” button
the text will appear again. 

Code:

<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
 
$("#hide").click(function(){
   
$("p").hide();
  });
 
$("#show").click(function(){
   
$("p").show();
  });
});
</script>
</head>
<body>
<h1>Example To Use jQuery Hide/Show Effect</h1>
<p>Try Me!</p>
 
<button id="hide" style="background-color: lightblue">Hide</button>
<button id="show" style="background-color: lightblue">Show</button>
 
</body>
</html>

You can see the hide and show effect in the output below:

What Are jQuery Effects?

What Are The Various jQuery Effect Methods?

jQuery provides a lot of standard effect methods to design beautiful web pages. Learning these effects can can be really helpful for a web developer to create interactive web pages. Some of the methods are as follows:

1.animate()

It is used to
run custom animations on the selected elements.

Syntax: (selector).animate({styles},speed,easing,callback

Here “styles”
specifies one or more CSS values to animate, “speed” specifies the speed of to animate,
“easing” also determines speed but at different points in animation, and
“callback” is to be executed after the animation completes.

2.delay()         

This method is
used to delay the execution of all queued functions on the selected elements.

Syntax: $(selector).delay(speed,queueName

Here
“queueName” specifies the name of the queue.

3.fadeIn()       

It is used to
fade in the selected elements.

Syntax: $(selector).fadeIn()

4.fadeOut()    

It is used to
fade out the selected elements.

Syntax: $(selector).fadeOut()

5.hide()           

This method is
used to hide the selected elements.

Syntax: $(selector).hide()

6.show()         

This method is
used to show the selected elements.

Syntax: $(selector).show()

7.slideUp()      

It is used to
slide-up or hide the selected elements.

Syntax: $(selector).slideUp()

8.stop()           

This method
stops the currently running effect or animation for the selected elements.

Syntax: $(selector).stop()

9.toggle()       

It toggles
between the hide() and show() methods.

Syntax: $(selector).toggle()

Let us see an
example using the fadeIn Effect. Here when you will click on the button the
content will fade.

Code:

<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
 
$("button").click(function(){
    $("#box1").fadeIn();
   
$("#box2").fadeIn("slow");
   
$("#box3").fadeIn(3000);
  });
});
</script>
</head>
<body>
 
<h1>Example To Use jQuery fadeIn Effect</h1>
<button>Click Me to fadeIn Content</button><br><br>
 
<div id="box1" style="width:90px;height:50px;display:none;background-color: lightblue;"><h2>jQuery</h2></div><br>
 
<div id="box2" style="width:90px;height:50px;display:none;background-color:lightblue;"><h2>fadeIn</h2></div><br>
 
<div id="box3" style="width:90px;height:50px;display:none;background-color: lightblue;"><h2>Effect</h2></div>
</body>
</html>

Here's how the output will be:

What Is jQuery append()?

jQuery is an easy-to-use open-source JavaScript library. jQuery provides various methods to add interactive functionalities into your website which makes it unique from other JavaScript libraries. The jQuery append() method is used to append text or content specified by the parameter to the end of each element in the set of matched elements.

What Does jQuery append() Do?

The jQuery append() method appends or inserts the specified content as the last child by the parameter, to the end of each element in the set of matched elements. The .append() and .appendTo() methods performs the same task. The only difference is that with the append() method the selector expression preceding the method is the container into which the content is appended while in the appendTo() method the content precedes the method, either as a selector expression or as markup created, and it is appended into the target container.

How Does jQuery append() Work?

The jQuery append() is used to insert the content at the end of the selected elements.

The syntax of append() is as follows:

$(selector).append(content,function(index,html))

OR  $(selector).append( content [, content ] [,
content ] [, content ]..... )

The “content” specifies the content to append or insert. The “function” specifies a function that returns the content to insert where “index” returns the index position of the element in the set and “Html” returns the current HTML of the selected element.

You can append any number of content within a single append statement. You can create several new elements with HTML, Text, Array, jQuery, and DOM. And then you can append these elements to the text using the append() method.

Let's take a simple example to append text on the list.

html>
  <head>
    <script 
    src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"> 
    </script>
    <script>
      $(document).ready(function(){
      $("#btn2").click(function(){
      $("ol").append("<li>Text New(Appended Text)</li>");
    });
    });
    </script>
  </head>
  <body>
    <h2>
    <p>Example to Append Text using .append() Method</p>
    </h2>
    <ol>
    <li>Text 1</li>
    <li>Text 2</li>
    <li>Text 3</li>
    </ol>
    <button id="butn2">Append Text</button>
  </body>
</html>

This is what the output for the above code will be. You can explore it some more on your own using CodePen.

What Is jQuery append()?

What Are The Ways To Append Elements Using The append() Method?

There are two ways to insert an element using the append() method:

  1. Append content using the append() method
  2. Append content using a function

1.Append Content using the append() method:

In this method, you can create content using HTML, Text, Array, jQuery, and DOM and append it by defining elements directly inside the append() method.

Let's take a short example to understand how this method works:

<!DOCTYPE html>
<html>
  <head>
   <script 
    src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"> 
    </script>
    <script>
    function appendText() {
    var txt1 = "<p>Text1</p>";        // Create text with HTML
    var txt2 = $("<p></p>").text("Text2");  // Create text with jQuery
    var txt3 = document.createElement("p");
    txt3.innerHTML = "Text3";         // Create text with DOM
    $("body").append(txt1, txt2, txt3);   // Append new elements
    }
    </script>
  </head>
  <body>
    <h2>
    <p>Append Content Using .append() Method </p>
    </h2>
    <button onclick="appendText()">Append Text</button>
  </body>
</html>

Here's how the output will look for the above code:

2.Append content using a function

This method is used to append a text or content using a function defined inside the <script> tag. It returns the content to append at the end of each element in the set of matched elements.

Let's take an example:

<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
 
$("button").click(function(){
   
$("p").append(function(n){
      return "<b>Appened Text " + n + ".</b>";
    });
  });
});
</script>
</head>
<body>
 
<h1>Append Content Using Function</h1>
 <p>This is </p>
<p>This is </p> 
<button>Insert Content at the end of each "p" element</button>
</body>
</html>

This is what the output will be:

What Is jQuery append()?

Conclusion

In this tutorial, we learned how to use jQuery append(). We saw how it can be very helpful to append content or text. We also saw some of the different ways to use jQuery append(). It is interesting to know that jQuery also has a function called appendTo() in its library. Even though these are similar functions, they have a difference between, especially in their syntax.

How To Add jQuery To HTML?

HTML, CSS, and JavaScript are the three fundamental languages for designing any website. We structure our websites with HTML code, style them with CSS, and add various functionalities with the help of JavaScript.

jQuery is a widely used JavaScript library. With the help of an easy-to-use API that works across a multitude of browsers, jQuery makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler and easier. It simplifies client-side scripting of HTML.

Where To Put jQuery In HTML?

jQuery lets you perform actions in less code as compared to JavaScript. It is quite popular among the developers because of its simplicity, compatibility, flexibility, amazing effects, and ease in adding code to the HTML file. jQuery is embedded into the <script> tag of HTML file between the <head> tag and the <title> tag.

How To Include jQuery In HTML?

Including jQuery to HTML is one of the easiest tasks. It is very simple to include jQuery into the HTML page within just a few lines of code and hence it is widely used by web developers.

There are two methods to include jQuery to your HTML.

  • You can download and include the jQuery file

  • You can include the jQuery by CDN.

  1. Download and include jQuery file

In this method, you have to download the jQuery js file and include it using a simple <script > tag within your HTML code. It is very easy for any user to add jQuery to Html within just a few steps. If you want to include the jQuery to your HTML page by downloading the jQuery file, simply follow the steps given below. 

Step
1: You have to download the jquery js file from the official site of jQuery. 

https://jquery.com/download/

How To Add jQuery To HTML?

Step 2:  After downloading the file you have to open the Html file in which you want to add your jQuery. In your HTML code have to use the <script> tag, which specifies the src attribute for adding the jQuery file between the head tag just and the title tag as shown below:

<script type="text/javascript" src="jquery-3.5.1.min.js"> </script> 

Step 3:  And finally save your HTML file and you can see that the jQuery file is successfully added into our Html page.

Let's understand with an example:

<!Doctype Html>  
<Html>    
  <Head>     
    <script type="text/javascript" src="jquery-3.5.1.min.js">  
    </script> 
    <Title>    
    Add the jQuery file into Html  
    </Title> 
  </Head> 
  <Body>  
    <h1>
    Adding the jQuery file into your HTML Page by Downloading and Including 
    file <br> 
    </h1>
  </Body>  
</Html>

Here's what the output will be:

How To Add jQuery To HTML?

2. Including the jQuery by CDN. 

Another method to include your jQuery to Html is including the jQuery by CDN(Content Delivery Network). It is very easy to implement by using CDN using the following steps.

Step 1: Open the HTML file in which you want to add your jQuery with the help of CDN.

Step 2: Add <script> tag between the head tag and the title tag which will specify the src attribute for adding your jQuery.

<script type="text/javascript" src=> </script>

Step 3: After that, you have to add the following path in the src attribute of the script tag.

http://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js

Step 4: Save your HTML file and your jQuery is successfully added.

Let's see how this is done:

<!Doctype Html>  
<Html>    
  <Head>   
    <script type="text/javascript" 
    src="http://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js">  
    </script> 
    <Title>    
    Including the jQuery by CDN  
    </Title> 
  </Head> 
  <Body>  
    <h1>
    Adding the jQuery File into HTML by Including CDN
    </h1>  
  </Body>  
</Html> 

How To Add jQuery To HTML?

Conclusion

In this tutorial, we learned how to add jQuery to HTML. We saw two different ways of doing it. The first one is by adding a jQuery file and the second is by CDN. Javascript and HTML are two integral parts of modern web development. Since jQuery is just a Javascript library it becomes important for any web developer to learn how to add jQuery to HTML.
