Fantastic, thanks Karl!
I didn’t realize their is an “each” function. That is so cool.
It worked.

No problem, Erik. Try this:

$('div.myclass').each(function() {
  $(this).children('p:lt(3)').addClass('newclass');
});

I'm sorry, my jquery actually is this: $('.myclass').children('p:lt(3)').addClass('newclass');

Karl,
I see you have been such a big help to everyone here! Thank you for that!

I have a small issue I’m trying to figure out. I apologize for the length of this comment in advance.
I want to add a class to the first 3 ‘p’ in my divs on a page. And there are never the same amount of “p”s in the divs.
The HTML looks something like this.

…

jquery I have so far is…
$('.naetext').children('p:lt(3)').addClass('newclass');

What this does is it adds a class of “newclass” to the first 3 “p”s consecutively and not the first 3 of each “set” of “p”s
So my HTML looks like this

added class 1

added class 2

added class 3

What I need is this…

added class 1

added class 2

added class 1

added class 2

added class 3

added class 1

added class 2

added class 3

Man, I hope that makes sense. I appreciate your time!

Sure, you could do something like this:

var childIds = [];
$('#mydiv').children().each(function() {
  childIds.push(this.id);
});

Or, you could use the .map() method:

var childIds = $('#mydiv').children().map(function() {
  return this.id;
}).get();

is it possible to get the id’s of all the children of an element and throw it into an array, or use it in a loop?
I am dynamically adding ‘a’ tags with unique id’s inside a div, and for each a tag I want to init a plugin like lightbox. I hope this makes sense…
