So in a sense, .delegate() can listen for new elements to be added to the Dom. What is the performance hit for always listening, if if there is even a hit at all?

Thank you for the post. I'm new with delegate and this helped much. Btw, the multiple delegate works now, see:


// WORKS NOW withoud plugin :-)
$('ul').delegate('li', {
  click: function(e){
    // Something on click
  },
  mouseover: function(e){
    // Something on mouse over
  }
});

You may update this. Kind regards Patrick

What Brandon is saying is that you’re missing the point of delegation. You never want to do $(“#container a”).delegate… delegation is attaching the events to the container, not the direct element. Also .delegate doesn’t break chainability as your comment on the final example says, as it always returns the right jQuery object, the one referencing the container. So this works:

$(“#container”)
.delegate(“p”,”click”,function(){})
.delegate(“a”,”click”,function(){});

hey thanks for this article.. i understand more about the difference..

one question. If you bind live directly to an id is it then better than delegate?

$(‘#idname’).live(click(function){

})

If you use live like this does it bubble also?
