jquery selector stops working after load()

in short, i have a page where the content is being loaded with jquery load(). the problem is when i am trying to select.

$('a.selected_class').click(function(e){
 alert('alert');
 e.preventDefault();
});

(inside document ready) works on the first page, but on any subsequent pages (that are loaded using $(this).load(url); into a div), the selector stops working.

any tips?

click() only will work on elements that exist on the page currently. Check out live and delegate. With live:

$('a.selected_class').live("click", function(e){
 alert('alert');
 e.preventDefault();
});

As patrick dw mentions, delegate is preferred if possible.

It isn't that it stops working. It is that it only binds click handlers to those elements that exist when it runs (on page load).

You can place a .delegate() handler on the <div> that the dynamic ones are loaded into.

$('#mydiv').delegate('a.selected_class','click',function(e){
   alert('alert');
   e.preventDefault();
});

The handler is placed on the #mydiv element, and when the click event bubbles up to it, it tests to see if the event took place on an element that matches a.selected_class.

The .live() method does the same thing, but it does it for the entire document, so it normally isn't an advisable method to use.
