When I add something of the class "myClass" I want to call a function on this element.

It would be something in the lines of:

jQuery(".error_message").live("load",function(){
  alert("test"+this);
});

... except this doesn't exist.

What's the best way of doing this?

• How are you adding the elements to the DOM? – Colin Commented Sep 29, 2009 at 2:59
• I load a some new html via ajax and throw it in the DOM – marcgg Commented Sep 29, 2009 at 3:00
• There are different ways I could add these elements, that's why I'd like to avoid to have a callback on these functions. – marcgg Commented Sep 29, 2009 at 3:01
• This is something I've wanted to know for Greasemonkey scripts too... – Kip Commented Sep 29, 2009 at 3:04

1 Answer 1

The short, direct answer to your question would be "no can do." But from your comment a few minutes ago, I see that you want to add elements in different ways and have one unified method of handling these newly added items. May I suggest another approach? Trigger custom events.

The way it would work is like this: everywhere you load the error-message element, you add one line when it's done:

 $('.error_message').trigger('load');

Now your .live('load'...) thing will work.
