jquery live event for added dom elements

Question

I want to add a class to any DOM element that is on the page now or in the future that has a specified class and meets some criteria

so for some pseudo code

Answer 1

jQuery's live() feature is just subset of the livequery plugin, which is much richer. If you use livequery you could do something like..

$('.location').livequery(function() {
   // perform selector on $(this) to apply class   
});

That will cover existing elements plus any future elements added to the DOM.
