Binding an event listener to a DOM element that may not yet exist

There's a very sweet jQuery plugin that makes it possible to bind event listeners to elements that may not have been added, yet, to the document. It's called livequery and I downloaded the 1.1.x version on github to work with my jQuery 1.3.2. (There's no 1.1.x version among the official releases on the jQuery site.) I used this plugin recently. The context was: another jQuery script was responsible for adding drop-down boxes to my web page. I wanted to do something on my end whenever a new selection was made in these drop-downs.

Just so that I remember... as a note to my future self... There's another way to bind an event to present and future elements, and that way relies on event bubbling:

jQuery(function() {
  jQuery('#myWrapperDiv').click(function(evt) {
    var targetedDOMElement =;
    if (jQuery(targetedDOMElement).is('#select-0 option')) {;
function doMyThing() {

I can bind an event to a container div element that exists already and which will contain my drop-down boxes. As a refresher, receives as first argument whatever we want the keyword this, in the function called, to refer to.

The way of the livequery plugin is less verbose somewhat. (Note: some functionality in livequery did make it to jQuery's 'core' but you can't listen to a change event with yet.)

This code does not need to be run when the DOM is ready:

jQuery('#select-0').livequery('change', function() {

Stunning site design by the way. The header with the cup is the prettiest thing I've seen on the web in a while.
