Onchange event in CMS

I'm trying to unobtrusively attach an onchange event to a select box on my CMS page. I've figured out that i can add custom script to a specific module using the augmentInit() function off the DataObjectDecorator.

What's confusing to me is that the window.onload() event seems to fire when the silverstripe logo comes up, which is before my select box is loaded into the DOM.

Anyone know how this is usually done?

Hi UncleCheese,

something like this is normally used:

   'select.domSelector' : {
      initialize: function () {
         // etc
      onclick: function() {

Not only will this get applied on page startup, but itll also be reapplied whenever a page is loaded using AJAX.

Perfect! What a great solution. So glad I posted here. I was sure no one would have an answer!
