The thing is that Field builder has its field, and in this case “load”
event means that field builder is loaded, with the fields, but fields are not loaded by itself.
In case of Keyword field, it uses XSLT transformation to render field view.
Unfortunately Keyword select control does not fire any events which might help in this case. Thus I would suggest to extend _onItemDraw
method from \WebUI\Editors\CME\Controls\KeywordSelect\KeywordSelectControl.js
Eric gave a good reply on how it can be possibly done in a similar post: http://tridion.stackexchange.com/a/1856/206
The extended code will look like:
(function ()
{
var overridenKeywordSelectControl$_onItemDraw = Tridion.Controls.KeywordSelectControl.prototype._onItemDraw;
Tridion.Controls.KeywordSelectControl.prototype._onItemDraw = function KeywordSelectControl$_onItemDraw()
{
// Call original method
overridenKeywordSelectControl$_onItemDraw.apply(this);
// Do an action you need
var element = this.properties.container;
console.log(element.innerHTML);
// Or fire event which you can handle elsewhere
this.fireEvent("extension_oncontroldrawn");
};
})();
