Hmm this is an interesting idea, so many different ways to access that
property, and with no native property change model it seems
impossible. My first thought was using a timer but that is going to
gum up resources. If in your app you were savvy and used a setter
method you could implement an event that would get this done. Using
prototype's setStyle, and ele being a valid dom reference you could do
something like this
ele.setStyle = ele.setStyle.wrap(function(prc, style){
if(style.height && this.getHeight() != style.height.match(/^[0-9]+/
g).first()){
prc(style);
this.fire("derka:heightChange");
}
else
prc(style);
});
Which would work fine for a single element, if you wanted to observe
multiple elements height change I'd suggest iterating over a
collection of objects that needed this functionality and wrap their
setStyle methods.
Here is a basic working demo of this in action, be sure to have
firebug working as the debug comes across in the console.
