I want that as you type in the textfield the div changes (I have the code for changing the div already). However the onchange event is only called once you are finished and
There is an 'input' Event you can bind your event Handlers to (I think this was introduced with HTML5).
I made a quick and very dirty example here: http://jsfiddle.net/RdKZH/
This would be the clean approach to this problem (as keyup does not work on copy&paste), but you might want to test if it already works in all browsers you want to support.
