javascript - Listening to events of a contenteditable HTML element

Question

I'm trying to figure out if there is any way to listen to events like focus or change of an HTML element with contenteditable attribute.

I have this html markup:

<p id="test" contenteditable >Hello World</p>

I've tried these without any success(JSBin):

var test = document.querySelector('#test');
test.addEventListener('change', function(){
  alert('content edited');
}, false);
test.addEventListener('DOMCharacterDataModified', function(){
  alert('content edited');
}, false);
test.addEventListener('focus', function(){
  alert('content edited');
}, false);

I don't want to listen to keyboard or mouse events. I didn't find any clear documentation in W3C and MDN about contenteditable.

Is it possible to listen to change and focus or other events on a content editable HTML element?

Answer 1

Not really. There is no change event for contenteditable elements, and there's no HTML5 input event either, although I think that will eventually appear. It's a pain.

UPDATE 23 June 2012

Recent WebKit supports the HTML5 input event on contenteditable elements, as does Firefox 14.

focus, however, does work, as does DOMCharacterDataModified in most browsers (though notably not IE < 9). See http://jsfiddle.net/UuYQH/112/

By the way, contenteditable is not a Boolean attribute: it requires a value, which should be one of "true", "false", "inherit" and the empty string (which is equivalent to "true").
