onChange event with contenteditable [duplicate]

Question

Code like:

...text <span contenteditable="true" onChange="someFunction()">blah blah</span> text... 

The onChange event doesn't work. (at least in FireFox)
I don't want to use textarea/input tags, because there must be available to change only particular words in text, and must be displayed inline (not block).

Is there any way how to do that ?

Answer 1

Not really. Recent WebKit browsers support the HTML5 input event on contenteditable elements, which is ideal, but not supported in other browsers (UPDATE 31 December 2012: Firefox supports this as of version 14). Otherwise you may be able to get by with DOM mutation events DOMNodeInserted, DOMNodeRemoved and DOMCharacterDataModified, but these have two disadvantages: firstly, they are not supported in IE < 9 or any version of Opera for contenteditable elements, and secondly, a new spec with replacement events is in the works, meaning they are likely to be replaced in future browsers.

Or you could go lower level and handle key, mouse and clipboard events (cut and paste), which will work in all major browsers but will mean you'll need to check whether the editable content has changed each time such an event fires, which will get laggy and harm user experience for large pieces of content.
