onpropertychange (HTML attribute)




Potentially quite a useful attribute to use for debugging purposes, the onpropertychange attribute can be used to identify when any property of an element is changed, either by the user or as a result of a programmatic change.


No fixed value - could be a call to one or more defined functions or a simple alert() statement.


Non-standard event defined by Microsoft for use in Internet Explorer. May work in some other browsers but cannot be reliably used. Compatibility for this non-standard attribute not tested.
