I searched for this but did not find a satisfactory answer. What versions of Internet Explorer, if any, implement the W3C DOM Level 2 event model?
IE 9 must be the first version of IE to add a W3C event model in addition to their own model according to Wikipedia .
Further reading:
I think the browser isnβt working right now.
An excellent resource on which the event is implemented in the browser quirksmode.org compatibility table.
Also read an introduction to events on the same site.
Microsoft did not follow the W3C model until Internet Explorer 8, as their own model was created before the ratification of the W3C standard. Internet Explorer 9 is supposed to keep track of level 3 events.
