Hello, We're working on a project that requires detection of registered event listeners. Our targets are old-style "onclick" attribute bindings, events registered via "addEventListener" (and the IE equivalent), and other custom event libraries such as jQuery's. As far as we can tell, there is no way to determine if an element has an eventListener attached to it, created via "addEventListener". There is a sure way to remove an event (via "removeEventListener"), but we want to enter some code path if and only if an element has an event registered, without altering its eventListener. This is currently not possible. Many discussions about this topic has been raised in the past. This Stackoverflow answer has a good summary: http://stackoverflow.com/questions/7810534/have-any-browsers-implemented-the-dom3-eventlistenerlist As far as the author could tell, this feature was never implemented due to a lack of a use-case. We have a use-case. Could someone share some thoughts on this? We are also happy to hear workarounds, if anyone has previously encountered this issue and found a way. Cheers, Xav
