Internet-Explorer – Firebreath: Multiple event listeners of a firebreath event in window plug-in

I created a demo JS code to check mousedown event handling.

For ordinary dom elements, mousedown should warn 1 and 2. Why is it not In the same situation as the windowed plugin, I have subscribed 2 event handlers for a Plugin mousedown event?

It only triggers the alert box that displays the message “1”. How to display the second alert box on IE9, 11, 8, Chrome and Firefox, and display the message “2 on this single mousedown event” ”.






Well, first of all, the event should be all lowercase. The event should not be “opened” in it. I don’t see your C code here, it’s hard to tell you What may be the problem.
