When to use event.initMouseEvent for simulating mouse clicks?
- by Protector one
I wonder if there are benign use-cases for simulating mouse clicks using event.initMouseEvent. I found that it is used for creating pop-under ads in the following way:
var e = document.createEvent('MouseEvents');
e.initMouseEvent('click', true, true, window, 0, 0, 0, 0, 0, true, false, false, true, 0, null);
a.dispatchEvent(e);
This code simulates a click on the opening browser window, to force the newly opened window beneath it. Evil.
I'm thinking of simply preventing all simulated clicks in my own browser via a browser extension, but I wonder if I might break useful websites and behavior in the process. Therefore I wonder what situations justify simulating mouse clicks, and if there are big sites that use it in non-evil ways.
