A JavaScript function that tests if the browser has support for CSS3 "transitionEnd" event : - If so, it returns a new boolean object which is true and has a property called "event" which contains the supported event name as a string. - If not, it simply returns false. Because it is a CSS3 event, only quite recent browsers won't fail this test.
