Description

Please make isEventSupported public.

jQuery.eventSupported = function( eventName, el ) {
	el = document.createElement(el || "div");
	eventName = "on" + eventName;
	var isSupported = (eventName in el);
	if ( !isSupported ) {
		el.setAttribute(eventName, "return;");
		isSupported = typeof el[eventName] === "function";
	}
	el = null;

	return isSupported;
};

Note the slightly change with el variable.

Could you please provide a use case for this enhancement?

  • Status changed from pending to new

This can be usefull for plugin authors, who are implementing new features based on events, wich are supported in some browsers and in some not. Due to the fact, that this method doesn't work in all browsers with all events, it isn't very important.

  • Status changed from open to closed
  • Resolution set to cantfix
  • Milestone set to 1.6

(Un)fortunately we've removed most of the isEventSupported logic in jQuery 1.6, so this isn't relevant any longer.

Please follow the  bug reporting guidlines and use  jsFiddle when providing test cases and demonstrations instead of pasting the code in the ticket.
