Blocked by: Blocking:


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.

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