addEventListener in Internet Explorer

Question

What is the equivalent to the Element Object in Internet Explorer 9?

if (!Element.prototype.addEventListener) {     Element.prototype.addEventListener = function() { .. }  }  

How does it works in Internet Explorer?

If there's a function equal to addEventListener and I don't know, explain please.

Any help would be appreciated. Feel free to suggest a completely different way of solving the problem.

addEventListener is the proper DOM method to use for attaching event handlers.

Internet Explorer (up to version 8) used an alternate attachEvent method.

Internet Explorer 9 supports the proper addEventListener method.

The following should be an attempt to write a cross-browser addEvent function.

function addEvent(evnt, elem, func) {    if (elem.addEventListener)  // W3C DOM       elem.addEventListener(evnt,func,false);    else if (elem.attachEvent) { // IE DOM       elem.attachEvent("on"+evnt, func);    }    else { // No much to do       elem["on"+evnt] = func;    } }
