Internet Explorer中的addEventListener

addEventListener

Internet Explorer（版本8之前）使用了另

attachEvent

Internet Explorer 9支持正确的

addEventListener

以下应尝试编写跨浏览器

addEvent

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;   }}
