JS的事件对象(Event)
2010-12-06 07:22:21 来源:WEB开发网核心提示:<html><head><title></title></head><body> <div id="contentq" onclick="bb(event)"><!--显示传入even
<html> <head> <title></title> </head> <body> <div id="contentq" onclick="bb(event)"><!--显示传入event对象--> fasdf </div> </body> <script type="text/javascript"> function bb(e){ alert(e); } var container = document.getElementById("contentq"); container.onclick=function(e){ if(document.all){//IE var a=window.event; alert(a.type); }else{ alert(e.type); } } </script> </html>
事件对象获取统一的方法
function getEvent(event) { var ev = event || window.event; if (!ev) { var c = this.getEvent.caller; while (c) { ev = c.arguments[0]; if (ev && (Event == ev.constructor || MouseEvent == ev.constructor)) { /怿飞注:YUI 源码 BUG,ev.constructor 也可能是 MouseEvent,不一定是 Event break; } c = c.caller; } } return ev; }
调用执行的是:
function foo(){ var e = getEvent(); alert(e); }
