兼容firefox,ie,谷歌,阻止浏览器冒泡事件,Firefox不支持event解决方法
// 获取事件function getEvent(){ if(window.event) {return window.event;} func=getEvent.caller; while(func!=null){ var arg0=func.arguments[0]; if(arg0){ if((arg0.constructor==Event || arg0.constructor ==MouseEvent || arg0.constructor==KeyboardEvent) ||(typeof(arg0)=="object" && arg0.preventDefault && arg0.stopPropagation)){ return arg0; } } func=func.caller; } return null;} //阻止冒泡function cancelBubble() { var e=getEvent(); if(window.event){ //e.returnValue=false;//阻止自身行为 e.cancelBubble=true;//阻止冒泡 }else if(e.preventDefault){ //e.preventDefault();//阻止自身行为 e.stopPropagation();//阻止冒泡 } }
