复制代码 代码如下:
function gotClick(event,msg,obj){
var object;
var msgs = msg+" => 被单击了!<br/>";
try{
if (event.target) {//Mozilla
object = event.target;
// alert(document.getElementById(object.id).nodeName+" Mozilla "+msg);
document.getElementById('result').innerHTML +=msgs;
// event.cancelBubble=true;//阻止传递
}
else if(event.srcElement){//IE
object = event.srcElement;
// alert(object.id+" IE "+msg);
