js event事件的传递与冒泡处理_javascript技巧

onclick="gotClick(event,'按钮',this);" id="button">

js文件

function gotClick(event,msg,obj){
var object;
var msgs = msg+" => 被单击了!
";
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);
// event.cancelBubble=true;//阻止传递
document.getElementById('result').innerHTML +=msgs;
}
}catch(e){
alert(e);
}

}

运行结果是:

按钮 => 被单击了!
td => 被单击了!
tr => 被单击了!
table => 被单击了!
