js事件的冒泡和捕获在编程中有什么用?
如题..
[解决办法]
LZ 写的代码少，等代码写多了自然就会用到了！
写个小例子，L@_@K！
<body>
<div id= "divParent " style= "background-color: #ffff00; width: 200px; height: 200px; "> Parent!
<div id= "divChild " style= "background-color: #00ffff; width: 100px; height: 100px; ">
Child!
</div>
</div>
<script type= "text/javascript ">
<!--
var oParent = document.getElementById( "divParent ");
var oChild = document.getElementById( "divChild ");
oParent.onclick = function()
{
alert( "Parent ");
};
oChild.onclick = function()
{
alert( "Child ");
// 停止冒泡！
// 注释看看效果有何不同！
event.cancelBubble = true;
};
//-->
</script>
</body>
