解决事件冒泡兼容性问题
① 在public.js函数库中创建stopBubble函数
② 判断浏览器类型
//冒泡兼容性问题
function stopBubble(event){
if(window.event){
//IE
window.event.cancelBubble = true;
}else{
event.stopPropagation();
}
}
③ 在html页面测试stopBubble函数
<!DOCTYPE html>
<html>
<head>
<meta charset=’utf-8′>
<title></title>
<style type=”text/css”>
div#div1{
width:500px;
height:500px;
background:red;
}
div#div2{
width:400px;
height:400px;
background:blue;
}
div#div3{
width:300px;
height:300px;
background:yellow;
}
</style>
<script src=”public.js”></script>
<script>
window.onload = function(){
addEvent($(‘div1′),’click’,function(){
alert(‘div1′);
})
addEvent($(‘div2′),’click’,function(){
alert(‘div2′);
//IE模型
//window.event.cancelBubble = true;
//w3c
//event.stopPropagation();
stopBubble(event);
})
addEvent($(‘div3′),’click’,function(){
alert(‘div3′);
//IE模型
//window.event.cancelBubble = true;
//w3c
//event.stopPropagation();
stopBubble(event);
})
}
</script>
</head>
<body>
<div id=”div1″>
<div id=”div2″>
<div id=’div3′></div>
</div>
</div>
</body>
</html>
