如何防止jQuery事件冒泡到父元素？
为了防止jQuery事件冒泡到父元素，请使用stopPropogation()方法。该stopPropagation()方法停止将事件冒泡到父元素，从而防止任何父处理程序收到该事件的通知。
示例
您可以尝试运行以下代码，以防止jQuery事件冒泡至父元素-
<html>
<head>
<title>jQuery stopProagation() method</title>
<script src = "https://cdn.staticfile.org/jquery/2.1.3/jquery.min.js"></script>
<script>
$(document).ready(function() {
$("div").click(function(event){
alert("This is : " + $(this).text());
event.stopPropagation();
});
});
</script>
<style>
div {
margin:20px;
padding:20px;
border:2px solid #666;
width:160px;
}
</style>
</head>
<body>
<p>Click on any box to see the effect:</p>
<div id = "div1" style = "background-color:green;">
OUTER BOX
<div id = "div2" style = "background-color:gray;">
INNER BOX
</div>
</div>
</body>
</html>
