夺命雷公狗jquery---26事件冒泡介绍和阻止方法

什么是事件冒泡可以通过以下代码即可知晓

 

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <title></title>
        <style type="text/css">
            #div1{
                width:400px;
                height:400px;
                background-color:red;
            }

            #div2{
                width:300px;
                height:300px;
                background-color:blue;
            }

            #div3{
                    width:200px;
                    height:200px;
                    background-color:green;
            }
        </style>
        <script src="js/jquery.js"></script>
        <script>
            $(function(){
                $('#div1').bind('click',function(){
                    alert('div1');
                });
                
                $('#div2').bind('click',function(){
                    alert('div2');
                });

                $('#div3').bind('click',function(){
                    alert('div3');
                });
            })
        </script>
    </head>
    <body>
        <div id="div1">
            <div id="div2">
                <div id="div3"></div>
            </div>
        </div>
    </body>
</html>

 

 

阻止的方法其实也很简单，只要加上event  和event.stopPropagetion（）即可阻止事件冒泡了，如下代码所示

 

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <title></title>
        <style type="text/css">
            #div1{
                width:400px;
                height:400px;
                background-color:red;
            }

            #div2{
                width:300px;
                height:300px;
                background-color:blue;
            }

            #div3{
                    width:200px;
                    height:200px;
                    background-color:green;
            }
        </style>
        <script src="js/jquery.js"></script>
        <script>
            $(function(){
                $('#div1').bind('click',function(){
                    alert('div1');
                });
                
                $('#div2').bind('click',function(event){
                    alert('div2');
                    event.stopPropagation();
                });

                $('#div3').bind('click',function(event){
                    alert('div3');
                    event.stopPropagation();
                });
            })
        </script>
    </head>
    <body>
        <div id="div1">
            <div id="div2">
                <div id="div3"></div>
            </div>
        </div>
    </body>
</html>
