整理文档，搜刮出一个vue事件对象、冒泡、阻止默认行为的代码，稍微整理精简一下做下分享。
事件对象
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<script src="../js/Vue.js" charset="utf-8"></script>
<script type="text/javascript">
window.onload = function(){
var vm = new Vue({
el:'#box',
data:{},
methods:{
show:function(ev){
alert(ev.clientX);
alert(ev.clientY);
}
}
});
}
</script>
</head>
<body>
<div id="box">
<input type="button" name="" value="按钮" @click="show($event)">
</div>
</body>
</html>
事件冒泡
<!DOCTYPE html>

<script type="text/javascript">
window.onload = function(){
var vm = new Vue({
el:'#box',
data:{},
methods:{
show:function(){
alert(111);
//原生的写法
//ev.cancelBubble = true;
},
show2:function(){
alert(222);
}
}
});
}
</script>
</head>
<body>
<div id="box">
<div @click="show2()">
<input type="button" name="" value="按钮" @click.stop="show()">

show: function () {
alert(111)
},
show2: function () {
alert(222)
}
}

</script>
</head>
