整理文档，搜刮出一个vue2.0的contextmenu右键弹出菜单的实例代码，稍微整理精简一下做下分享。
1.事情对象
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta charset="utf-8">
<script src="http://unpkg.com/vue/dist/vue.js"></script>
<script type="text/javascript">
window.onload = function(){
var vm = new Vue({
el:'#box',
methods:{
show:function(event){
console.log(event); //event 这个就是事件对象了
}
}
});
}
</script>
</head>
<body>
<div id="box">
<input type="button" value="按钮" @click="show($event)">
</div>
</body>
</html>
通过show($event)把事件对象传到方法里
2.事件冒泡
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta charset="utf-8">
<script src="http://unpkg.com/vue/dist/vue.js"></script>
<script type="text/javascript">
window.onload = function(){
var vm = new Vue({
el:'#box',
methods:{
show:function(){
alert(1);
},
show1:function(){
alert(2);
}
}
});
}
</script>
</head>
<body>
<div id="box">
<div @click="show1()">
<input type="button" value="按钮" @click="show()">
</div>
</div>
</body>
</html>
点击按钮的话他会，执行show ,show1方法，依次弹出1，2。
怎么来阻止
<1> 利用我们上面讲过的event对象: event.cancelBubble = true; //这种就阻止了
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta charset="utf-8">
<script src="http://unpkg.com/vue/dist/vue.js"></script>
<script type="text/javascript">
window.onload = function(){
var vm = new Vue({
el:'#box',
methods:{
show:function(event){
alert(1);
event.cancelBubble = true;
},
show1:function(){
alert(2);
}
}
});
}
</script>
</head>
<body>
<div id="box">
<div @click="show1()">
<input type="button" value="按钮" @click="show($event)">
</div>
</div>
</body>
</html><2>利用vue的方法阻止冒泡：给HTML元素绑定click事件的时候，改为@click.stop="show()"
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta charset="utf-8">
<script src="http://unpkg.com/vue/dist/vue.js"></script>
<script type="text/javascript">
window.onload = function(){
var vm = new Vue({
el:'#box',
methods:{
show:function(event){
alert(1);
//event.cancelBubble = true;
},
show1:function(){
alert(2);
}
}
});
}
</script>
</head>
<body>
<div id="box">
<div @click="show1()">
<input type="button" value="按钮" @click.stop="show()">
</div>
</div>
</body>
</html>
3.默认行为
比如contextmenu右键菜单
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta charset="utf-8">
<!-- // <script src="vue.js"></script> -->
<script src="http://unpkg.com/vue/dist/vue.js"></script>
<script type="text/javascript">
window.onload = function(){
var vm = new Vue({
el:'#box',
methods:{
show:function(){
alert(1);
},
show1:function(){
alert(2);
}
}
});
}
</script>
</head>
<body>
<div id="box">
<input type="button" value="按钮" @contextmenu="show()">
<input type="button" value="按钮1" @contextmenu.prevent="show1()">
<p>//按钮右击点下去会依次出现 弹窗 1， 还有右击的默认菜单</p>
<p>//按钮1右击只出现 弹窗 2</p>
</div>
</body>
</html>
