v-on可以监听多个方法
<template>
<div class="about">
<button @click="myclick('hello','world','你好世界',$event)">点我text</button> <!-- v-on在vue2.x中测试,以下两种均可-->
<button v-on="{mouseenter: onEnter,mouseleave: onLeave}">鼠标进来1</button>
<button @mouseenter="onEnter" @mouseleave="onLeave">鼠标进来2</button> <!-- 一个事件绑定多个函数，按顺序执行，这里分隔函数可以用逗号也可以用分号-->
<button @click="a(),b()">点我ab</button>
<button @click="one()">点我onetwothree</button> <!-- v-on修饰符 .stop .prevent .capture .self 以及指定按键.{keyCode|keyAlias} -->
<!-- 这里的.stop 和 .prevent也可以通过传入&event进行操作 -->
<!-- 全部按键别名有：enter tab delete esc space up down left right -->
<form @keyup.delete="onKeyup" @submit.prevent="onSubmit">
<input type="text" placeholder="在这里按delete">
<button type="submit">点我提交</button>
</form>
</div>
