v-on可以監聽多個方法
<template>
<div class="about">
<button @click="myclick('hello','world','你好世界',$event)">點我text</button>
<!-- v-on在vue2.x中測試,以下兩種均可-->
<button v-on="{mouseenter: onEnter,mouseleave: onLeave}">鼠標進來1</button>
<button @mouseenter="onEnter" @mouseleave="onLeave">鼠標進來2</button>
<!-- 一個事件綁定多個函數，按順序執行，這里分隔函數可以用逗號也可以用分號-->
<button @click="a(),b()">點我ab</button>
<button @click="one()">點我onetwothree</button>
<!-- v-on修飾符 .stop .prevent .capture .self 以及指定按鍵.{keyCode|keyAlias} -->
<!-- 這里的.stop 和 .prevent也可以通過傳入&event進行操作 -->
<!-- 全部按鍵別名有：enter tab delete esc space up down left right -->
<form @keyup.delete="onKeyup" @submit.prevent="onSubmit">
<input type="text" placeholder="在這里按delete">
<button type="submit">點我提交</button>
</form>
</div>
</template>
