Vue 方法与事件处理器

<!-- 只有在 keyCode 是 13 时调用 vm.submit() -->
<input v-on:keyup.13="submit">

<!-- 同上 -->
<input v-on:keyup.enter="submit">
<!-- 缩写语法 -->
<input @keyup.enter="submit">

HTML如下：

<template>
<div class="home-body">
  <div class="project-all">
    <template v-for=‘project in projectData‘>
      <div class="name" v-on:click=‘successT($index)‘ v-bind:class="{‘success‘:project.success}">{{project.projectName}}</div>
    </template>
    <div class="name" v-if=‘addp‘ v-on:click=‘addproject‘>新增项目</div>
    <div class="name" v-if=‘!addp‘ v-on:click=‘addproject‘>
      <input type="text" class=‘name-input‘ placeholder=‘请填写项目名称‘ v-on:keyup.enter=‘saveProjectFun‘ v-el:addProject>
    </div>
    <div class="name">
      <input type="text" class=‘name-input‘ placeholder=‘esc‘ v-on:keyup.esc=‘escFun‘>
    </div>
    <div class="name">
      <input type="text" class=‘name-input‘ placeholder=‘delete‘ v-on:keyup.delete=‘deleteFun‘>
    </div>
    <div class="name">
      <input type="text" class=‘name-input‘ placeholder=‘space‘ v-on:keyup.space=‘spaceFun‘>
    </div>
    <div class="name">
      <input type="text" class=‘name-input‘ placeholder=‘up‘ v-on:keyup.up=‘upFun‘>
    </div>
    <div class="name">
      <input type="text" class=‘name-input‘ placeholder=‘down‘ v-on:keyup.down=‘downFun‘>
    </div>
    <div class="name">
      <input type="text" class=‘name-input‘ placeholder=‘left‘ v-on:keyup.left=‘leftFun‘>
    </div>
    <div class="name"> 
      <input type="text" class=‘name-input‘ placeholder=‘right‘ v-on:keyup.right=‘rightFun‘>
    </div>
  </div>
</div>
</template>
