用vue脚手架写的简易留言板

1.配置安装好脚手架
2.留言板：

<template>
<div class="about">
<input type="text" v-model="value" @keydown.enter="add" />
<button @click="add">提交</button>
<h1>{{value}}</h1>
<h3>未完成({{listno.length}})：</h3>
<button @click="dels1(index)">全部删除</button>
<table>
<tr>
<th>选项</th>
<th>内容</th>
<th>提交时间</th>
<th>间隔时间</th>
<th>操作</th>
</tr>
<tr v-for="(item, index) in listno" :key="index">
<td>
<input type="checkbox" @click.prevent="changeYes($event,item,index)" />
</td>
<td>
<span v-if="item.isShow">{{item.text}}</span>
<input type="text" v-model="item.text" @blur="updateblur1(index)" v-else autofocus />

<td>
<button @click="del1(index)">删除</button>
<button @click="update1(index)">修改</button>
