Exemple de code pour implémenter toutes les fonctions de sélection et de suppression par lots basées sur vue.js

<template> 
<p class="hello"> 
<ul> <li v-for="(item, index) in proData"> 
<label for=""> 
<input type="checkbox" :value="index" v-model="selectArr"> 
</label>{{item.name}} 
</li>： 
</ul> 
<button type="" @click="del">删除</button>{{selectArr}} 
<label> 
1
<input type="checkbox" class="checkbox" @click="selectAll" />全选 
</label> 
</p> 
</template>
