使用vue.js实现checkbox的全选和多个的删除功能

<template> <div 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> <input type="checkbox" class="checkbox" @click="selectAll" />全选 </label> </div> </template>

<script>var proData = [{  "name": "j1ax"}, {  "name": "j2ax"}, {  "name": "j3ax"}, {  "name": "j4ax"}]export default {  name: 'hello',  data() {    return {      proData: proData,      selectArr: []    }  },  created() {    this.$http.get('/api/home').then(function(response) {      response = response.body;      this.proData = response.data;    })  },  methods: {    del() {      let arr = [];      var len = this.proData.length;      for (var i = 0; i < len; i++) {        if (this.selectArr.indexOf(i)>=0) {          console.log(this.selectArr.indexOf(i))        }else{          arr.push(proData[i])        }      }      this.proData = arr;      this.selectArr = []    },    selectAll(event) {      var _this = this;      console.log(event.currentTarget)      if (!event.currentTarget.checked) {        this.selectArr = [];      } else { //实现全选        _this.selectArr = [];        _this.proData.forEach(function(item, i) {          _this.selectArr.push(i);        });      }    }  }}</script>
