<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>：

}, {
  "name": "j"2ax"
}, {
  "name": "j"3ax"
}, {
  "name": "j"4ax"
}]
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 { //Implement full selection
        _this.selectArr = [];
        _this.proData.forEach(function(item, i) {
          _this.selectArr.push(i);
        });
      }
    }
  }
}
