Example code for implementing checkbox selection and batch deletion functions based on vue.js

This article mainly introduces the use of vue.js to realize the full selection and multiple deletion functions of checkbox. Friends who need it can refer to the

template code:

<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>

script part:

<script>
var proData = [{
  "name": "j1ax"
}, {
  "name": "j2ax"
}, {
  "name": "j3ax"
}, {
  "name": "j4ax"
}]
export default {
  name: &#39;hello&#39;,
  data() {
    return {
      proData: proData,
      selectArr: []
    }
  },
  created() {
    this.$http.get(&#39;/api/home&#39;).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>
