vue the checkbox style custom rewriting; loop through checkbox, get different v-model binding value; and obtaining the current status checked, and Select Unselect functions.

Began to write this function, I had to Tucao original checkbox, ugly gray small box, although a single box eleUI, mintUI, other frameworks have their optimization, but still do not want this. Then we look at how to deal with it.

 <section class="box">
     <label  :for="item3" @click="chooseType($event,index3)"  v-for="(item3,index3) in type"  class="labelName">
        <input type="checkbox" :value="item3" :id="item3" v-model="checkedValue" class="checkboxList">            // for属性一定要与id一致，原因请看上图
        <div class="name">{{item3}}</div>  // label的值            // checkbox的v-model绑定值一定要是数组
        &nbsp;&nbsp;
        {{checkedValue}}   // 查看值
     </label>
     <button @click="chooseQu">全选</button>
     <button @click="chooseNo">全不选</button>

  </section>

 data: 

data(){
        return{
          checkedValue: [],
          type:['a','b','c','d']   // 测试数据，可在mounted钩子函数中将后台数据赋值
        }
},

methods:

methods:{
        chooseType(e,val){
          console.log(e.target.checked)   // 可获取当前的checked 状态
          console.log(val)                // 可获取到当前的下标。

        },
        chooseQu(){
          // document.querySelectorAll('.checkboxList').setAttribute("checked","true");
          this.checkedValue = this.type ;  //将原数据全部赋值给checkedValue,全部置为true.  
        },
        chooseNo(){
          this.checkedValue = [] ;    // checkedValue 为空即将checkedValue全部置为false,
        }

  }

样式的调整：

// 样式可根据自己的需要，通过控制外层div自行配置，
.box{
  /*display: flex;*/
  /*justify-content: start;*/
  /*align-items: center;*/
}

.labelName{
  width: 25%;
  display: flex;
  justify-content: center;
  margin-bottom: 20px;
}

/*------新-----*/
  input[type=checkbox] {
    width: 20px;                  // 可根据自己的需要进行配置input的大小。
