**以下是实现方案**

使用数据控制checkbox的勾选状态，感觉这种方式不同于jquery的直接操作DOM，刚刚开始使用真的搞不懂，思路一时转不过来，遇到同样问题的同学可以参考我这个做法，有疑问的同学可以留言。

<template>
    <div class="content">
    <div class="power">
    <h4>权限设置</h4>
    <div v-for="(permissionTop, topIndex) in tableData" :key="topIndex" >
    <p class="checkGroup" style="width:99%;">
    <el-checkbox :indeterminate="permissionTop.indeterminate" :key="topIndex" v-model="permissionTop.mychecked" :label="permissionTop.permissionId" @change="onChangeTop(topIndex, permissionTop.permissionId, $event)">{
       {permissionTop.permissionName}}</el-checkbox>
    </p>
    <div style="margin: 15px 0;"></div>
    <el-checkbox v-for="permissionSon in permissionTop.childrenList" v-model="permissionSon.mychecked" @change="onChangeSon(topIndex, permissionSon.permissionId, permissionTop.permissionId, $event)" :label="permissionSon.permissionId" :key="permissionSon.permissionId">{
       {permissionSon.permissionName}}</el-checkbox>
    </div>
    <el-button class="keep" @click="submitOperatorInfo" >保存</el-button>
    </div>
    </div>
    </template>

事件方法：

data(){
            return{
                tableData: [
                {
                    "childrenList": [
                        {"createTime": 1533707273000,"mychecked": false,"indeterminate": false,"parentPermId": 15,"permissionId": 21,"permissionKey": "orderForm","permissionName": "订单","permissionPath": "","showFlag": "1"},

                params.append('permissionList[]', permissionArray);//权限ID
                Api.admin.post('/login/addOperators', params).then(resp => {
                    if (resp.data.code == 1) {//成功
                        window.location.href = "/ShopManage";//刷新账户管理
                    } else return this.$message(resp.data.msg);
                });
            }
        }

mycheck是控制checkbox的勾选状态，indeterminate则是控制checkbox不确定状态。
