vue结合element-ui实现二级复选框checkbox
vue结合element-ui实现二级复选框checkbox
话不多说先上效果
交互：1、点击按钮全选，所有的checkbox全部选中；点击清空，所有的checkbox框都不选；点击确定获取选中的checkbox对应的ID数组
2、点击右上角的全选，对应的二级都选中，反之都取消选中，当二级都选中时，对应的一级选中
上代码：
<template>
<div class="checkboxgroup">
<el-button type="primary" @click="handleFilterClassify">点击筛选品类</el-button>
<el-row>
<el-col :span="24"><p></p><span>选中的id数组:</span><span>{{checkedClassify}}</span></el-col>
</el-row><el-row>
<el-col :span="24"><p><span>选中的name数组:</span><span>{{checkedClassifyName}}</span></p></el-col>
</el-row>
<!-- 当前品类弹窗 -->
