短信预约 -IT技能 免费直播动态提醒
本文实例为大家分享了Vue自定义省市区三级联动的具体代码，供大家参考，具体内容如下
1.如图（省市区加上全部联动）
第一步:找到了一个普通的省市区先进行遍历更改
2.把更改后的json文件放入vue项目中引入到你想要的页面
3.剩余代码如下
<template>
<div class="percentloop">
<!-- 地区选择 -->

<p class="tittle">
<span class="important_font">*</span>
<span>地区筛选</span>

</div>
<ul v-show="showindex[0]">
<li v-for="(item,index) in areaList" :key="index"
@click.stop="selprovinceName(index,item.provinceName)">
