Vue实现手机端省市区区域选择_白泊_前端开发者

本文实例为大家分享了vue实现手机端省市区区域选择的具体代码,供大家参考,具体内容如下

1 后端接口获取城市信息

2 先获取省 根据用户点击的省获取市

3 再根据用户点击的市获取区 

组件代码:

<template>
 <div class="city">
 <!-- 点击此处 省市区选择出现 -->
 <div class="chooseCity" @click="clickCity">{{chooseCity}}</div>
 <div class="boxcity" v-if="showCity">
 <!-- 省市区的标题 点击可回退 -->
 <div class="chooseTit">
  <p @click="chooseProvince" v-show='tit1'>{{chooseTit1}}</p>
  <p @click="chooseCity2" v-show='tit2'>{{chooseTit2}}</p>
  <p v-show='tit3'>{{chooseTit3}}</p>
 </div>
 <!-- 省市区 -->
 <div class="citys">
 <div @click="getCity" class="province">
  <ul v-show="showProvince">
  <li v-for="item in provinceL" :key="item.regionId" @click="getProvince(item)">{{item.regionName}}</li>
 </ul>
 <ul v-show="showCity2">
  <li v-for="item in cityL" :key="item.regionId" @click="getCity2(item)">{{item.regionName}}</li>
 </ul>
  <ul v-show="showarea">
  <li v-for="item in areaL" :key="item.regionId" @click="getarea(item)">{{item.regionName}}</li>
 </ul>
 </div>
 </div>
 </div>
 <!-- 遮罩层 -->
 <div class="mask" v-show="mackShow" @click="closeMask"></div>
 </div>
</template>
