Vue2仿淘宝实现省市区三级联动

时间:2024-3-2 04:04     作者:韩俊     分类: Html+Css


三级联动,随着越来越多的审美,出现了很多种,好多公司都仿着淘宝的三级联动 ,好看时尚,so我们公司也一样……为了贴代码方便,我把写在data里面省市区的json独立了出来,下载贴进去即可用,链接如下:vue.json(这个直接是个data,放入你的vue2项目中即可。(因为我的项目是用的vue2,所以,其他的属性跟博客内容是吻合的。请配合博客再下载此json))。

首先页面显示如下:

然后我们县级所在地区会出现三级联动,如下:(以下是片段,背景色未截取)

这个张什么样,以什么形式出现,取决于贵公司的UI需求,我们公司是做成弹出层了。。然后背景色透明,这里为了节省流量,我只截取了一段,最后显示如下:

如果贵公司也跟我们需求一样,希望这个可以帮到你们。下面是在vue2项目中写的三级联动代码以及css样式:
<template>

  <section class="myAddress">
    <section>
      <section class="cont" @click="choseAdd()">
       <section>
         <span>所在地区:{{Province?Province:''}} {{City?City:''}} {{District?District:''}}</span>
       </section>
       <img src="../../assets/main/right.png" alt="">

      </section>
    </section>
    <!-- 居住地址三级联动选项 -->

  .address ul .active {

  }
</style>

这样就完成了一个省市区的三级联动。
