vue移动端地址三级联动组件(一)

vue移动端地区三级联动 省，市，县。用的vue+mintUi 因为多级联动以及地区的规则比较多。正好有时间自己写了一个。有问题以及建议欢迎指出。涉及到dom移动，所以依赖vue+jquery。这边数据是后端请求的。我只简单写了三个mock数据。（二）中简单写一下展示以及父级组件。

city.vue 子组件:

html：

<template>
    <div id="city" v-if="showModel">
        <div class="bg"></div>
        <div class="city">
            <div>
