本文介绍了vue mint-ui 实现省市区街道4级联动示例(仿淘宝京东收货地址4级联动)

先去下载一个“省份、城市、区县、乡镇” 四级联动数据，然后

引入

import { Picker } from 'mint-ui'; //前提是npm install mint-ui -S

Vue.component(Picker.name, Picker);

组件使用

 <mt-picker :slots="addressSlots" class="picker" @change="onAddressChange" :visible-item-count="5" ></mt-picker >

<mt-picker :slots="streetSlots" ref="picker" class="picker" @change="onStreetChange" :visible-item-count="5" ></mt-picker >
上门服务地址:{{ addressProvince }} {{ addressCity }}

组件方法

<script type="text/ecmascript-6" >
 
 import s from '../../statics/mobile/json/address4.json'
 
 export default {
 name: 'address',
 data () {
 return {
 companyName:'',
 addressSlots: [
 {
 flex: 1,
 defaultIndex: 1,
 values: Object.keys(s),
 className: 'slot1',
 textAlign: 'center'
 }, {
 divider: true,
 content: '-',
 className: 'slot2'
 }, {
 flex: 1,
 values: [],
 className: 'slot3',
 textAlign: 'center'
 }, {
 divider: true,
 content: '-',
 className: 'slot4'
 }, {
 flex: 1,
 values: [],
 className: 'slot5',
 textAlign: 'center'
 }
 ],
 streetSlots: [
 {
 flex: 1,
 values: [],
 className: 'slot1',
 textAlign: 'center'
 }
 ],
 addressProvince: '省',
 addressCity: '市',
 addressXian: '区',
 addressStreet: '街道',
 
 }
 },
 methods: {
 
 onAddressChange(picker, values) {
 let sheng = Object.keys(s);
 let shi = Object.keys(s[values[0]]);

　　　　　　let index=shi.indexOf(values[1])
　　　　　　let xian = s[values[0]][shi[index]];
　　　　　this.xianObj = xian;
 picker.setSlotValues(1, shi);
 this.addressProvince = values[0];
 this.addressCity = values[1];
 this.addressXian = values[2];
 picker.setSlotValues(2, Object.keys(xian));
 },
 onStreetChange(picker, values){
 this.addressStreet = values[0]
 },
 
 
 },
 watch: {
 'addressXian': {
 handler(val, oval){
 let street = this.xianObj[this.addressXian]
 this.streetSlots[0].values = street
 }
 }
 },
 created(){
 
 },
 mounted(){
 this.$nextTick(() => {
 setTimeout(() => {//这个是一个初始化默认值的一个技巧
 this.addressSlots[0].defaultIndex = 0;
 }, 100);
 });



 }
 }
</script >
