uni-app根据腾讯地图接口三级联动组件

有时候很懵逼，因为需要用到腾讯地图接口的三级联动，习惯问问度娘，结果出来了我几年前用JQ写的，好吧，还是自己撸一个现在用的吧

组件使用得是uni-popup弹窗，picker-view 滑动选择地址

访问腾讯地图接口使用的是 vue-jsonp 

npm install vue-jsonp

在main.js引入

import {
    VueJsonp
} from 'vue-jsonp'
Vue.use(VueJsonp)

组件address.vue

组件只需要填写你自己得腾讯地图的 key就可以了

<template>
	<view class="page-body">

<style lang="scss" scoped>
	.popupBox {
		width: 100%;
		background: #fff;
		.btnBox {
			background: #eee;
			.cancel {
				padding: 20rpx;
			}
			.submit {
				padding: 20rpx;
				color: $red;
			}
		}
		.picker-view {
			height: 50vh;
			text-align: center;
			.item {
				line-height: 50px
			}
		}
	}
</style>

使用方法，直接引入组件使用

<Address @submitAddress="submitAddress" ref="addressPopup"></Address>


methods: {
    selectAddress() {
		this.$refs.addressPopup.open()
	},
	submitAddress(data) {
		this.addressData= data;
	},
}
