vue中实现百度地图全国与省市地图切换

前言

本文主要是用于示例全国地图，点击省市地图直接跳转到该省市地图并展示，可以拓展在地图上显示标记点（本文未做示例），后续有完整代码，但是由于需要与本来项目业务代码进项分割，可能会有些问题，地图渲染上所需要的json文件，有资源链接，但是需要积分，在网上搜搜也会有相关资源，不是非必要使用该json文件，注意一下导入的文件名称即可

二、完整代码

一、示例代码

1.1 地图json文件

资源地址：百度地图全国以及各省json文件

1.2 示例解析

1.dom层
默认渲染全国地图，返回按钮主要用于点击省市地图跳转进入省市的地图的时候，设置一个返回按钮，返回到全国地图

 <el-button size="mini"type="primary"v-if="mapBackBtnShow"@click="drawBaiduMap">返回</el-button><div ref="mapChartsRef"style="width: 100%;height: 100%;z-index: 99;"></div>

2.逻辑准备
引入echarts

import * as echarts from 'echarts'

控制返回按钮显示隐藏

mapBackBtnShow: false,

3.主要逻辑方法
