## 一、Echarts官方地图资源 ##

Echarts官方文档已经暂停了地图数据的下载，但是百度Echarts给我们留了下载的**官方接口：`https://echarts.apache.org/examples/vendors/echarts/map/`**

1.  **JSON格式**  
    `https://echarts.apache.org/examples/vendors/echarts/map/json/`  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NTg0NDA0OQ_size_16_color_FFFFFF_t_70_pic_center 1]
2.  **JS格式**  
    `https://echarts.apache.org/examples/vendors/echarts/map/js/`

## 二、实现 ##

1.  **下载china.js文件**  
    `https://echarts.apache.org/examples/vendors/echarts/map/js/china.js`
2.  **放到对应的文件**（我放在了utils里）
3.  **上代码**

<template>
      <div class="managingPatientSize">
        <el-row>
          <el-col :span="6">1</el-col>
          <el-col :span="12">
            <div id="china-map"></div>
          </el-col>
          <el-col :span="6">1</el-col>
        </el-row>
      </div>
    </template>
    
    <script>

          var chinaMap = echarts.init(document.getElementById("china-map"));
          window.onresize = chinaMap.resize; // 窗口或框架被调整大小时执行chinaMap.resize
          chinaMap.setOption({
