vue 使用echarts地图实现全国地图_echarts.getmap

代码参考来自 <https://www.cnblogs.com/lude1994/p/12482355.html>

json数据自己收集保存，包含世界坐标、全国坐标及各省份内的坐标

1.安装echarts

npm install echarts --save

 

2.在main.js中引入

import echarts from 'echarts';
 
//引入遇到报错 "export ‘default’ (imported as ‘echarts’) was not found in ‘echarts’
 
//新版本需要使用该代码引入 ：const echarts = require('echarts');
 
 
 
import 'echarts/map/js/china.js'; //node_modules中 官方依赖已不提供map文件 需要自行导入其中
 
Vue.prototype.$echarts = echarts

3.在页面中使用：

<div ref="map" style="height:300px;" ></div>

4.将函数写在methods中，然后再mounted中调用

js函数方法：

getmap() {
      // 基于准备好的dom(myEchartPillar)，初始化echarts实例
      let myChart = this.$echarts.init(this.$refs.map);
      this.$echarts.registerMap('china',china);
 
      var mapName = 'china'
      var data = [
        {
          code: "10",
          name: "其他",
