安裝Echarts 中國地圖

高德地圖

官方API：點我進入

創建AMap.js

export default function MapLoader () {
    return new Promise((resolve, reject) => {
      if (window.AMap) {
        resolve(window.AMap)
      } else {
      // 動態創建script標簽
        var script = document.createElement("script")
        script.type = "text/javascript"
        script.async = true
        script.src = "https://webapi.amap.com/maps");;
        // plugin后的是需要的插件
        script.onerror = reject
        document.head.appendChild(script)
      }
      window.initAMap = () => {
        resolve(window.AMap)
      }
    })
}

Echarts 中國地圖

安裝Echarts

npm install echarts -S

開始使用

創建組件 distribution.vue

寫入Echarts 需要的DOM

寫入高德地圖需要的DOM

引入高德地圖、Echarts

    import "echarts/map/js/china"; //中國地圖js
    import MapLoader from "components/home/AMap"
