[JavaScript知识库]vue zhong echarts.bmap

1.创建bmap.js

import "echarts/extension/bmap/bmap.js";
export function MP(ak) {
  return new Promise(function (resolve, reject) {
    window.onload = function () {
      resolve(BMap)
    }
    var script = document.createElement("script");
    script.type = "text/javascript";
    script.src = "http://api.map.baidu.com/api?v=3.0&ak=" + ak + "&callback=init";
    script.onerror = reject;
    document.head.appendChild(script);
  })
}

2.页面中

import { MP } from "@/bmap.js";
  mounted() {
  this.$nextTick(() => {
      let _this = this;
      MP("ouRIeiXUwefUtUxhMC5DDWHFL4WgU8tU").then((BMap) => {
        _this.$refs.busMap.style.height =
          window.screen.availHeight * 0.9 + "px";
        _this.$nextTick(() => {
          _this.draw(BMap);
        });
      });
    });
