<script lang="ts">
import { defineComponent, ref, nextTick, unref, onMounted } from 'vue';
import { useScript } from '/@/hooks/web/useScript';
const BAI_DU_MAP_URL = 'https://api.map.baidu.com/getscript?v=3.0&ak=xxx';

      const BMap = (window as any).BMap;
      const map = new BMap.Map(wrapEl);
      const point = new BMap.Point(116.404, 39.915);
      map.centerAndZoom(point, 15);

vue-class-component写法

<script lang="ts">
import { ref, nextTick, unref } from 'vue'
import {Vue} from 'vue-property-decorator'
import { useScript } from '/@/hooks/web/useScript'
const BAI_DU_MAP_URL = 'https://api.map.baidu.com/getscript?v=3.0&ak=xxx';
export default class LogisticsDetail extends Vue {
  private wrapRef = ref<HTMLDivElement | null>(null)
  private toPromise = useScript({ src: BAI_DU_MAP_URL })
  async initMap() {
    await this.toPromise();
    await nextTick();
    const wrapEl = unref(this.wrapRef);
    if (!wrapEl) return;
    const BMap = (window as any).BMap;
    const map = new BMap.Map(wrapEl);
    const point = new BMap.Point(116.404, 39.915);
    map.centerAndZoom(point, 15);
    map.enableScrollWheelZoom(true);
  }
  mounted() {
    this.initMap()
  }
}</script>
