组件内容为：

<template>
  <a-modal v-model="visibleMap" title="选择地点" @cancel="handleCancelMap" width="80%">
    <iframe width="100%" style="height: 60vh; width: 76vw; border: none;" :src="map_src"></iframe>
    <template slot="footer">
      <a-button @click="handleSureMap" type='primary'>确定</a-button>
      <a-button @click="handleCancelMap" type='primary'>取消</a-button>
    </template>
  </a-modal>
</template>

<script>
  export default {
    name: 'mapComponents',
    props: {
      visibleMap: {
        type: Boolean,

          id_area: [
            0,
            0,
            0
          ],
          address: '',

      }

    created() {

      window.addEventListener('message', function(event) {
        // 接收位置信息，用户选择确认位置点后选点组件会触发该事件，回传用户的位置信息
        var loc = event.data;
        console.log(loc)
        if (loc && loc.module == 'locationPicker') { //防止其他应用也会向该页面post信息，需判断module是否为'locationPicker'
          that.map_data.address = loc.poiaddress
          that.map_data.lat = loc.latlng.lat
          that.map_data.lng = loc.latlng.lng
          that.$emit('chooseMapPoint',that.map_data)
        } else {
          that.$emit('chooseMapPoint','选择数据为空')
        }
      }, false);
    },
    methods: {
      //地图选点确定
      handleSureMap() {
        this.$emit('sure', this.map_data)
      },
      // 取消
      handleCancelMap () {
        this.$emit('cancel')
      },
    }
  }
</script>

<style>
</style>

使用：

<MapComponent :visibleMap='visibleMap' @chooseMapPoint='getCallMap' @cancel='cancelMap' @sure='sureMap'></MapComponent>
methods:{
	getCallMap (e) {
        console.log(e)
      },
      cancelMap () {
        this.visibleMap = false
      },
      sureMap(e){
        console.log(e)
      },
}

（腾讯地图文档上的那个链接太离谱了，用这个https://mapapi.qq.com/web/mapComponents/locationPicker/v/index.html?search=1&type=1&key=这里放你使用的key&referer=location就行）
