需求

1、搜索具体地址，自动填写经纬度，并在地图上标记

2、点击地图上一点，可重新填写经纬度并且标记

代码

在dom新建div渲染地图

<el-form-item label="店铺地址" prop="address">
 <el-input v-model="fristForm.address"></el-input>
 <el-input
 class="long-lat"
 v-model="fristForm.longitude"
 placeholder="经度"
 ></el-input>
 <el-input
 class="long-lat"
 v-model="fristForm.latitude"
 placeholder="纬度"
 ></el-input>
 <el-button size="mini" type="primary" @click="searchKeyword"
 >搜索</el-button
 >
</el-form-item>
<span class="changeAddress">点击地图更换分店定位地址</span>
<!-- 渲染地图的div容器 -->
<div id="container" class="mapbox"></div>

js定义地图变量并设置需求

var searchService,geocoder,map,markersArray = [];
<script>
export default {
 mounted() {
  this.init();
 },
 methods:{
  init() {
   var that = this;
   var center = new qq.maps.LatLng(39.916527, 116.397128);
   var map = new qq.maps.Map(document.getElementById("container"), {
   center: center,
   zoom: 13
   });
   var latlngBounds = new qq.maps.LatLngBounds();
   qq.maps.event.addListener(map, "click", function(event) {
   console.log(event);
   that.fristForm.longitude = event.latLng.getLng(); // 经度
   that.fristForm.latitude = event.latLng.getLat(); // 纬度

   if (markersArray) {
    for (let i in markersArray) {
    markersArray[i].setMap(null);
    }
   }
   var marker = new qq.maps.Marker({
    map: map,
    position: event.latLng
   });
   markersArray.push(marker);
   });

   geocoder = new qq.maps.Geocoder({
   complete: function(result) {
    console.log(result);
    that.fristForm.longitude = result.detail.location.lng;
    that.fristForm.latitude = result.detail.location.lat;
    map.setCenter(result.detail.location);
    var marker = new qq.maps.Marker({
    map: map,
    position: result.detail.location
    });
    markersArray.push(marker);
   }
   });
  },
 },
 // 搜索地址
 searchKeyword() {
  var keyword = this.fristForm.address;
  this.clearOverlays(markersArray);
  //根据输入的城市设置搜索范围
  // searchService.setLocation("北京");
  //根据输入的关键字在搜索范围内检索
  if (keyword) {
  // searchService.search(keyword);
  geocoder.getLocation(keyword);
  } else {
  alert("请输入地址");
  }
 },
}
</script>
