Vue+Tencent location service realizes coordinate picker function

demand

1. Search for a specific address, automatically fill in the latitude and longitude, and mark it on the map

2. Click on a point on the map to refill the latitude and longitude and mark

Code

• Create a new div in dom to render the map

<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 defines map variables and sets requirements

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>
