公司 pc 端有一个地图选址及查看地图功能,这个是几个月前就开发完了,最近欠缺了一下,先上最终成果吧。

抉择省市区填写具体地址进入点击确认坐标关上地图弹框

依据传入的地址查问到了地址能够查看更多地址,能够点击地图查看周边,点击确认,获取坐标。


这是查看地址

好了,上实现代码。

<template>
  <el-dialog title="":close-on-click-modal="false":destroy-on-close="true":visible.sync="visibleVal":modal="modal"width="800px"class="x-ui-modal map__dialog">

    <div id="container"></div>

    <div class="poi__list" ref="scrollWrap" v-if="lists.length">
      <div class="ul">
        <div class="address-item"
          :class="nearbyIndex === choiceIndex ?'active':''"
          @click.stop="choiceAddress(nearbyIndex)" 
          v-for="(nearby, nearbyIndex) in lists" :key="nearbyIndex">
          <div class="icon"></div>
          <div class="text">
            <div class="name" :title="nearby.name">{{nearby.name | ellipsis}}</div>
            <div class="address" :title="nearby.address">{{nearby.address | ellipsis}}</div>
          </div>
        </div>
        <div v-show="bottomLoadingShow"><Loading /></div>
        <div v-show="bottomLineShow"><BottomLine :text="'已无更多数据,点击地图 \n 任意一处能够查看周边'"/></div>
        <div v-show="moreShow" @click="loadingMore"><BottomLine :text="'上拉或点我查看更多'" style="cursor: pointer;" /></div>
      </div>
    </div>

    <div 
      v-if="isEdit"
      class="city__name"
      :title="` 您查问的 ${customerName ?' 客户及地址 ':' 地址 '}:${searchKwords}`">
      <el-input
        v-model="searchKwords"
        disabled />
    </div>

    <template v-if="isEdit">
      <div class="main__footer">
        <el-button
          @click="onCloseModal()"
          class="x-ui-btn add__cancel"
          size="medium"> 勾销 </el-button>
        <el-button
          @click="onSubmit()"
          class="x-ui-btn add__submit"
          type="primary"
          size="medium"> 确认 </el-button>
      </div>
    </template>

    <template v-else>
      <div class="main__footer">
        <el-button
          @click="onCloseModal()"
          class="x-ui-btn add__cancel"
          size="medium"> 敞开 </el-button>
      </div>
    </template>
  </el-dialog>
</template>

以上是 dom,用的是 element-ui 的 dialog。

进入弹框后,编辑加载须要用到的地图插件,AMap.Geocoder 和 AMap.PlaceSearch,因为一开始做这个是时候,独自应用了一种 AMap.Geocoder,很多高德地图上能查到的地址都定位不到,于是查看了文档的常见问题,外面的形容就是:“高德地图的搜寻是复合型搜寻 …… 地位搜寻的研发中,能够先进行地址解析,再进行关键词搜寻,以失去更优的后果。”查看则间接依据内部传入的经纬度定位,初始化地图。当然我这里是在保障 AMap 和 AMapUI 都曾经加载到的状况下再做的,否则就会报错,我用了比拟笨的方法,就是定时器一直执行加载的代码,而后在这里一旦两个都有了,就进行定时器,比拟笨的方法了。

上面就是编辑坐标时的逻辑了

interval() {this.timer = setInterval(function() {this.awaitPlaceSearch();
      }.bind(this), 50)
    },

    awaitPlaceSearch() {if(this.placeSearch && this.geoCoder) {clearInterval(this.timer);
        this.isUseNearBy = false;
        this.placeSearch.search(this.handleCityName, (status, result) => {if (status === 'complete') {if(result.poiList.pois.length) {if(result.poiList.pois.length % this.pageSize !== 0) {
                this.isUseNearBy = true;
                this.bottomLineShow = true;
              } else {
                this.isUseNearBy = false;
                this.bottomLineShow = false;
              }
              const geos = result.poiList.pois[0].location;
              this.center = [geos.lng, geos.lat];
              this.getAreaInfo('location', (res) => {
                this.lists = result.poiList.pois// 将查问到的地点赋值
                this._initScroll();
                this.getAddress(0);
                this.createdMap([this.ruleForm.long, this.ruleForm.lat]);
                this.addMarker();})
            } else {if(result.cityList && result.cityList.length > 1) {this.lists = [];
                this.onCloseModal();
                this.$message.info(` 以后搜寻地址在 ${result.cityList.length}个城市有若干后果,请明确后再搜寻 `);
              } else {this.lists = [];
                this.onCloseModal();
                this.$message.info('未能查问到该地址,请更换关键字查问');
              }
            }
          } else if(status === 'no_data') {this.$message.warning(` 您输出的地址“${this.cityName}”,未查问到相干信息 `);
            this.getAreaInfo('address', (res) => {
              this.lists = [
                {
                  location: {lng: res.geocodes[0].location.lng,
                    lat: res.geocodes[0].location.lat,
                  },
                  name: res.geocodes[0].formattedAddress,
                  address: '',
                }
              ]
              this.center = [res.geocodes[0].location.lng, res.geocodes[0].location.lat]
              this._initScroll();
              this.getAddress(0);
              this.createdMap([this.ruleForm.long, this.ruleForm.lat]);
              this.addMarker();
              this.isUseNearBy = true;
              this.bottomLineShow = true;
            });
          } else {this.fixedPosition();// 精准定位或 IP 地址定位
          }
        }) 
      }
    },

当然也是在保障 this.placeSearch 和 this.geoCoder(即 AMap.Geocoder 和 AMap.PlaceSearch)都加载到,同样也是下面说的笨办法。我是先用 AMap.PlaceSearch.search 办法,通过关键字查问传入的地址,如果查问到,则确定新的地图中心点经纬度,再通过 AMap.Geocoder.getAddress 办法传入新的地图中心点经纬度,解析出省市区信息,也可能关键字查问不明确(未明确省市区),比方只写了 xx 路,就有可能在全国多处都有后果,则会敞开弹框,提醒明确后再查问,还可能关键字基本就查问不到,AMap.PlaceSearch.search 返回 no_data,则传入关键字应用 AMap.Geocoder.getLocation 办法,解析关键字所在城市,总之这里的逻辑就是 AMap.Geocoder 和 AMap.PlaceSearch 搭配应用。此处 this.getAreaInfo 办法是解析地址省市区的办法,设置了一个回调函数作为参数:

// 依赖高德该接口取得省市区信息
    getAreaInfo(type, callback) {if(type === 'address') { // 在编辑的状况下通过地址名称查问
        this.geoCoder.getLocation(this.handleCityName, (status, result) => {if (status === 'complete' && result.geocodes.length) {this.ruleForm.regeocode.adcode = result.geocodes[0].adcode
            this.ruleForm.regeocode.province = result.geocodes[0].addressComponent.province
            this.ruleForm.regeocode.city = result.geocodes[0].addressComponent.city == '' ? result.geocodes[0].addressComponent.province : result.geocodes[0].addressComponent.city
            this.ruleForm.regeocode.district = result.geocodes[0].addressComponent.district;
            callback(result);
          } else if(status === 'no_data') {this.lists = [];
            this.onCloseModal();
            this.$message.info('未能查问到该地址,请更换关键字查问');
          } else {this.fixedPosition();// 精准定位或 IP 地址定位
          }
        });
      } else if(type === 'location') { // 在查看的状况下通过经纬度查问
        this.geoCoder.getAddress(this.center, (status, result) => {if (status === 'complete' && result.regeocode && result.regeocode.addressComponent) {
            this.ruleForm.regeocode.adcode = result.regeocode.addressComponent.adcode
            this.ruleForm.regeocode.province = result.regeocode.addressComponent.province
            this.ruleForm.regeocode.city = result.regeocode.addressComponent.city == '' ? result.regeocode.addressComponent.province : result.regeocode.addressComponent.city
            this.ruleForm.regeocode.district = result.regeocode.addressComponent.district;
            callback(result);
          } else {this.fixedPosition();// 精准定位或 IP 地址定位
          }
        });
      }
    },

以上在获取到地址时都会设置为一个地址列表,设置在地图左侧,供用户抉择,滚动应用 better-scroll,能够上拉加载进行分页,这里不开展说了。

通过以上步骤,大部分状况下都能查问到准确的关键字,一部分高德没有收录的企业信息,也能定位到所在街道乡镇省市区。此外还在点击地图的时候触发了 AMap.PlaceSearch.searchNearBy 办法查问鼠标点击处的周边,作为补充:

// 查看更多,此办法也给上拉加载应用
searchMore(e) {if(e) {
        this.isUseNearBy = true;
        this.placeSearch.opt.pageIndex = 1;
        this.center = [e.lnglat.getLng(), e.lnglat.getLat()];
      } else {this.placeSearch.opt.pageIndex += 1;}
      this.geoCoder.getAddress(this.center, (status, result) => {if (status === 'complete' && result.info === 'OK') {
          let addressComponent = result.regeocode.addressComponent;
          this.ruleForm.regeocode.adcode = addressComponent.adcode
          this.ruleForm.regeocode.province = addressComponent.province
          this.ruleForm.regeocode.city = addressComponent.city == '' ? addressComponent.province : addressComponent.city
          this.ruleForm.regeocode.district = addressComponent.district;

          let cityName = this.isUseNearBy ? '' : this.handleCityName;
          if(this.isUseNearBy) {this.placeSearch.searchNearBy(cityName, this.center, 1000, (status, result) => {this.searchCallBack(status, result, e)
            });
          } else {this.placeSearch.search(cityName, (status, result, e) => {this.searchCallBack(status, result)
            });
          }
        } else {this.emptyLocationData();
        }
      })
    },
    searchCallBack(status, result, event) {if (status === 'complete' && result.poiList.pois.length) {if(event) {
          this.lists = result.poiList.pois;
          if(this.lists.length % this.pageSize !== 0) {this.bottomLineShow = true;} else {this.bottomLineShow = false;}
          this.getAddress(0);
          if(this.scroll) {this.scroll.scrollTo(0, 0);
            this.scroll.finishPullUp();} else {this._initScroll();
          }
          this.addMarker();} else {this.lists = concat(this.lists, result.poiList.pois);
          if(this.lists.length % this.pageSize !== 0) {this.bottomLineShow = true;} else {this.bottomLineShow = false;}
          this.originalStatus();}
      } else {this.bottomLineShow = true;}
    },

次要的局部就是下面这些,还有一些外面用到的办法,我截几张图吧,第一次写文章,写的比拟乱。
