高德地图结合angular4 实现下拉框获取某一个点的poi信息。

实现步骤：

第一步：在index.html中引入高德地图相关api。根据具体项目的需求建立不同的项目获取不同key值

    

	<link rel="stylesheet" href="http://cache.amap.com/lbs/static/main1119.css"/>
	<script src="http://webapi.amap.com/maps?v=1.4.3&key=1d54cf0e4dac3ed6da30cbad7627dcdd&plugin=AMap.PlaceSearch"></script>
	<script src="http://webapi.amap.com/ui/1.0/main.js?v=1.0.11"></script>

第二步：在相应html中添加下拉框

<div class="col-sm-3 ">
      <input  id="pickerInput" class="form-control" [(ngModel)]="content" (ngModelChange)="change()" >
      <div style="color:white" id="poiResult"></div>
    </div>

第三步：相应ts中获取信息

declare var AMapUI: any;

  change() {
    let content = this.content;

    console.log(content);
    AMapUI.loadUI(['misc/PoiPicker'], function(PoiPicker) {

      var poiPicker = new PoiPicker({
          input: 'pickerInput',
          
      });

      poiPicker.on('poiPicked', function(poiResult) {


         var source = poiResult.source,
                poi = poiResult.item,
                info = {
                    source: source,
                    id: poi.id,
                    name: poi.name,
                    location: poi.location.toString(),
                    address: poi.address
                };

      });

  });


  }
