插件列表

来源入高德地图开发平台

问题解决：

1. 未加安全秘钥

解决方法：

 <!-- 高德地图js插件-->
  <script type="text/javascript">
    window._AMapSecurityConfig = {
      securityJsCode: '安全密钥jscode',
    }
  </script>

必须在key值前面写

2. TypeError: __WEBPACK_IMPORTED_MODULE_0_AMap___default.a.DistrictSearch is not a constructor
   

​ 解决方法： 没有加载插件，在key值后面加入

 <script type="text/javascript"
    src="https://webapi.amap.com/maps?v=1.4.15&key=key值&plugin=AMap.DistrictSearch,AMap.Geocoder,AMap.DistrictLayer,AMap.AutoComplete,AMap.PlaceSearch">
