161913、ionic + 高德地图定位

实例一：

var AMapArea=document.getElementById(‘amap‘);
    AMapArea.parentNode.style.height="100%";
    //$scope.AMapId=‘container‘;
    $scope.mapObj;//存放初始化的地图对象

      $scope.mapObj=new AMap.Map("container",{
        resizeEnable: true,
          zoom: 14,
          center: [116.39,39.9]
      });
    $scope.mapObj.plugin([‘AMap.Geolocation‘], function () {
      var geolocation = new AMap.Geolocation({
        enableHighAccuracy: true,//是否使用高精度定位，默认:true
        timeout: 10000,          //超过10秒后停止定位，默认：无穷大
        maximumAge: 0,           //定位结果缓存0毫秒，默认：0

        showButton: true,        //显示定位按钮，默认：true
        buttonPosition: ‘LB‘,    //定位按钮停靠位置，默认：‘LB‘，左下角
        buttonOffset: new AMap.Pixel(10, 20),//定位按钮与设置的停靠位置的偏移量，默认：Pixel(10, 20)
        showMarker: true,        //定位成功后在定位到的位置显示点标记，默认：true
        showCircle: true,        //定位成功后用圆圈表示定位精度范围，默认：true
        panToLocation: true,     //定位成功后将定位到的位置作为地图中心点，默认：true

            break;
        }
        // 如果获取经纬度时出错, 提示错误
        //toaster.pop(‘error‘,‘无法获取您的地理位置‘,‘请检查您是否禁止本应用获取您的当前位置‘);
        console.log(‘无法获取您的地理位置‘,‘请检查您是否禁止本应用获取您的当前位置‘);
        deferred.reject(error);
      });
      return deferred.promise;
    };

实例三、

        console.log(JSON.stringify(err));
        return;
      }
      //获取地理位置
      /*document.addEventListener("deviceready", function (success) {
        var posOptions = { timeout: 5000, enableHighAccuracy: false };
        $cordovaGeolocation
