调用，必须封装的closeContinuousLocation才生效

javascript 复制代码

      () => {
        console.log('定位已开启');
        this.calculateDrivingInfo(null)
      },
      (location) => {
        console.log('位置更新: ' + JSON.stringify(location));
       
      }
    );
  }

  /**
   * 关闭持续定位
   */
  ClosedContinuosLocation() {
    console.log(' 定位关闭 ClosedContinuosLocation')
    // 关闭持续定位
    this.locationService.closeContinuousLocation(
      () => {
        console.log('定位已关闭');
      }
    );
