Notice

This method will continuously monitor the changes of the geographic location information. It is recommended to call the uni.stopLocationUpdate method to cancel the monitoring after you do not need to monitor the changes of the geographic location information.
微信小程序若使用该接口，需要在 app.json 中进行声明，否则将无法正常使用该接口，详情
抖音小程序调用此 API 需要申请高精度权限，具体信息见高精度定位运营规范。

Example

uni.onLocationChange(function (res) {
	console.log('纬度：' + res.latitude);
	console.log('经度：' + res.longitude);
});

# uni.offLocationChange(FUNCTION CALLBACK)

移除实时地理位置变化事件的监听函数。

success	Function	No	Callback function for successful interface call
fail	Function	No	Callback function for interface call failure
complete	function	No	The callback function of the end of the interface call (the call will be executed if the call succeeds or fails)
needFullAccuracy	Boolean	No	For the new features of iOS14/Android12 and above, this parameter is ignored in other cases. By default, the host returns precise positioning information if it is precise positioning. Passing in true will force the use of precise positioning information. If the precise positioning permission is not available for iOS14/Android12 and above, the precise positioning authorization popup will pop up.	Baidu MiniApp

Example

uni.startLocationUpdate({
  success: res => console.log('开启小程序接收位置消息成功'),
  fail: err => console.error('开启小程序接收位置消息失败：', err),
  complete: msg => console.log('调用开启小程序接收位置消息 API 完成')
});

# uni.stopLocationUpdate(OBJECT)

Turn off the monitoring of real-time location changes, and both the front and back will stop receiving messages.
