  • 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)

Parameter Name Type Required Description Platform Difference Description
type String 指定坐标系类型,可以是 wgs84 或 gcj02 微信小程序、抖音小程序
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('开启应用接收位置消息成功'),
  fail: err => console.error('开启应用接收位置消息失败:', err),
  complete: msg => console.log('调用开启应用接收位置消息 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.
