uni.onAccelerometerChange(CALLBACK)

listen to the acceleration data at a frequency of 5 times/second. The listening to will automatically start after the interface is called. You can use uni.offAccelerometer to cancel the listening to.

CALLBACK return parameter

Parameter	Type	Instruction
x	Number	X axis
y	Number	Y axis
z	Number	Z axis

Tips

• To obtain acceleration information on the H5 side, it must be deployed on the https service. For local preview (localhost), the http protocol can still be used.

Example

uni.onAccelerometerChange(function (res) {
	console.log(res.x);
	console.log(res.y);
	console.log(res.z);
});

uni.offAccelerometerChange(CALLBACK)

Remove listening to the acceleration data.

uni.startAccelerometer(OBJECT)

Start listening to the acceleration data.
