function listener

Listener function for acceleration data events

parameter

Object res

Parameter	Type	Description
x	Number	X-axYes
y	Number	Y-axYes
z	Number	Z axYes

Tips

• The H5 terminal needs to be deployed on the https service to obtain the acceleration information, and the local preview (localhost) can still use the http protocol.

example

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

uni.offAccelerometerChange(CALLBACK)

Cancel listening to acceleration data.
