y 只读特性在 Gyroscope interface returns a double precision integer containing the angular velocity of the device along the its y axis.

If a feature policy blocks use of a feature it is because your code is inconsistent with the policies set on your server. This is not something that would ever be shown to a user. See Feature-Policy for implementation instructions.

句法

var y = gyroscope.y
					

值

A Number .

范例

The gyroscope is typically read in the Sensor.onreading event callback. In the example below this occurs sixty times a second.

let gyroscope = new Gyroscope({frequency: 60});
gyroscope.addEventListener('reading', e => {
  console.log("Angular velocety along the X-axis " + gyroscope.x);
  console.log("Angular velocety along the Y-axis " + gyroscope.y);
  console.log("Angular velocety along the Z-axis " + gyroscope.z);
});
gyroscope.start();
