Experimental: 這是一個實驗中的功能
此功能在某些瀏覽器尚在開發中,請參考兼容表格以得到不同瀏覽器用的前輟。

概要

DeviceMotionEvent 提供了網頁開發者關於裝置位置及旋轉方向改變時的速度資訊。

Warning: Currently, Firefox and Chrome does not handle the coordinates the same way. Take care about this while using them.

屬性

DeviceMotionEvent.acceleration (en-US) Read only
An object giving the acceleration of the device on the three axis X, Y and Z. Acceleration is expressed in m/s2.
DeviceMotionEvent.accelerationIncludingGravity (en-US) Read only
An object giving the acceleration of the device on the three axis X, Y and Z with the effect of gravity. Acceleration is expressed in m/s2.
DeviceMotionEvent.rotationRate (en-US) Read only
An object giving the rate of change of the device's orientation on the three orientation axis alpha, beta and gamma. Rotation rate is express in degrees per seconds.
DeviceMotionEvent.interval (en-US) Read only
A number representing the interval of time, in milliseconds, at which data is obtained from the device.

範例

window.addEventListener('devicemotion', function(event) {
  console.log(event.acceleration.x + ' m/s2');
});
