Constructor
Variables
An object giving the acceleration of the device on the three axis X, Y and Z. Acceleration is expressed in m/s2.
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.
A number representing the interval of time, in milliseconds, at which data is obtained from the device.
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.
Methods
Inherited Variables
Defined by Event
A Boolean indicating whether the event bubbles up through the DOM or not.
A Boolean indicating whether the event is cancelable.
A reference to the currently registered target for the event. This is the object to which the event is currently slated to be sent to; it's possible this has been changed along the way through retargeting.
Indicates whether or not event.preventDefault() has been called on the event.
Indicates which phase of the event flow is being processed.
The explicit original target of the event (Mozilla-specific).
Indicates whether or not the event was initiated by the browser (after a user click for instance) or by a script (using an event creation method, like event.initEvent)
The original target of the event, before any retargetings (Mozilla-specific).
A reference to the target to which the event was originally dispatched.
The time at which the event was created, in milliseconds. By specification, this value is time since epoch, but in reality browsers' definitions vary; in addition, work is underway to change this to be a DOMHighResTimeStamp instead.
The name of the event (case-insensitive).
Inherited Methods
Defined by Event
Initializes the value of an Event created. If the event has already being dispatched, this method does nothing.
Cancels the event (if it is cancelable).
For this particular event, no other listener will be called. Neither those attached on the same element, nor those attached on elements which will be traversed later (in capture phase, for instance)
Stops the propagation of events further along in the DOM.
