MouseEvent.mozInputSource - Web APIs 编辑

Non-standard

This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The MouseEvent.mozInputSource read-only property on MouseEvent provides information indicating the type of device that generated the event. This lets you, for example, determine whether a mouse event was generated by an actual mouse or by a touch event (which might affect the degree of accuracy with which you interpret the coordinates associated with the event).

Syntax

var source = instanceOfMouseEvent.mozInputSource;

Return value

The following values are possible.
