The MouseEvent interface provides specific contextual
information associated with Mouse events.
The detail attribute inherited from UIEvent
indicates the number of times a mouse button has been pressed and
released over the same screen location during a user action. The
attribute value is 1 when the user begins this action and increments by 1
for each full sequence of pressing and releasing. If the user moves the
mouse between the mousedown and mouseup the value will be set to 0,
indicating that no click is occurring.
In the case of nested elements mouse events are always targeted at the most deeply nested element. Ancestors of the targeted element may use bubbling to obtain notification of mouse events which occur within its descendent elements.
The horizontal coordinate at which the event occurred relative to the origin of the screen coordinate system.
The vertical coordinate at which the event occurred relative to the origin of the screen coordinate system.
The horizontal coordinate at which the event occurred relative to the DOM implementation's client area.
The vertical coordinate at which the event occurred relative to the DOM implementation's client area.
Used to indicate whether the 'ctrl' key was depressed during the firing of the event.
Used to indicate whether the 'shift' key was depressed during the firing of the event.
Used to indicate whether the 'alt' key was depressed during the firing of the event. On some platforms this key may map to an alternative key name.
Used to indicate whether the 'meta' key was depressed during the firing of the event. On some platforms this key may map to an alternative key name.
During mouse events caused by the depression or release of a mouse
button, button is used to indicate which mouse button
changed state. The values for button range from zero to indicate
the left button of the mouse, one to indicate the middle button if present, and
two to indicate the right button. For mice configured for left handed use in which
the button actions are reversed the values are instead read from right to left.
Used to identify a secondary EventTarget related
to a UI event. Currently this attribute is used with the mouseover event to indicate the
EventTarget which the pointing device exited and with the mouseout event to indicate the
EventTarget which the pointing device entered.
The initMouseEvent method is used to initialize the value of a MouseEvent created through
the DocumentEvent interface. This method may only be called before the MouseEvent has
been dispatched via the dispatchEvent method, though it may be called multiple times during that
phase if necessary. If called multiple times, the final invocation takes precedence.
