class MouseEvent |
|
|
|
|
|
|
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. |
|
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. |
|
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. |
|
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. Parameters
typeArg - Specifies the event type. canBubbleArg - Specifies whether or not the event can bubble. cancelableArg - Specifies whether or not the event's default action can be prevented. viewArg - Specifies the Event's AbstractView. detailArg - Specifies the Event's mouse click count. screenXArg - Specifies the Event's screen x coordinate screenYArg - Specifies the Event's screen y coordinate clientXArg - Specifies the Event's client x coordinate clientYArg - Specifies the Event's client y coordinate ctrlKeyArg - Specifies whether or not control key was depressed during the Event. altKeyArg - Specifies whether or not alt key was depressed during the Event. shiftKeyArg - Specifies whether or not shift key was depressed during the Event. metaKeyArg - Specifies whether or not meta key was depressed during the Event. buttonArg - Specifies the Event's mouse button. relatedTargetArg - Specifies the Event's related EventTarget. |
|
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. |
|
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 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. |
|
Used to indicate whether the 'shift' key was depressed during the firing of the event. |
