Properties

Property	Type	Description
`target` Read only	`EventTarget`	The element underneath the element being dragged.
`type` Read only	`DOMString`	The type of event.
`bubbles` Read only	`Boolean`	Whether the event normally bubbles or not
`cancelable` Read only	`Boolean`	Whether the event is cancellable or not?
`view` Read only	`WindowProxy`	`document.defaultView` (`window` of the document)
`detail` Read only	`long` (`float`)	0.
`dataTransfer`	DataTransfer	The data that underlies a drag-and-drop operation, known as the drag data store. Read only mode
`currentTarget` Read only	EventTarget	The node that had the event listener attached.
`relatedTarget` Read only	EventTarget	For `mouseover`, `mouseout`, `mouseenter` and `mouseleave` events: the target of the complementary event (the `mouseleave` target in the case of a `mouseenter` event). `null` otherwise.
`screenX` Read only	long	The X coordinate of the mouse pointer in global (screen) coordinates.
`screenY` Read only	long	The Y coordinate of the mouse pointer in global (screen) coordinates.
`clientX` Read only	long	The X coordinate of the mouse pointer in local (DOM content) coordinates.
`clientY` Read only	long	The Y coordinate of the mouse pointer in local (DOM content) coordinates.
`button` Read only	unsigned short	The button number that was pressed when the mouse event was fired: Left button=0, middle button=1 (if present), right button=2. For mice configured for left handed use in which the button actions are reversed the values are instead read from right to left.
`buttons` Read only	unsigned short	The buttons being pressed when the mouse event was fired: Left button=1, Right button=2, Middle (wheel) button=4, 4th button (typically, "Browser Back" button)=8, 5th button (typically, "Browser Forward" button)=16. If two or more buttons are pressed, returns the logical sum of the values. E.g., if Left button and Right button are pressed, returns 3 (=1 \| 2). More info.
`mozPressure` Read only	float	The amount of pressure applied to a touch or tabdevice when generating the event; this value ranges between 0.0 (minimum pressure) and 1.0 (maximum pressure).
`ctrlKey` Read only	boolean	`true` if the control key was down when the event was fired. `false` otherwise.
`shiftKey` Read only	boolean	`true` if the shift key was down when the event was fired. `false` otherwise.
`altKey` Read only	boolean	`true` if the alt key was down when the event was fired. `false` otherwise.
`metaKey` Read only	boolean	`true` if the meta key was down when the event was fired. `false` otherwise.
