Hierarchy

Properties

AT_TARGET: number
BUBBLING_PHASE: number
CAPTURING_PHASE: number
NONE: number
altKey: boolean
bubbles: boolean

Returns true or false depending on how event was initialized. True if event goes through its target's ancestors in reverse tree order, and false otherwise.

button: number
buttons: number
cancelBubble: boolean

Deprecated

cancelable: boolean

Returns true or false depending on how event was initialized. Its return value does not always carry meaning, but true can indicate that part of the operation during which event was dispatched, can be canceled by invoking the preventDefault() method.

clientX: number
clientY: number
composed: boolean

Returns true or false depending on how event was initialized. True if event invokes listeners past a ShadowRoot node that is the root of its target, and false otherwise.

ctrlKey: boolean
currentTarget: null | EventTarget

Returns the object whose event listener's callback is currently being invoked.

dataTransfer: null | DataTransfer

Returns the DataTransfer object for the event.

defaultPrevented: boolean

Returns true if preventDefault() was invoked successfully to indicate cancelation, and false otherwise.

detail: number
dropAction: DropAction

The drop action supported or taken by the drop target.

Notes

At the start of each event, this value will be 'none'. During a 'lm-dragover' event, the drop target must set this value to one of the supported actions, or the drop event will not occur.

When handling the drop event, the drop target should set this to the action which was actually taken. This value will be reported back to the drag initiator.

eventPhase: number

Returns the event's phase, which is one of NONE, CAPTURING_PHASE, AT_TARGET, and BUBBLING_PHASE.

isTrusted: boolean

Returns true if event was dispatched by the user agent, and false otherwise.

metaKey: boolean
mimeData: MimeData

The mime data associated with the event.

Notes

This is mime data provided by the drag initiator. Drop targets should use this data to determine if they can handle the drop.

movementX: number
movementY: number
offsetX: number
offsetY: number
pageX: number
pageY: number
proposedAction: DropAction

The drop action proposed by the drag initiator.

Notes

This is the action which is preferred by the drag initiator. The drop target is not required to perform this action, but should if it all possible.

relatedTarget: null | EventTarget
returnValue: boolean

Deprecated

screenX: number
screenY: number
shiftKey: boolean
source: any

The source object of the drag, as provided by the drag initiator.

Notes

For advanced applications, the drag initiator may wish to expose a source object to the drop targets. That will be provided here if given by the drag initiator, otherwise it will be null.

srcElement: null | EventTarget

Deprecated

supportedActions: SupportedActions

The drop actions supported by the drag initiator.

Notes

If the dropAction is not set to one of the supported actions during the 'lm-dragover' event, the drop event will not occur.

target: null | EventTarget

Returns the object to which event is dispatched (its target).

timeStamp: number

Returns the event's timestamp as the number of milliseconds measured relative to the time origin.

type: string

Returns the type of event, e.g. "click", "hashchange", or "submit".

view: null | Window
which: number

Deprecated

x: number
y: number

Methods

  • Returns the invocation target objects of event's path (objects on which listeners will be invoked), except for any nodes in shadow trees of which the shadow root's mode is "closed" that are not reachable from event's currentTarget.

    Returns EventTarget[]

  • Parameters

    • keyArg: string

    Returns boolean

    Parameters

    • typeArg: string
    • Optional bubblesArg: boolean
    • Optional cancelableArg: boolean
    • Optional viewArg: null | Window
    • Optional detailArg: number

    Returns void

  • If invoked when the cancelable attribute value is true, and while executing a listener for the event with passive set to false, signals to the operation that caused event to be dispatched that it needs to be canceled.

    Returns void

  • Invoking this method prevents event from reaching any registered event listeners after the current one finishes running and, when dispatched in a tree, also prevents event from reaching any other objects.

    Returns void

  • When dispatched in a tree, invoking this method prevents event from reaching any objects other than the current object.

    Returns void
