属性

只读AT_TARGET

AT_TARGET: number

只读bubbles

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.

只读BUBBLING_PHASE

BUBBLING_PHASE: number

只读cancelable

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.

cancelBubble

cancelBubble: boolean

已被弃用

只读CAPTURING_PHASE

CAPTURING_PHASE: number

只读composed

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.

只读currentTarget

currentTarget: null | EventTarget

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

只读currentTime

currentTime: null | number

只读defaultPrevented

defaultPrevented: boolean

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

只读eventPhase

eventPhase: number

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

只读isTrusted

isTrusted: boolean

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

只读NONE

NONE: number

returnValue

returnValue: boolean

已被弃用

只读srcElement

srcElement: null | EventTarget

已被弃用

只读target

target: null | EventTarget

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

只读timelineTime

timelineTime: null | number

只读timeStamp

timeStamp: number

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

只读type

type: string

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

方法

composedPath

  • composedPath(): EventTarget[]

  • 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.

    返回 EventTarget[]

initEvent

  • initEvent(type, bubbles?, cancelable?): void

  • 参数

    • type: string
    • 可选bubbles: boolean
    • 可选cancelable: boolean

    返回 void

    已被弃用

preventDefault

  • preventDefault(): 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.

    返回 void

stopImmediatePropagation

  • stopImmediatePropagation(): 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.

    返回 void

stopPropagation

  • stopPropagation(): void

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

    返回 void
