Interface PageTransitionEvent

The PageTransitionEvent is fired when a document is being loaded or unloaded.

interface PageTransitionEvent {
    AT_TARGET: number;
    BUBBLING_PHASE: number;
    CAPTURING_PHASE: number;

    isTrusted: boolean;
    persisted: boolean;
    returnValue: boolean;
    srcElement: null | EventTarget;

ReadonlyAT_TARGET

AT_TARGET: number

ReadonlyBUBBLING_PHASE

BUBBLING_PHASE: number

ReadonlyCAPTURING_PHASE

CAPTURING_PHASE: number

ReadonlyNONE

NONE: number

Readonlybubbles

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.

cancelBubble

cancelBubble: boolean

Deprecated

Readonlycancelable

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.

Readonlycomposed

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.

ReadonlycurrentTarget

currentTarget: null | EventTarget

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

ReadonlydefaultPrevented

defaultPrevented: boolean

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

ReadonlyeventPhase

eventPhase: number

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

ReadonlyisTrusted

isTrusted: boolean

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

Readonlypersisted

persisted: boolean

For the pageshow event, returns false if the page is newly being loaded (and the load event will fire). Otherwise, returns true.

For the pagehide event, returns false if the page is going away for the last time. Otherwise, returns true, meaning that (if nothing conspires to make the page unsalvageable) the page might be reused if the user navigates back to this page.

Things that can cause the page to be unsalvageable include:

The user agent decided to not keep the Document alive in a session history entry after unload Having iframes that are not salvageable Active WebSocket objects Aborting a Document

returnValue

returnValue: boolean

Deprecated

ReadonlysrcElement

srcElement: null | EventTarget

Deprecated

Readonlytarget

target: null | EventTarget

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

ReadonlytimeStamp

timeStamp: number

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

Readonlytype

type: string

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

Methods

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.

    Returns EventTarget[]

initEvent

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

  • Parameters

    • type: string
    • Optionalbubbles: boolean
    • Optionalcancelable: boolean

    Returns void

    Deprecated

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.

    Returns 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.

    Returns void

stopPropagation

  • stopPropagation(): void

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

    Returns void
