SecurityPolicyViolationEvent

The SecurityPolicyViolationEvent interface inherits from Event, and represents the event object of a securitypolicyviolation event sent on an Element, Document, or worker when its Content Security Policy (CSP) is violated.

Methods​

composedPath()​

composedPath(): EventTarget[];

The composedPath() method of the Event interface returns the event's path which is an array of the objects on which listeners will be invoked. This does not include nodes in shadow trees if the shadow root was created with its ShadowRoot.mode closed.

MDN Reference

Returns​

EventTarget[]

Inherited from​

Event.composedPath

initEvent()​

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

The Event.initEvent() method is used to initialize the value of an event created using Document.createEvent().

Parameters​

ParameterType
typestring
bubbles?boolean
cancelable?boolean

Returns​

void

Deprecated​

MDN Reference

Inherited from​

Event.initEvent

preventDefault()​

preventDefault(): void;

The preventDefault() method of the Event interface tells the user agent that the event is being explicitly handled, so its default action, such as page scrolling, link navigation, or pasting text, should not be taken.

MDN Reference

Returns​

void

Inherited from​

Event.preventDefault

stopImmediatePropagation()​

stopImmediatePropagation(): void;

The stopImmediatePropagation() method of the Event interface prevents other listeners of the same event from being called.

MDN Reference

Returns​

void

Inherited from​

Event.stopImmediatePropagation

stopPropagation()​

stopPropagation(): void;

The stopPropagation() method of the Event interface prevents further propagation of the current event in the capturing and bubbling phases. It does not, however, prevent any default behaviors from occurring; for instance, clicks on links are still processed. If you want to stop those behaviors, see the preventDefault() method. It also does not prevent propagation to other event-handlers of the current element. If you want to stop those, see stopImmediatePropagation().

Returns​

void

Inherited from​

Event.stopPropagation

Properties​

AT_TARGET​

readonly AT_TARGET: 2;

Inherited from​

Event.AT_TARGET

blockedURI​

readonly blockedURI: string;

The blockedURI read-only property of the SecurityPolicyViolationEvent interface is a string representing the URI of the resource that was blocked because it violates a Content Security Policy (CSP).

MDN Reference

bubbles​

readonly bubbles: boolean;

The bubbles read-only property of the Event interface indicates whether the event bubbles up through the DOM tree or not.

MDN Reference

Inherited from​

Event.bubbles

BUBBLING_PHASE​

readonly BUBBLING_PHASE: 3;

Inherited from​

Event.BUBBLING_PHASE

cancelable​

readonly cancelable: boolean;

The cancelable read-only property of the Event interface indicates whether the event can be canceled, and therefore prevented as if the event never happened.

MDN Reference

Inherited from​

Event.cancelable

cancelBubble​

cancelBubble: boolean;

The cancelBubble property of the Event interface is deprecated. Use Event.stopPropagation() instead. Setting its value to true before returning from an event handler prevents propagation of the event. In later implementations, setting this to false does nothing. See Browser compatibility for details.

Event.cancelBubble

CAPTURING_PHASE​

readonly CAPTURING_PHASE: 1;

Inherited from​

Event.CAPTURING_PHASE

columnNumber​

readonly columnNumber: number;

The columnNumber read-only property of the SecurityPolicyViolationEvent interface is the column number in the document or worker script at which the Content Security Policy (CSP) violation occurred.

MDN Reference

composed​

readonly composed: boolean;

The read-only composed property of the Event interface returns a boolean value which indicates whether or not the event will propagate across the shadow DOM boundary into the standard DOM.

MDN Reference

Inherited from​

Event.composed

currentTarget​

readonly currentTarget: EventTarget | null;

The currentTarget read-only property of the Event interface identifies the element to which the event handler has been attached.

MDN Reference

Inherited from​

Event.currentTarget

defaultPrevented​

readonly defaultPrevented: boolean;

The defaultPrevented read-only property of the Event interface returns a boolean value indicating whether or not the call to Event.preventDefault() canceled the event.

MDN Reference

Inherited from​

Event.defaultPrevented

disposition​

readonly disposition: SecurityPolicyViolationEventDisposition;

The disposition read-only property of the SecurityPolicyViolationEvent interface indicates how the violated Content Security Policy (CSP) is configured to be treated by the user agent.

MDN Reference

documentURI​

readonly documentURI: string;

The documentURI read-only property of the SecurityPolicyViolationEvent interface is a string representing the URI of the document or worker in which the Content Security Policy (CSP) violation occurred.

MDN Reference

effectiveDirective​

readonly effectiveDirective: string;

The effectiveDirective read-only property of the SecurityPolicyViolationEvent interface is a string representing the Content Security Policy (CSP) directive that was violated.

MDN Reference

eventPhase​

readonly eventPhase: number;

The eventPhase read-only property of the Event interface indicates which phase of the event flow is currently being evaluated.

MDN Reference

Inherited from​

Event.eventPhase

isTrusted​

readonly isTrusted: boolean;

The isTrusted read-only property of the Event interface is a boolean value that is true when the event was generated by the user agent (including via user actions and programmatic methods such as HTMLElement.focus()), and false when the event was dispatched via EventTarget.dispatchEvent(). The only exception is the click event, which initializes the isTrusted property to false in user agents.

MDN Reference

Inherited from​

Event.isTrusted

lineNumber​

readonly lineNumber: number;

The lineNumber read-only property of the SecurityPolicyViolationEvent interface is the line number in the document or worker script at which the Content Security Policy (CSP) violation occurred.
