The securitypolicyviolation event is fired when a Content Security Policy is violated in a worker.

The handler can be assigned using the onsecuritypolicyviolation event handler property (but note that this replaces other event listeners added using onsecuritypolicyviolation, if any) or using EventTarget.addEventListener().

Syntax

Use the event name in addEventListener():

addEventListener("securitypolicyviolation", (event) => { })

Alternatively, assign to the event handler property of the interface:

onsecuritypolicyviolation = (event) => { }

Event type

A SecurityPolicyViolationEvent. Inherits from Event.

Examples

The code below shows how you might add an event handler function using the onsecuritypolicyviolation event handler property (but note that this replaces other event listeners added using onsecuritypolicyviolation, if any) or call addEventListener() method.

self.onsecuritypolicyviolation = (e) => {
  // Handle SecurityPolicyViolationEvent e here
};

self.addEventListener("securitypolicyviolation", (e) => {
  // Handle SecurityPolicyViolationEvent e here
});
