Bubbles | Yes |
---|---|
Cancelable | No |
Interface | SecurityPolicyViolationEvent |
Event handler property | onsecuritypolicyviolation |
The event is fired on the element that violates the policy and bubbles.
It is normally handled by an event handler on the Window
or Document
object.
The handler can be assigned using the GlobalEventHandlers.onsecuritypolicyviolation
property or using EventTarget.addEventListener()
.
Examples
The code below shows how you might add an event handler function using the onsecuritypolicyviolation
global event handler property or addEventListener()
on the top level Window
(you could use exactly the same approach on Document
).
window.onsecuritypolicyviolation = function(e) {
// Handle SecurityPolicyViolationEvent e here
};
window.addEventListener("securitypolicyviolation", (e) => {
// Handle SecurityPolicyViolationEvent e here
});
