Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since October 2018.

Thuộc tính securitypolicyviolation is fired when a Content Security Policy is violated.

The event is fired trên phần tử when there is a violation of the CSP policy.

While HTML elements can technically be the target of the securitypolicyviolation event, in reality this event does not fire on them—for example, a blocked <img> source directly triggers this event on document as the target, instead of bubbling from the <img> element.
