SecurityPolicyViolationEvent.sample

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The sample read-only property of the SecurityPolicyViolationEvent interface is a DOMString representing a sample of the resource that caused the violation.

Syntax

let sample = violationEventInstance.sample;

Value

A DOMString containing a sample of the resource that caused the violation, usually the first 40 characters. This will only be populated if the resource is an inline script, event handler, or style — external resources causing a violation will not generate a sample.

Example

document.addEventListener("securitypolicyviolation", (e) => {
  console.log(e.sample);
});
