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);
