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); });
