Properties

Property Type Access Description
BlockedURI string get A string representing the URI of the resource that was blocked because it violates a policy.
ColumnNumber int? get The column number in the document or worker at which the violation occurred.
Disposition string get Indicates how the violated policy is configured to be treated by the user agent. This will be "enforce" or "report".
DocumentURI string get A string representing the URI of the document or worker in which the violation was found.
EffectiveDirective string get A string representing the directive whose enforcement uncovered the violation.
LineNumber int? get The line number in the document or worker at which the violation occurred.
OriginalPolicy string get A string containing the policy whose enforcement uncovered the violation.
Referrer string? get A string representing the URL for the referrer of the resources whose policy was violated, or null.
Sample string? get A string representing 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.

StatusCode int get A number representing the HTTP status code of the document or worker in which the violation occurred.
ViolatedDirective string get A string representing the directive whose enforcement uncovered the violation.

Examples

SpawnDev.SpawnJS Mapping Note: The JavaScript examples below show the standard Web API usage. In SpawnDev.SpawnJS, the same API is available with C# conventions:

  • Properties and methods use PascalCase (e.g., readyState becomes ReadyState)
  • Events use ActionEvent with +=/-= (e.g., addEventListener("click", fn) becomes OnClick += handler)
  • Async methods return Task<T> instead of Promise<T>
  • Objects should be disposed with using statements
  • Access via JS.Get<SecurityPolicyViolationEvent>(...) or constructor new SecurityPolicyViolationEvent(...)
document.addEventListener("securitypolicyviolation", (e) => {
  console.log(e.blockedURI);
  console.log(e.violatedDirective);
  console.log(e.originalPolicy);
});
