TrustedScriptURL

The TrustedScriptURL interface of the Trusted Types API represents a string that a developer can insert into an injection sink that will parse it as a URL of an external script. These objects are created via TrustedTypePolicy.createScriptURL() and therefore have no constructor.

The value of a TrustedScriptURL object is set when the object is created and cannot be changed by JavaScript as there is no setter exposed.

TrustedScriptURL.toJSON()

Returns a JSON representation of the stored data.

TrustedScriptURL.toString()

A string containing the sanitized URL.

The constant sanitized is an object created via a Trusted Types policy.

const sanitized = scriptPolicy.createScriptURL("https://example.com/my-script.js");
console.log(sanitized;) /* a TrustedScriptURL object */
