TrustedScriptURL
Baseline
2026
Newly available
Since February 2026, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.
Note: This feature is available in Web Workers.
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.
Instance methods
TrustedScriptURL.toJSON()-
Returns a JSON representation of the stored data.
TrustedScriptURL.toString()-
A string containing the sanitized URL.
Examples
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 */
