TrustedScript
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 TrustedScript interface of the Trusted Types API represents a string with an uncompiled script body that a developer can insert into an injection sink that might execute the script. These objects are created via TrustedTypePolicy.createScript() and therefore have no constructor.
The value of a TrustedScript object is set when the object is created and cannot be changed by JavaScript as there is no setter exposed.
Instance methods
TrustedScript.toJSON()-
Returns a JSON representation of the stored data.
TrustedScript.toString()-
A string containing the sanitized script.
Examples
The constant sanitized is an object created via a Trusted Types policy.
const sanitized = scriptPolicy.createScript("eval('2 + 2')");
console.log(sanitized); /* a TrustedScript object */
