TrustedTypePolicy: createScript() method

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 createScript() method of the TrustedTypePolicy interface creates a TrustedScript object using a policy created by TrustedTypePolicyFactory.createPolicy().

Syntax

js
createScript(input)
createScript(input, args)

Parameters

input

A string containing the string to be sanitized by the policy.

args Optional

Additional arguments to be passed to the function represented by TrustedTypePolicy.

Exceptions

TypeError

Thrown if TrustedTypePolicy does not contain a function to run on the input.

In the below example a string containing a potentially risky script is used as the input for createScript(). The policy can sanitize this script before inserting it into an injection sink that could cause it to be executed.

const sanitized = scriptPolicy.createScript("eval('2 + 2')");
