TrustedTypePolicy: createScriptURL() method

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Note: This feature is available in Web Workers.

The createScriptURL() method of the TrustedTypePolicy interface creates a TrustedScriptURL object using a policy created by TrustedTypePolicyFactory.createPolicy().

Syntax

js
createScriptURL(input)
createScriptURL(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.

Return value

Exceptions

TypeError

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

Examples

In the below example a string containing the URL to an external resource is used as the input for createScriptURL(). The policy can check that this is an allowed URL before inserting it into an injection sink that could cause this external script to be executed.

js
const escaped = escapeURLPolicy.createScriptURL(
  "https://example.com/my-script.js",
);
