HTML <script> crossorigin Attribute

Last Updated : 23 Jul, 2025

The HTML <script> tag with the crossorigin attribute specifies how to handle fetching of external scripts. When set to "anonymous", it indicates that the script should be retrieved without sending user credentials.

Cross-Origin Resource Sharing(CORS) is a tool that allows web pages requesting for resources from another domain that is outside of their own domain. It is also used for managing cross-origin requests which is a request for a resource from an outside domain.

Syntax:

<script crossorigin="anonymous | use-credentials">

Attribute Values:

AttributeDescription
anonymousIt has a default value. It defines a CORS request will be sent without passing the credentials information.
use-credentialsA cross-origin request will be sent with credentials, cookies, and certificates

Note: This attribute is only valid for use if we try to fetch the resources from the third party domain. 

Example: In this example the HTML script tag with crossorigin attribute set to "anonymous" for loading my_script.js file. Button for submission included in the body.
