HTMLScriptElement: crossOrigin property

{{APIRef("HTML DOM")}} 

The crossOrigin property of the {{domxref("HTMLScriptElement")}}  interface reflects the {{Glossary("CORS", "Cross-Origin Resource Sharing")}}  settings for the script element. For classic scripts from other origins, this controls if full error information will be exposed. For module scripts, it controls the script itself and any script it imports. See CORS settings attributes for details.

Value

A string of a keyword specifying the CORS mode to use when fetching the resource. Possible values are:

• anonymous or an empty string ("")
  • : Requests sent by the {{domxref("HTMLScriptElement")}}  will use the cors {{domxref("Request.mode", "mode", "", "nocode")}}  and the same-origin {{domxref("Request.credentials", "credentials", "", "nocode")}}  mode. This means that CORS is enabled and credentials are sent if the resource is fetched from the same origin from which the document was loaded.
• use-credentials
  • : Requests sent by the {{domxref("HTMLScriptElement")}}  will use the cors {{domxref("Request.mode", "mode", "", "nocode")}}  and the include {{domxref("Request.credentials", "credentials", "", "nocode")}}  mode. All resources requests by the element will use CORS, regardless of which domain the fetch is from.

If the crossOrigin property is specified with any other value, it is the same as specifying it as the anonymous.

If the crossOrigin property is not specified, the resource is fetched without CORS (the no-cors {{domxref("Request.mode", "mode", "", "nocode")}}  and the same-origin {{domxref("Request.credentials", "credentials", "", "nocode")}}  mode).
