Troubleshooting and debugging CORS

Detecting problems with CORS requires enabling the crossorigin attribute in the <script> tag.

Normal script tags will pass the least information to window.onerror for scripts that do not pass the standard CORS checks. To allow error logging for sites that use a separate domain for static media, several browsers have enabled the crossorigin attribute for scripts using the same definition as the standard crossorigin attribute for the <img> tag.
