Here’s what we do:
- Patch existing jquery.form plugin or update to a newer version.
- Test affected modules on Chrome version 83.0.4103.61
- Test jquery.form functionality on all browsers.
This problem seems to go away if we ensure the iframe jquery.form uses for the upload has an src of about:blank rather than javascript:false, which has been used for https requests for years.
If you’re facing a problem with AJAX file upload on Chrome version 83.0.4103.61, feel free to contact Infomaze, we have helped resolve the same issue for various clients.
