jquery - Remove selected file(s) before upload with Javascript

Question

Say I have a form that allows users to upload multiple images, which are appended with an option to remove them if they don't want to upload that particular photo.

Is it possible to remove the value from the files object of the one that they removed (e.g. didn't want to upload)?

Answer 1

FileList has no API to remove entries:

However you can reconstruct File uploader using XHR2 and AJAX and filter in content there. This implies doing XHR2 and AJAX upload and is not suitable for traditional <form> uploads.
