Possible to prevent upload? · Issue #848 · FineUploader/fine-uploader · GitHub

Hey there,

I have auto-upload disabled to give the user a chance to input a name for each file before upload. If the name is not unique — a check I do with an XHR request in onSubmit — I'd like to prevent the file from being uploaded until the name is unique (checked on keyup). I tried returning false in onUpload, but that doesn't seem to be supported, as the file is still uploaded. I know it's possible to prevent a file from being added, but that doesn't really help in this case. I'd like the file to be added, but prevent upload. Can you think of a way I can accomplish this flow?

I'm using v3.3 of the jQuery plugin.

Love the work you're doing — thanks!
