How do I require a description, e.preventDefault() clears my current file

[danparker276]

on the OnUpload, I can validate that I have set a description textbox, but it will clear my current file selected.  Anyway to keep my current file?


        function onUpload(e) {

            var files = e.files;
            var description = $.trim($("#fileDescription").val());
            if (description.length < 1) {
                alert("Must have a description")
                e.preventDefault();

                    return;
            }

Hi Dan,


This behavior is by design - if the upload event is prevented, the file will be remove from the list. At the moment there is no workaround for this, so I would suggest you to reconsider the approach. Please excuse us if this is causing an inconvenience.

Anyway to disable the upload button until a description is entered in an input box?

Hi Dan,


At the moment I cannot suggest a workaround for this scenario, but I have passed the suggestion to the developers team, so we could improve this aspect of the Upload widget.

Please excuse us for the inconvenience caused.

Hello Dan,


We have pushed a fix for this behavior, which will be available in the first internal build after the official release from yesterday. It would allow disabling the widget in the select event handler, which will be useful in a combination with the async.autoUpload option set to false. This will not allow the user to start the file upload until a description is given (afterwards you should enable the widget again).

I hope this information helps. Have a great day!
