B4J Question File Upload with Websocket - show progress?

[JanPRO]

Hi,

currently I'am working with this WebApp example: http://basic4ppc.com:51042/websocket_with_fileupload/index.html

But I have a question: Is it possible to show the upload progress? And when not: Is there a alternative?

It is not possible to show the real progress. You can show a progress bar in indeterminate mode: https://jqueryui.com/resources/demos/progressbar/indeterminate.html

I have found a simple solution:

1.) Add this code in your Webscoket_Connected sub:

    ws.Eval($"
        $('#id').ajaxForm({
            uploadProgress: function(event, position, total, percentComplete) {
                b4j_raiseEvent("upload_progress",{"progress":percentComplete});
            }
        });"$,Null)

2.) Set the id of your form
3.) Get the progress:

Sub upload_progress(Params As Map)
    Dim Progress As Float = Params.Get("progress")
    Log(Progress)
End Sub
