FileUpload: Disable buttons while uploading

[nattukan0713]

[x] bug report

Problem

Parallel upload is not considered, but it can be operated during upload. Therefore, the following problems occur.

• If you upload while uploading, the files to be uploaded are uploaded in duplicate.

  Reproduction procedure
  Click the upload button many times during the upload.

• The progress bar will be displayed more or less as the progress of multiple uploads is received in one state.

  Reproduction procedure (Advanced mode only)
  You can easily check by uploading large files in succession.

• When selecting a file during upload, the files parameter of onUpload(), onError() may be different from the file that was actually uploaded or failed to upload.

Defect Fixes

The current implementation only supports a single upload, so operations during upload are disabled.

Supplement

• If the auto property is true, uploading will start after file selection, so disable file selection during uploading.

• The files selected during upload are reset after the upload is complete, so the file selection feature during upload is useless.

• Since the function of the cancel button is to reset the selected state of the file and it is useless during uploading, the cancel button during uploading is disabled.

• You may confuse that you can cancel the upload if the Cancel button is enabled during the upload.
