Upload Demonstrates General Performance Issues


Product Progress® Kendo UI® Upload for jQuery
Operating System Windows 10 64bit


The jQuery Upload demonstrates general performance issues.


When working in Opera, the following symptoms of incorrect behavior occur:

  • The success is fired when the file upload fails.
  • The server response cannot be accessed in the success event.
  • The success event fires before the upload is complete.


Turn off the Opera Dragonfly debugging tool because it interferes with the upload by firing an extra Load event for the iframe.
