On my site users may upload zip files. These files may be quite big, so I need text to display, saying something like "Please wait while is file is beeing uploaded", when a user clicks the submit button to upload the file. Is it also possible to grey out the submit button when clicked?
The text needs to go away when the file is uploaded off course.
This is pretty simple functionality that you can achieve by reading up on forms and JavaScript (look for disabled). Same goes for showing and hiding text.
