The web video script I’m using has an Upload form that works successfully. Upon selecting “Upload” the page shows the Upload progress in % numbers up to 100%, then stays like this Upload Progress 100%" until the page redirects. I believe this is the line of code for the progress in % numbers:

PHP Code:
request.upload.onprogress = function (event) {
callback('Upload Progress ' Math.round(event.loaded 100) + "%");
How can I display “Please Wait” after it displays “Upload Progress 100%” 
Any help is appreciated.
