Jquery progress bar

Jquery progress bar

Hi,
I am new to Jquery.
I have a web page that takes some input from the user and then deletes documents(around 1 lakhs) from the database.
Currently when the user clicks on submit,the request goes to the servlet and the servlet calls the java files.
However when the user clicks on submit...The pages goes blank(Since the request is now moved to servlet)..
What is want is to stay on the current page and open a progress bar showing the status of how many documents has been deleted and disable user intervention when the progress bar is running.

Need help on how this can be achieved.

Thanks in Advance :)
