how to stop invoke a method more than one times

How to stop invoking a method more than one times when this method has
submitted to server.My shopping system have methods to manage
But i found when i was submitting a method such as bill,i can still
flush or use keyboard in the browser to invoke this method many
times.This will make one cart corresponding many
bill,ship, i wish that one cart can only correspond one
bill,ship,pay...part.How do i make this reality?
Thank you

You could use JavaScript to disable the submit after the first time.

Use the :disable_with parameter in your form submit tag

Thank you!I will try it.It should be like that.
