Prevent submitting the page twice!

[Gaurav Jain]

I want to prevent the user from submitting the page twice either by hitting F5 or browser refresh button or by clicking submit again.
is there a way in javascript which can take care of all the possible scenarios of submitting the page again?

I'm not sure about a javascript solution, but what happens if the end user has javascript turned off?

In a web app you should try to make no assumptions about client side validation of input or requests. You should probably try to set some flag with the users session. Just an idea off the top of my head.

JavaScript can not block all of the methods. The best solution is to handle it on the server side.

I talked about it here awhile back:
