Hi Community!

How do I change the value of an application variable on the event onSubmit()?

I don't know if I can use javascript to modify application variables. I think I can't but I wanted to hear from the experts :-)

Thanks!

Ysais.

Actually, all local variables disappear once a page has been submitted. Also, what do you want to do if another user had submitted that page in the last hour? What about if the user had submitted another page in the last hour?

The gist of all this is that application variables might not be the best way to accomplish your goal.

Code running in a client (AKA JavaScript) can *NOT* change any values in
memory on the server or vice a versa.

If you want the client to communicate anything to the server it must use
some type of communication with it. The normal would be a HTTP request
either a normal get or post request or a JavaScript request object AKA AJAX.
