Some Javascript Help

Cassius · April 7, 2006

Hey, I'm working on this proxy rite now. It has one text box on it, and two buttons. One button puts the text box through base64 and displays the text in the text box, and the second button submits it. I wanted to make it so that their was only one button that would send it through the javascript function and then submit it, and I would like it to work if they press enter aswell. I've messed around w/ it alot, and get it to work, any help would be greatly appreciated. Here is the javascript/html I have so far..

P.S. If the forum messes up the format of the text, you can go to

http://rossk.org/php/html/test/shoppingcart-lastedit.php

to get the source. And thanks again.
