How Do You Make A Javascript Calculator? - in a form

masugidsk8r
QUOTE(darran @ Feb 28 2007, 02:35 AM) *
With this do you mean you want to create everything from javascript or create a standard form using normal HTML tags and then making use of Javascript to actually compute the values the user enters in.

If I am not wrong, you are also trying to integrate an AJAX function into this form too? Since you want to have the fields where you type in the numbers and it gives you the answer. So after a user types in a value, it will compute automatically and display in the results field.


Actually this program wouldn't need to use AJAX, it shouldn't need to call a script to perform such a simple task. It can all be done in Javascript.
