Displaying the sum

[11155]

I'm creating a very simple Rails application where I enter "First
number" and then "Second number" and get the result in the "Sum".

Those are some files:

show.html.erb: http://pastie.org/private/1cydign77xnijlrb7mjvng
_form.html.erb: http://pastie.org/private/narsz5oeuafahclqtvmwq

What do I want?

I just want the Sum to be DISPLAY the summation result automatically
after entering the first and second numbers, without having a text box
beside some.

I think it may be a HRML/CSS touch?

What should I do here?

Thanks.

If you want to populate the sum field with the result of first number +
second number, consider JavaScript.

Thanks Pale, cannot I use CSS for that. I'm actually not aware of
Javascript.

Do no not use CSS for this; CSS is for styling your page. If you're not
familiar with JavaScript, can I suggest you start here:

Got you Pale.

So, you mean that even I have the result, I cannot display it using CSS
since it is for styling?

I'll check Javascript then.

Thanks a lot.
