Help inserting Ruby script in HTML

In my HTML page, I simply have an input box and an output box.

The Ruby script I have simply extracts the value from the input box, calculates and needs to display the output in the output box.

How do I get this done in my HTML code?

Try using Ruby as your CGI back-end. Here is a simple overview of what Ruby with CGI might be. You can also delve into the intro given by the Pragmatic Programmers here. So fo example:

if your HTML contains a form that has the field someVal, then you can access it using Ruby's cgi as:

require 'cgi'
cgi = CGI.new
cgi['someVal']  »   ["whatever they sent in someVal"]

To make it even more interesting, without using any special frameworks, you can use Ruby's eruby so that you directly embed your Ruby in HTML :-).

Something like:

This text is <% a = 100; puts "#{a}% Live!" %>

Gives something like:

This text is 100% Live!

Try it out, I know you'll love what you learn...
