Ruby CGI and Javascript

After a brief perusal of the Ruby CGI module documentation, it doesn't seem like there is a good way to generate Javascript from within it.

Due to the method_missing way that the CGI module handles HTML tags, however, it turns out to be quite simple: invoke cgi.script, passing all tag parameters as a hash, and pass the Javascript code as a string in the block:

  cgi.out {
    cgi.html {
      cgi.head {
        cgi.title {
          "Test"
        } +

        # Javascript library to include
        cgi.script( 'src' => 'dygraph-combined.js',
                    'type' => 'text/javascript') {
        }
      } +

      cgi.body {
        cgi.br +
        cgi.div( 'id' => 'graphdiv' ) +
        cgi.br +
        cgi.script( 'type' => 'text/javascript') {

          # Javascript to execute
          'g = new Dygraph(
                  document.getElementById("graphdiv"),
                  "Date,Temperature\n" +
                  "2008-05-07,75\n" +
                  "2008-05-08,70\n" +
                  "2008-05-09,80\n"
              );
          '
        }

      }

    }
