Passing variables from CGI

[Guest_imported]

Hi,

Does anyone know if Javascript can be used to query a CGI script and then display the value returned by the CGI?

The easiest way is to use your CGI to render your HTML page including the necessary JavaScript variables.

If you absolutely have to do it dynamically without refreshing, you can use the trick of creating a zero-width frame, run the CGI in that frame (which returns a page with JavaScript variables defined), and use JavaScript to get parent.invisible_frame.document.variable.
