Hi there peacemaker1820, What exactly are you trying to do? There is an important distinction between what is happening client side i.e. Javascript, and what is happening inside a CGI application, which happens server side. It could be that you are using ActiveState's perlscript and both Perl and Javascript are happening client side. But, I assume that your Perl is running server side. Note, for Javascript to call a CGI application, it does this by invoking a new URL. This causes the browser to bring up a new page, without passing back a return value, because you are not returning into the Javascript. One possibility though is to use frames. The new URL is loaded into a different target frame, and the new page for this frame contains some Javascript to call a function in your original frame to signify completion. hth --rW	[reply]

Have a look at the Javascript modules on CPAN: Javascript Perl extension for executing embedded JavaScript Data::JavaScript Perl extension for dumping structures into JavaScript Data::JavaScript::LiteObject Perl package to provide lightweight data dumping -- Check out my Perlmonks Related Scripts like framechat, reputer, and xNN.

You could use a framework like OpenThought: OpenThought is a powerful and flexible web application environment. OpenThought applications are different from other web applications in that all communication between the browser and the server is performed in the background. This gives a browser the ability to receive data from the server without ever reloading the currently loaded document. Data received can be displayed automatically on the existing page, can access JavaScript functions and variables, and can load new pages. Additionally, OpenThought completely manages all of your session data for you. These features give the look and feel of a full-blown application instead of just an ordinary Web page. I've not ever used it, but I have done a similar thing, basically using a hidden frame and javascript. You call a cgi script which returns javascript code to do things. Hope this helps.. gav^	[reply]
