Because of normal browser security limitations, you cannot use JavaScript to save a file to the desktop from a web browser so in short the answer is no you can't.

I have made the assumption you are generating text to be saved to a file in the Web Browser. What you can do is submit that text to your web server and have your web server send the text back as the HTTP response but setting the following HTTP Header...

Content-Disposition: attachment; filename=<file name.ext>

... which will force the Save As dialog, instead of the browser rendering it on screen.

Hope that helps you...
