Does the page need to be updated in response?

If you can ensure the javascript makes whatever changes in the page indicate a post happened, then you don't really need a return. It's flying without a net as far as user feedback ... but I guess you can return something on an error and just accepted valid posts silently. Hmm, interesting idea. === Implicitly condoning stupidity since 2001.

What's wrong with this: \n<html>\n<head>\n <script language="javascript">\n<!-- \n function update_page(){\n // do stuff to the page to indicate submission\n }\n// -->\n </script>\n<body>\n<form name="nullform" action="submit_handler.cgi" method="POST">\n <input name="foo">\n <a href="javascript:document.nullform.submit(); update_page()">Link text</a>\n</form>\n</body>\n</html>\n As long as 'submit_handler.cgi doesn't generate a return, the browser doesn't reload anything. The 'update_page' function handles user feedback, unless there is a problem with the submission that javascript can't handle in which case there is a return that reloads the page. === Implicitly condoning stupidity since 2001.

The main part of the page was the user interface and was composed by the JavaScript library. When the user made an update, the JavaScript validated the entries and sent the result to the server, the response from the server was essentially a set of JavaScript variable assignments with a call into the library code in the left part of the page. The assignments would happen and the library call would cause the user interface part of the page to be redrawn. Does that explanation make sense? Does it fit your requirements? Have fun, Carl Forde
