But, in the case where you want javascript to process user entered data, or to provide additional information based on some user action, you have two options (that i can think of, there are probably more!):

1) have javascript create additional 'form' fields containing the info you want passed back to dtml/scripts (said form fields can then be processed as usual)

2) create a hidden iframe in your html page; use javascript to reload this page by building a url (with data parameters) which invokes a dtml/script routine. The dtml/script can process the parameters passed in the url and then pass whatever you want back to the client where your javascript can then interpret the response from the dtml/script. This is a nice way of communicating between the client and your zope site without the user seeing page reloads.

Or, as I've seen lately in a weird example, you can use JavaScript to write some value into a cookie and use something from within Zope to read that cookie value. Not saying that it would make sense everywhere. Regards, Sascha
