This is 80% a JavaScript question that isn't really related to ASP, at all.

The only part that is ASP-related is that the JS code will use AJAX to connect back to your ASP server so that ASP can do the query and return the data back to JS.

Look here:

This part is 100% JavaScript. Nothing at all to do with ASP.
