This code is just to give you an idea of what I want.

No, you would need to do a post back to the server to accomplish this.

not directly. the javascript code is executed by the browser, ie on the computer of the visitor of your page, whereas the asp code is executed on the server. ways exist to mix the two - you might want to read up on AJAX (asynchronous javascript) which is basically all about getting the client-side to update based on server-side functionality without an actual reload.

You could use javascript to call a web service (.asmx) on the server and return a result. It is easy to do and probably sounds more daunting than the actual work involved.

Take a look at "jQuery, AJAX, and ASMX" for a tutorial to get you started. It is easy to write a simple "Hello World" web service and it is definitely worth the effort to learn more about making AJAX calls to the server.

It's also worth looking at WCF. There are some good posts on SO to look at:
