Just to be clear:

• Your javascript is executed by the user’s browser on the user’s laptop
• Your ASP.NET method is executed on your server

So, what you probably want to do is to send a message from the browser to the server saying “Hey, run this method and give me the result back”.

If you are doing traditional ASP.NET development (not ASP.NET MVC), I think the normal approach would be to create an ASPX page which, when requested, executes the method you want executed. Then, in your javascript you just need to request this page. To do this, you can use jQuery (either jQuery ajax, jQuery get or jQuery post).

You will need to download the jQuery library and include it in your page for this to work.

Give it a go and if you can’t get it to work, come back for more specific advice.

EDIT: You can also take a look at ASP.NET AJAX. The home page has a lot of tutorials and videos.
