You can use jquery ajax methods for more information refer below link..

Thanks for the reply but the scenario is about using raw javascript only as well ablove mentioned links doesnt provide any explanation about getting value from particular function.

I use AJAX frequently, although calling php functions. The way an response is typically returned is via an ECHO statement - which is analogous to your response.write().

As for page-load: the reason I use AJAX are twofold. (1) to do SQL queries on the server side; (2) to not have to reload the page with the new data, but only a selected part.*

* 99% of the time, this is innerHTML, but on occasion, I'll rewrite an actual javaScript. This will not execute - so one plays with updating the content of a javaScript function that is already on the page and the call to the function is part of the AJAX script so it will be executed.
