What you did is call the JS from the server side. I think what you are asking for is the opposite. How do you get JS to pass to the server side? Use jQuery.ajax() to call your webservice. Server side code executes and then the whole packet is sent to the client and then JS executes so there is no way for the server to wait for JS to execute. http://api.jquery.com/jQuery.ajax/

Solution 1

Store the result in a hidden field in the JavaScript function and access the hidden field from the server (after a postback).

your suggestion are nearing my answer but at first postback the default value of hidden field is returned istead of stored data from client side
