Synchronous call to webservice

ScriptManager

Hi,

I have worked much in C# but bit new in ajax/webservice.

I know to call asmx webservice from script in sync/async manner using async attribute like...
eg.

$.ajax({ 
     type: "POST",
     url: "/Webservice/webservice1.asmx/SomeMethod",
     async: false,
     success: successMethod
});

but now I am calling the same using ajax script manager and from separate script file
eg.

function CallService(){
   var webServiceProxy = new testNamespace.Webservice.webservice1();
   //Code runs before calling webservice
   webServiceProxy.SomeMethod(successMethod);
   //codeLocation2
}

function successMethod(result) {
}

Now when I call the CallService Function the code @ codeLocation2 runs without waiting to the response from the webservice. So is that possible to wait for the result or successmethod execution before running codeLocation2 or need to write that into successMethod only.

In such case how to pass data from main function to success method.
Thanks in Advance.
