                // process result
                // ...
            }

Server-Side

			
        function serverComputeAge(string name, int year)
        {
            int age = DateTime.Now.Year - year;
            return name + " is " + age + " years old.";
        }

Name and Date Of Birth parameters can be sent to the server in two ways:

Using AddParam method.
Using params parameter of post method.

See also AddParam/ResetParams tutorial.

In this example, you can add up to 10 parameters, and when doing the callback,
the server will return each of the parameters added on a new row.

To add a parameter, simply add the value in the second textbox and hit "AddParam" button.
To remove all the parameters added using AddParam method hit "ResetParams" button.

After adding the parameters, click "Callback now!" button to do a callback.
If you add 10 parameters, the callback is automatically performed.
