complete the function
1 After all the data handling, the actual
Ajax request is made. The form data, represented
by the variable values, is used as
the only argument to the send() method.
(See extra bits on page 83.)
2 Finally, the function returns a value of false to
tell the Web browser not to actually submit the form
(since Ajax is handling the form submission).
Save this fi le as add_employee.js
and place it in the same directory on
your Web server as every other fi le.

} // End of anonymous function.
} // End of DOM check.
} // End of ajax IF.
} // End of init() function.
