    You will need to define a callback function which is invoked upon reciept of the response from the web method:

        $(document).ready(
    function test() {
        PageMethods.MyMethod(myMethodCallBackSuccess, myMethodCallBackFailed);
    })

    function myMethodCallBackSuccess(response) {
        alert(response);
    }

    function myMethodCallBackFailed(error) {
        alert(error.get_message());
    }

    You may also pass arguments to the method however these must always come before the success and failure callbacks.

    Note: you do not need to include the failed call back but it is available if required.
