Ajax call does not work

$('#loginbtn').click(function() {
            var userName = document.getElementById('uid').value;
            var password = document.getElementById('pwd').value;

            $.ajax({
                type: "POST",
                url: "/LoginNew.aspx/Authenticate",
                data: "{ 'userName': '" + userName + "' ,'password': '" + password + "' }",
                async: false;
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: a(),
                error: function(e) {
                    alert(e.valueOf());
                }
            });

         alert("test");
            function a() {
                window.location.href = "Login.aspx";
            }
        });

As I have accepted the answer its goes to the server side code authenticates user and control passes to "a" function but it does not display login.aspx page...Any clues?

The JSON you are generating is invalid. Don't try generating JSON by hand, use an JSON library.

JSON.stringify({ userName: userName, password: password })

You are calling a() instead of assigning a as the success handler. Remove the () if you want to assign the function instead of its return value.

it should be

$('#loginbtn').click(function() {
    var userName = document.getElementById('uid').value;
    var password = document.getElementById('pwd').value;

    $.ajax({
        type : "POST",
        url : "/LoginNew.aspx/Authenticate",
        data : { 
            userName: userName ,
            password: password 
        },
        async : false, // not ; need to use ,
        contentType : "application/json; charset=utf-8",
        dataType : "json",
        success : a, // pass the callback reference, don't invoke it
        error : function(e) {
            alert(e.valueOf());
        }
    });

    alert("test");
    function a() {
        window.location.href = "Login.aspx";
    }
});
