validating the form is not working

my form validation does not firing...if i try to submit this form without entering anything then it should validate but in this case it does accept the form.

<script src="Scripts/jquery-1.4.4.min.js" type="text/javascript"></script>
<script src="Scripts/jquery.validate.min.js" type="text/javascript"></script>

<script>
    $(document).ready(function () {
        $("#register").click(function (event) {
            // validate the comment form when it is submitted  
            // validate signup form on keyup and submit
            $("#form1").validate({
                rules: {
                    firstname: "required",
                    lastname:开发者_运维技巧 "required",
                    //city: "required",
                    state: "required",
                    country: "required"
                },
                messages: {
                    firstname: "Please enter your firstname",
                    lastname: "Please enter your lastname",
                    //city: "Please enter a valid email address",
                    country: "Please select your country"
                }
            });
            $("#form1").validate({
                submitHandler: PostData
            });


            function PostData() {

                $.ajax(url, { Id: '1' },
                       function (data, textStatus) {
                           //alert(textStatus);
                       });

The .validate should be done once the document is ready, not on the click of the button. So take it out from there.

e.g.

$(document).ready(function () {
    $("#form1").validate({
            rules: {
                firstname: "required",
                lastname: "required",
                //city: "required",
                state: "required",
                country: "required"
            },
            messages: {
                firstname: "Please enter your firstname",
                lastname: "Please enter your lastname",
                //city: "Please enter a valid email address",
                country: "Please select your country"
            },
            submitHandler: PostData
        });
    });
});

function PostData() {
    $.ajax(url,
           { Id: '1' },
           function (data, textStatus) {
               //alert(textStatus);
           });
}
