Example 1: submit ajax form validation jquery

    submitHandler: function(form) {
        $.ajax({
            url: form.action,
            type: form.method,
            data: $(form).serialize(),
            success: function(response) {
                $('#answers').html(response);
            }            
        });
    }
});

Example 2: How to call the ajax when form is valid

BY LOVE,
1- $("form").valid() is the main method which is checking the form is valid or not
2- 'btnsave' is the ID of the HTML BUTTON  element.
3- Jquery pluggin should be added in this order
	<script src="~/Scripts/jquery-1.7.1.min.js"></script>
    <script src="~/Scripts/jquery.validate.js"></script>
    <script src="~/Scripts/jquery.validate.unobtrusive.js"></script>

$('#btnSave').click(function () {
        if ($("form").valid()) {
            //alert('FORM VALID');
            $.ajax({
                url: 'http://localhost:3932/api/EmployeeService/Save',
                type: 'POST',
                dataType: 'json',
                success: function () {
                    alert('Employee Save successfully');
                },
                error: function (xhr, textStatus, errorThrown) {
                    alert('Error occured');
                }
            });
        }
    });
