datetimepicker的jquery验证 - 结束日期必须大于开始日期

Question

我目前有一个注册表格，需要2个教育日期，开始日期和结束日期。我的验证适用于除这些日期之外的所有输入字段。我需要他们检查开始日期是否在结束日期之前。

我目前正在http://xdsoft.net/jqplugins/datetimepicker/

的库中使用datetimepicker

我已经在网上看过使用通常的jquery库的例子，但不是这个特别的例子，我对如何进行验证感到有些困惑。

INITIALISES DATETIMEPICKER

jQuery('#datetimepicker_start_time').datetimepicker({
  startDate:'+1971/05/01'//or 1986/12/08
});

JQUERY VALIDATION

<script>

  $(function() {

    $("#book-form").validate({

        // Specify the validation rules
        rules: {
            firstname: "required",
            lastname: "required",
            start_education_date: "required",
            end_education_date: "required",
            email: {
                required: true,
                email: true
            },
            password: {
                required: true,
                minlength: 5
            },
            agree: "required"
        },

        // Specify the validation error messages
        messages: {
            firstname: "Please enter your first name",
            lastname: "Please enter your last name",
            password: {
                required: "Please provide a password",
                minlength: "Your password must be at least 5 characters long"
            },
            email: "Please enter a valid email address",
            agree: "Please accept our policy"
        },

        submitHandler: function(form) {
            form.submit();
        }
     });

  });

  </script>
