});

  rules: {

    field: {

      required: true,

      max: #field1 //from field1 dynamic value???

    //max: 23 //static value

    }

  }

});

<script src=http://code.jquery.com/jquery-1.11.1.min.js></script>

<script src=http://jqueryvalidation.org/files/dist/jquery.validate.min.js></script>

<script src=http://jqueryvalidation.org/files/dist/additional-methods.min.js></script>

Return the value of the field using a function.

$( #myform ).validate({

    rules: {

        field: {

            required: true,

            max: function() {

                return parseInt($('#field1').val());

            }

        }

    }

});

Remember to enclose the value within parseInt or the number could be evaluated as a string.
