MVC3でjquery.validate.jsのエラー表示カスタマイズ

gistfile1.js

var validator = $("#form").data('validator');
validator.settings.errorPlacement = function (error, element) {
  // Error placement for single elements
  var offset = element.offset();
  error.insertBefore(element)
  error.addClass('message');  // add a class to the wrapper
  error.css('position', 'absolute');
  error.css('left', offset.left + element.outerWidth());
  error.css('top', offset.top - (element.height() / 2));
};
