上面的代码第21行，就是调用了jQuery的valildate方法对form 表单进行验证,那么this.options 是怎么得到的呢？
是在$jQval.unobtrusive.parseElement方法里完成的。
 1 parseElement: function (element, skipAttach) {
 2    
 3              var $element = $(element),
 4                  form = $element.parents("form")[0],
 5                  valInfo, rules, messages;
 6 
 7              if (!form) {  // Cannot do client-side validation without a form
 8                  return;
 9              }
10 
11              valInfo = validationInfo(form);
12              valInfo.options.rules[element.name] = rules = {};
13              valInfo.options.messages[element.name] = messages = {};
