jQuery的验证动态更新的规则不工作

Question

的jQuery：1.9.1 jQuery的验证：1.11.1

我呈现给用户的用户个人资料页面。当用户更改特殊字段（密码或新密码）时，我想要使某些输入字段为REQUIRED和VALIDATED。但是，这些规则只有一半是可行的，并且表格可以发布。 如果我强制规则（如'全名'和'显示名'），那么他们总是工作。 我可以不动态更新验证规则吗？ 我在做什么错？

<script type="text/javascript"> 
$(document).ready(
    function() 
    { 
     function updateRules() 
     { 
      var mLen = $('#passwordnew').val().length; 
      if (mLen > 0) 
      { 
       $('#passwordold').rules('add', {required: true, minlength: 6}); 
       $('#passwordold').attr('required', 'true'); 
       $('#passwordnew').rules('add', {required: true, notEqual: '#passwordold'}); 
       $('#passwordnew').attr('required', 'true'); 
       $('#passwordconf').rules('add', {required: true, equalTo: '#passwordnew'}); 
       $('#passwordconf').attr('required', 'true'); 
      } else { 
       $('#passwordold').rules('remove'); 
       $('#passwordold').attr('required', 'false'); 
       $('#passwordnew').rules('remove'); 
       $('#passwordnew').attr('required', 'false'); 
       $('#passwordconf').rules('remove'); 
       $('#passwordconf').attr('required', 'false'); 
      } 
     } 

     // Change 
     $('#passwordold').change(updateRules);

.validate()是插件，这种情况应该只是得到所谓一次在DOM准备好初始化。

$(document).ready(function() { 

     // Validation INITIALIZATION 
     $('#profile').validate({ 
      // your options and rules 
     }); 

     function updateRules() { 
      // your code 
     } 

     // Change 
     $('#passwordold').change(updateRules); 
     $('#passwordnew').change(updateRules); 

     // Popover 
     $('#profile :input').hover(
      function() { 
       $(this).popover('show') 
      }, 
      function() { 
       $(this).popover('hide') 
      } 
     ); 

});
