jquery的validation表单验证插件，当填写不符合规则时，添加bootstrap的has-error问题

Question

用jquery的validation表单验证插件，当填写不符合规则时，给bootstrap中每个input的父元素加上has-error的class，就会让该元素变成红色，可是bootstrap中不同类型的表单，父元素层级不同，validation根据input、textarea、radio...等本身的name来查找的元素，现在要给不同层级的父元素设置has-error属性，该怎么办？
1、bootstrap不同类型的表单

<form>
  <fieldset class="form-group">
    <label for="exampleInputEmail1">Email address</label>
    <input type="email" class="form-control" id="exampleInputEmail1" placeholder="Enter email">
    <small class="text-muted">We'll never share your email with anyone else.</small>
  </fieldset>
  <fieldset class="form-group">
    <label for="exampleInputPassword1">Password</label>
    <input type="password" class="form-control" id="exampleInputPassword1" placeholder="Password">
  </fieldset>
  <fieldset class="form-group">
    <label for="exampleSelect1">Example select</label>
    <select class="form-control" id="exampleSelect1">
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
      <option>5</option>
    </select>
  </fieldset>
  <fieldset class="form-group">
    <label for="exampleSelect2">Example multiple select</label>
    <select multiple class="form-control" id="exampleSelect2">
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
      <option>5</option>
    </select>
  </fieldset>
  <fieldset class="form-group">
    <label for="exampleTextarea">Example textarea</label>
    <textarea class="form-control" id="exampleTextarea" rows="3"></textarea>
  </fieldset>
  <fieldset class="form-group">
    <label for="exampleInputFile">File input</label>
    <input type="file" class="form-control-file" id="exampleInputFile">
    <small class="text-muted">This is some placeholder block-level help text for the above input. It's a bit lighter and easily wraps to a new line.</small>
  </fieldset>
  <div class="radio">
    <label>
      <input type="radio" name="optionsRadios" id="optionsRadios1" value="option1" checked>
      Option one is this and that&mdash;be sure to include why it's great
    </label>
  </div>
  <div class="radio">
    <label>
      <input type="radio" name="optionsRadios" id="optionsRadios2" value="option2">
      Option two can be something else and selecting it will deselect option one
    </label>
  </div>
  <div class="radio disabled">
    <label>
      <input type="radio" name="optionsRadios" id="optionsRadios3" value="option3" disabled>
      Option three is disabled
    </label>
  </div>
  <div class="checkbox">
    <label>
      <input type="checkbox"> Check me out
    </label>
  </div>
  <button type="submit" class="btn btn-primary">Submit</button>
</form>

2、bootstrap验证样式

<div class="form-group has-success">
  <label class="control-label" for="inputSuccess1">Input with success</label>
  <input type="text" class="form-control form-control-success" id="inputSuccess1">
</div>
<div class="form-group has-warning">
  <label class="control-label" for="inputWarning1">Input with warning</label>
  <input type="text" class="form-control form-control-warning" id="inputWarning1">
</div>
<div class="form-group has-error">
  <label class="control-label" for="inputError1">Input with error</label>
  <input type="text" class="form-control form-control-error" id="inputError1">
</div>

<div class="has-success">
  <div class="checkbox">
    <label>
      <input type="checkbox" id="checkboxSuccess" value="option1">
      Checkbox with success
    </label>
  </div>
</div>
<div class="has-warning">
  <div class="checkbox">
    <label>
      <input type="checkbox" id="checkboxWarning" value="option1">
      Checkbox with warning
    </label>
  </div>
</div>
<div class="has-error">
  <div class="checkbox">
    <label>
      <input type="checkbox" id="checkboxError" value="option1">
      Checkbox with error
    </label>
  </div>
</div>
