javascript - 使用引导验证器验证密码并确认密码字段

Question

我一直坚持通过 Jquery 添加和删除引导验证器类。如果 div 可见，我将添加验证，如果 div 隐藏，则删除。这是我的尝试:

<!--hidden form field-->
<div class="form-group">
    <a href="javascript:validateField();" class="theme-color accountFormToggleBtn display-block">click here to change your password</a>

    <div class="accountFormToggle display-none" id="passwordForm"> 
      <div class="col-md-5">
        <label for="password">Password</label>
        <input type='password' id="password" placeholder="Password" name='pass' class="form-control"  value='' data-bv-excluded="false" required>
      </div>

      <div class="col-md-5 col-md-offset-1">
        <label for="exampleInputEmail1">Confirm password</label>
        <input type='password' id="password2" placeholder="Confirm password" name='password2' class="form-control" value='' data-bv-excluded="false" data-match="#password" required> 
      </div>
    </div> 
</div>

JS代码:

function validateField() {
   
    if($('#passwordForm').is(':visible')) {  
        $("#password").attr('data-bv-excluded',true);   
        $("#password2").attr('data-bv-excluded',true);
    } else {
        $("#password").attr('data-bv-excluded',false);   
        $("#password2").attr('data-bv-excluded',false);
    }
}

如果 div 可见或隐藏，则验证工作。但确认密码与密码字段的数据不匹配。
请帮助我如何根据 div 的可见性匹配密码并确认密码字段？

您可以通过切换 .display-none 来实现此目的。类如下例所示。

function validateField() {
  let cont = $('#passwordForm');
  if (cont.hasClass('display-none')) {
    cont.removeClass('display-none');
    $("#password").attr('data-bv-validatorname', true);
    $("#password2").attr('data-bv-validatorname', true);
  } else {
    cont.addClass('display-none');
    $("#password").attr('data-bv-validatorname', false);
    $("#password2").attr('data-bv-validatorname', false);
  }
  console.log(`$("#password").attr('data-bv-validatorname') is ${$("#password2").attr('data-bv-validatorname')}`);
  console.log(`$("#password2").attr('data-bv-validatorname') is ${$("#password2").attr('data-bv-validatorname')}`);
}

$('#passwordForm').bootstrapValidator({
      message: 'This value is not valid',
      live: 'enabled',
      fields: {
        password: {
          message: 'The password is not valid',
          validators: {
            notEmpty: {
              message: 'The password is required and cannot be empty'
            },
            identical: {
              field: 'password',
              message: 'The passwords must match. '
            },
            stringLength: {
              min: 6,
              max: 30,
              message: 'The password must be more than 6 and less than 30 characters long'
            },
            regexp: {
              regexp: /^[a-zA-Z0-9_]+$/,
              message: 'The password can only consist of alphabetical, number and underscore'
            }
          }
        },
        password2: {
          message: 'The password2 is not valid',
          validators: {
            notEmpty: {
              message: 'The password2 is required and cannot be empty'
            },
            identical: {
              field: 'password',
              message: 'The passwords must match. '
            },
            stringLength: {
              min: 6,
              max: 30,
              message: 'The password2 must be more than 6 and less than 30 characters long'
            },
            regexp: {
              regexp: /^[a-zA-Z0-9_]+$/,
              message: 'The password2 can only consist of alphabetical, number and underscore'
            }
          }
        }
      }
      });


    $('a.accountFormToggleBtn').on('click', function() {
      validateField();
    }); 

.display-none {
  display: none;
}
