javascript - 将 Bootstrap 验证消息颜色更改为红色

Question

如果输入无效的电子邮件，我有一个表单会发布错误消息。我想将错误消息文本更改为红色。我该怎么做？

$('#subscribe-form').bootstrapValidator({
  live: 'disabled',
  fields: {
    email: {
      validators: {
        emailAddress: {
          message: 'Please enter a valid email address'
        }
      }
    },
  }
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form role="form" id="subscribe-form">
  <div class="form-group">
    <input type="email" class="form-control custom-email" name="email" id="email" placeholder="Email Address">
  </div>
  <button type="submit" class="btn btn-large custom-button">Sign up !</button>
</form>

Answer 1

只需在您的代码中添加以下 css

.has-error .help-block {
  color: red;
}

$('#subscribe-form').bootstrapValidator({
  live: 'disabled',
  fields: {
    email: {
      validators: {
        emailAddress: {
          message: 'Please enter a valid email address'
        }
      }
    },
  }
});

.has-error .help-block {
  color: red;
}
