如何使用Bootstrap验证器对Bootstrap v4进行验证？

Question

我刚刚从v3迁移到Bootstrap v4。并且Bootstrap Validator部分正常工作。 JavaScript部分仍然有效。然而，造型已经消失。

这是我使用的bootstrap验证器：https://github.com/1000hz/bootstrap-validator

以下是它的外观：

看起来像这样：

我手动添加了css。因此错误消息有效。

Bootstrap验证器已经添加了.has-danger类。 如何在发生错误时修复标签突出显示和输入框高亮显示？

我已根据BS4转换了所有课程。这是我的代码：

＆＃13;

＆＃13;

$('#inputFirstName').attr('data-required-error', uiData.Error_FieldRequired_FirstName);
$('#inputLastName').attr('data-required-error', uiData.Error_FieldRequired_LastName);
$('#inputPhone').attr('data-required-error', uiData.Error_FieldRequired_Phone);
$('#inputEmail').attr('data-required-error', uiData.Error_FieldRequired_Email);
$('#inputTitle').attr('data-required-error', uiData.Error_FieldRequired_Title);

$('#inputPhone').attr('data-pattern-error', uiData.Error_InvalidPhone);
$('#inputEmail').attr('data-pattern-error', uiData.Error_InvalidEmail);
$('#inputEmail').attr('data-match-error', uiData.Error_InvalidEmail);

＆＃13;

.help-block {
    color: red;
}

Answer 1

首先，您的脚本文件不合规...... jQuery应该在最顶层......并且您已经使用了bootstrap-validator两次......不需要......

回答你的问题是你必须使用has-danger课来设定label

的样式

.form-group.has-error.has-danger .form-control-label {
  color: red;
}
.form-group.has-error.has-danger .form-control{
  border: 1px solid red;
  box-shadow: 0 0 0 0.2rem rgba(250, 16, 0, 0.18);
}

Stack Snippet

$('#userForm').validator();

.help-block {
  color: red;
}

.form-group.has-error.has-danger .form-control-label {
  color: red;
}

.form-group.has-error.has-danger .form-control {
  border: 1px solid red;
  box-shadow: 0 0 0 0.2rem rgba(250, 16, 0, 0.18);
}
