如何使用 Bootstrap 验证器在 Bootstrap v4 上进行验证？

Question

我刚从 v3 迁移到 Bootstrap v4。 Bootstrap 验证器正在部分工作。 JavaScript 部分仍然有效。但是，样式消失了。

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

外观如下：

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 class 。出现错误时如何修复标签高亮和输入框高亮？

我已经根据 BS4 转换了所有 classes。这是我的代码：

$('#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);

.help-block {
    color: red;
}

Answer 1

首先你的脚本文件顺序不对......jQuery应该在最上面......你已经使用了bootstrap-validator两次..不需要......

你的问题的答案是你必须使用 has-danger class 来设置 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);
}

堆栈片段

$('#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);
}
