【问题描述】：
我有一个非常广泛的 300 多行用户添加脚本，用 PowerShell 编写，专为非管理员设计，无需管理员权限（它会自我提升）也无需进入 ADUC 即可将用户添加到 Windows 域。
有一个部分（如下）要求提供电话号码、清理输入并正确格式化它们以同步到 Azure/O365。它还会检查以确保办公室和手机的输入是 10 位数字，如果不是，则会引发错误对话框。我想找到一种方法，不仅可以将错误框扔到一边，还可以让脚本返回到电话输入代码的顶部，让他们在点击“确定”按钮后重新输入数字。这就是我不知所措的地方 - 让它回到该部分的顶部。
提前致谢！ =)

designed for non-admins to add users to the Windows domain...为什么.... -
您正在寻找的称为事件处理程序
-
因为不是每个人都需要成为域管理员才能完成这项繁重的工作。而且因为脚本在后端做了很多工作来正确格式化属性以进行同步，并进行了一堆更新，而帮助台人员不必手动执行这些更新，并且有一个疯狂的分步过程。目前为止很方便，但我只需要这一段反复询问，直到输入正确的位数。
-
您可以尝试将提示部分包裹在
Do { .. } Until ($outputexpected) -
可以授予 AD 权限以允许创建/修改帐户，而无需授予完整的域管理员权限。如果他们拥有这些权限，您就不需要让它自我提升（这也引出了一个问题，即您如何保护凭据，以便某人不能出于其他原因自行提升）
