Question

我有下面的代码片段，应该给用户（我自己）一个YesNo框。如果我选择是，则为变量赋值（$ Category）。如果我选择No，它应该启动IncOrRitm功能，然后我从两个单选按钮中选择。每个按钮都有一个分配给它的变量，其值为该变量的值。如果选择否，则分配给我选择的任何单选按钮的变量的值应分配给$ Category变量。

逻辑是：

正确的类别？

是 - ＆gt; $ Category =是
否 - ＆gt;票应该是什么？
- 事件 - ＆gt; $ Category = Incident
- RITM - ＆gt; $ Category = RITM

但是，只有此代码的“是”部分有效。我不确定我是否遗漏了某些东西，或者该函数是否嵌套错误，或者是什么......

# is the ticket correctly listed as an incident/ritm

$ButtonType = [System.Windows.MessageBoxButton]::YesNo
$MessageTitle = "Incident or RITM"
$MessageBody = "Was the category correctly selected?"
$IncOrRITM = [System.Windows.MessageBox]::Show($MessageBody,$MessageTitle,$ButtonType)

    {
        $Category = "Correct"
    }

    IncOrRITM

Answer 1

在IncOrRITM函数中，$Catalog在分配给它后成为局部变量。你不会返回它的值，所以它会丢失。

You can see a detailed explanation of variable scope in this answer on another question

您应该从函数返回所需的值，然后将$Category分配给其调用：

function IncOrRITM {
    # Other code

    if ($DialogResult -eq "OK")
            {
                if ($RadioButton1.Checked){ $RB1 }
                if ($RadioButton2.Checked){ $RB2 }
            }
        elseif ($DialogResult -eq "Cancel")
            {
                break
            }
}

$Category = IncOrRITM

Answer 2

将$ global：添加到变量中会修复它。

Powershell - IfElse中的功能不提供结果
