Question

我正在尝试创建一个交互式PowerShell脚本，该脚本将执行以下操作：

菜单1-提示用户输入文件路径。然后基于文件路径，我将进入目录

菜单2-用户输入完成后，我将拥有第二个菜单，提示用户选择要解析的文件

一个用户选择选项，它将输出文件，然后从菜单2重新启动

我不了解如何仅显示第一个菜单，然后在提交用户输入后跳到第二个菜单，并且一旦用户选择并解析了文件-返回第二个菜单，直到“ Q”。

$Filepath = Read-Host -Prompt 'Please Enter File Path'
do
cd $FilePath

function Show-Menu {
    Clear-Host

    Write-Host "1: Press '1' for parsing test.txt"
    Write-Host "2: Press '2' for parsing test2.txt"
    Write-Host "3: Press '3' for parsing test3.txt"
    Write-Host "Q: Press 'Q' to quit."
}

do {
    Show-Menu $selection = Read-Host "Please make a selection"
    switch ($selection) {
        '1' {
            'You chose option #1'
            Clear-Host
            Import-Csv txt.file -Delimiter '|' -Header '1' ,'2' | Out-GridView
        }
    }
    pause
} until ($selection -eq 'q')

Answer 1

您的帖子中没有两个菜单。你只有一个。除非您说您正在考虑“读取主机”菜单。

这是您要完成的事情吗？

Clear-Host

$Filepath = Read-Host -Prompt "`nPlease Enter File Path"
Push-Location -Path $Filepath


$MenuOptions = @'
"Press '1' for parsing test1.txt"
"Press '2' for parsing test2.txt"
"Press '3' for parsing test3.txt"
"Press 'Q' to quit."
'@

"`n$MenuOptions"

while(($selection  = Read-Host -Prompt "`nSelect a option") -ne 'Q')
{
    Clear-Host

    "`n$MenuOptions"

    switch( $selection )
    {
        1 { 'Code for doing option 1 stuff' }
        2 { 'Code for doing option 2 stuff' }
        3 { 'Code for doing option 3 stuff' }
        Q { 'Quit' }
        default {'Invalid entry'}
    }

    Pop-Location
}

Answer 2

不使用循环，另一种选择是调用“菜单”函数本身以在完成解析后再次显示菜单。

您还可以使用Host.ChoiceDescription来构建并显示菜单。

$Filepath = Read-Host -Prompt 'Please Enter File Path'
Set-Location $FilePath

function Get-Selection {
    $Title = "Please make a selection"
    $Message = "Select File for parsing"
    $Option1 = New-Object System.Management.Automation.Host.ChoiceDescription "test.txt"
    $Option2 = New-Object System.Management.Automation.Host.ChoiceDescription "test2.txt"
    $Option3 = New-Object System.Management.Automation.Host.ChoiceDescription "test3.txt"
    $Option4 = New-Object System.Management.Automation.Host.ChoiceDescription "Quit"
    $Options = [System.Management.Automation.Host.ChoiceDescription[]]($Option1,$Option2,$Option3,$Option4)

    $host.ui.PromptForChoice($title, $message, $options, 0)
}

function Show-Menu {
    switch (Get-Selection) {
        0 {
            Write-Host 'You chose option #1'
            Clear-Host
            Import-Csv txt.file -Delimiter '|' -Header '1' ,'2' | Out-GridView
            Show-Menu # Show menu for next choice
        }
        1 {
            Write-Host 'You chose option #2'
            Clear-Host
            # Import-Csv
            Show-Menu # Show menu for next choice
        }
        2 {
            Write-Host 'You chose option #2'
            Clear-Host
            # Import-Csv
            Show-Menu # Show menu for next choice
        }
        3 {
            Write-Host 'Quit'
        }
    }
}

Show-Menu # Load menu when script is run

PowerShell用户输入，菜单，子菜单，
