如何在主脚本中运行一段代码，然后用上述代码的结果更新主脚本

Question

下面的代码是大主脚本的一部分，因为日期是随机的，所以我不能预先编写显示格式，所以我正在生成显示代码。所以使用下面的代码来格式化显示。

$dates = ("2022-07-29","2022-07-28","2022-07-27")
    function display ($dates){
                $num = 1
                $beg = '"{0,-25}'
                $end = '" -f "Job_Name"'
                    ForEach ($dt in $dates){
                
                $ft += " {$num,10}"
                
                $dtt += ",""$dt"""
                $num ++
                                                }
                "$($beg) $($ft) $($end)$($dtt)"
                                    }
                
               display $dates

当主脚本运行时，我将获得如下所示的输出，我希望在主脚本中运行代码并使用输出更新脚本。"{0，-25} {1,10} {2,10} {3,10}“-f "Job_Name”、"2022-07-29“、"2022-07-28”、"2022-07-27“在主脚本运行时显示为

Job_name 2022-07-29 2022-07-28 2022-07-27

实际上，下面是我的主要代码，在这里，我在代码中手动编写日期以获得输出。但是我想要这件自动的，知道我能做什么吗？

[CmdletBinding()]
param (
    [Parameter(Mandatory = $True)][string]$vip,
    [Parameter(Mandatory = $True)][string]$username,
    [Parameter()][string]$domain = 'local',
    [Parameter(Mandatory = $True)][array]$jobNames, # job to run
    [Parameter()][int]$Days
)

                    if ($jobname -notin $data.keys){
                             $data[$jobname]=@{}

                            foreach ($run in $runs){

                                                 }

如果您先将日期放在预期的输出上，然后将$days的值从14更改为任何其他值，则必须再次用日期更新上述代码，以获得所需的输出。我想要显示得到调整值的$days变化。

相对于您发布的内容，结果并不是您所显示的结果。

(除非您正在脚本的其他地方进行格式化，而您没有显示)

Clear-Host
$dates = ("2022-07-29","2022-07-28","2022-07-27")

function display ($dates)
{
    $num = 1
    $beg = '"{0,-25}'
    $end = '" -f "Job_Name"'

    ForEach ($dt in $dates)
    {         
        $ft  += " {$num,10}"     
        $dtt += ",""$dt"""
        $num ++
    }

    "$($beg) $($ft) $($end)$($dtt)"
}
    
display $dates
# Results
<#
"{0,-25}  {1,10} {2,10} {3,10} " -f "Job_Name","2022-07-29","2022-07-28","2022-07-27"  
#>  

您正在传递一个数组，因此响应应该作为数组处理。

Clear-Host
$dates | 
ForEach-Object {$PSItem}
2022-07-29
2022-07-28
2022-07-27

Clear-Host
$dates | 
ForEach{display -dates $PSitem}
# Results
<#
"{0,-25}  {1,10} " -f "Job_Name","2022-07-29"
"{0,-25}  {1,10} " -f "Job_Name","2022-07-28"
"{0,-25}  {1,10} " -f "Job_Name","2022-07-27"
#>

然后根据需要处理这些输出行。

，和“@iRon”一样。。

现在，您的帖子只发送到控制台，如果您需要使用脚本中的其他地方的数据，那么您需要捕获它并以这种方式使用它。

您可以使用PowerShell变量压缩将输出到屏幕并捕获一个变量，以便根据需要使用。

Clear-Host
($DisplayRecords = $dates | 
ForEach{display -dates $PSitem})
# Results
<#
"{0,-25}  {1,10} " -f "Job_Name","2022-07-29"
"{0,-25}  {1,10} " -f "Job_Name","2022-07-28"
"{0,-25}  {1,10} " -f "Job_Name","2022-07-27"
#>

Clear-Host
$DisplayRecords
# Results
<#
"{0,-25}  {1,10} " -f "Job_Name","2022-07-29"
"{0,-25}  {1,10} " -f "Job_Name","2022-07-28"
"{0,-25}  {1,10} " -f "Job_Name","2022-07-27"
#>

然后你可以随心所欲地挑选：

Clear-Host
$DisplayRecords[0]
# Results
<#
"{0,-25}  {1,10} " -f "Job_Name","2022-07-29"
#>

Clear-Host
$DisplayRecords[1]
# Results
<#
"{0,-25}  {1,10} " -f "Job_Name","2022-07-28"
#>

Clear-Host
$DisplayRecords[2]
# Results
<#
"{0,-25}  {1,10} " -f "Job_Name","2022-07-27"
#>

更新-跟进我的评论如下：

Clear-Host
$dates = ("2022-07-29","2022-07-28","2022-07-27")

function display ($dates)
{

    $end = 'Job_Name '

    ForEach ($dt in $dates)
    { $dtt += $dt }

    $end + $dtt
}
    
display $dates
# Results
<#
Job_Name 2022-07-292022-07-282022-07-27 
#>
