PowerShell：根據值或 IF 語句更改 HTML 表中的單元格顏色

Question

晚上的人。 我有一個 function 我一直在編寫一個腳本，該腳本創建了一個嵌套的軟件信息哈希表並創建了一個 HTML 表。 我已經讓表格工作了，我喜歡它的樣子，但我想要一個單元格（或者可能只是某些單元格中的文本 colors）根據某些值是否匹配來改變顏色。

我的想法是狀態列和背景顏色更改，或者已安裝版本和預期版本列中的文本更改顏色。我不知道我如何編譯表格是否有可能，但不是如果它不起作用，那就是世界末日的事情，更像是“如果可以的話，那就酷”之類的事情。

我的總體問題是：如何根據兩個特定值是否匹配來更改“狀態”列中單元格的背景顏色。 或者，在“安裝程序版本”和“預期版本”列的單元格中更改文本顏色。 下面是我的 function

注意：我對 HTML/CSS 語言非常陌生。 這是我通過大量的谷歌搜索和閱讀所獲得的。

如果沒有事先定義所有變量，就無法重現您的代碼，因此我將使用下面的示例 object 來演示如何做到這一點。

$adminTools = @(
    [ordered]@{
        "Application"       = "PowerShell 7"
        "Installed Version" = [version] '5.1'
        "Expected Version"  = [version] '7.2.6'
    }
    [ordered]@{
        "Application"       = "PuTTY"
        "Installed Version" = [version] '0.77'
        "Expected Version"  = [version] '0.77'
    }
)

我已將這 2 個類添加到您當前的 CSS 中：

.bad {
  background-color: #ffc7ce;
  color: #9c0006;
  font-weight: bold;
}

.good {
  background-color: #c6efce;
  color: #006100;
  font-weight: bold;
}

第一部分是根據條件添加狀態列，如果Installed Version低於Expected Version ：

$export = foreach($item in $adminTools) {
    $item['Status'] = 'Up to Date'
    if($item['Installed Version'] -lt $item['Expected Version']) {
        $item['Status'] = 'Needs Update'
    }
    [pscustomobject] $item
}

現在我們可以使用Regex.Replace(String, String, MatchEvaluator)結合哈希表，我們可以使用該哈希表將<td>標記的<td>標記替換為取決於捕獲組中匹配值的類：

$map = @{
    'Up to Date'   = '<td class="good">'
    'Needs Update' = '<td class="bad">'
}

$html = $export | ConvertTo-Html -PreContent $style -Head '<h1>Hello world</h1>'
[regex]::Replace($html, '(?i)<td>(Needs Update|Up to Date)', {
    param($s)
    $map[$s.Groups[1].Value] + $s.Groups[1].Value
}) | Set-Content test.html

Invoke-Item test.html
