Powershell无法扩展此javascript内容 [英] Powershell cannot expand this javascript content

问题描述

将答案应用于我之前的问题如何使用powershell扩展文件内容

Applying the answer to my previous question How to expand file content with powershell

我试图扩大这个时偶然发现致命错误：

I stumbled upon a fatal error when trying to expand this :

test.js：

<script type="text/javascript">
    $('.mylink').click(function(event) {
        var hash = $(this).attr("href");
    });
    // $var
</script>  

test.ps1

$test = get-content -raw test.html
$var = "test"

# Write to output file using UTF-8 encoding *without a BOM*.
[IO.File]::WriteAllText(
  "$PWD/out.html",
  $ExecutionContext.InvokeCommand.ExpandString($test)
)

推荐答案

$ 是一个PowerShell中的特殊符号和 $（）表示扩展了内容的内联表达式，因此您需要在扩展之前通过添加反引号来转义它。 之前 $（：

$ is a special symbol in PowerShell and $() denotes an inlined expression expanded with its contents so you'll need to escape it before expansion by adding a backtick ` before $(:

$ExecutionContext.InvokeCommand.ExpandString(($test -replace '\$\(', '`$('))

但是，如果你在模板中使用PowerShell的 $（），那么这个问题需要更智能的替换，可能需要更复杂的算法来区分jQuery和PS。

However, if you use PowerShell's $() in the template then it's a problem that would require a smarter replacement and probably much more complex algorithm to differentiate between jQuery and PS.
