下面是我的 html 代码的摘录，在我的 Powershell 脚本中定义为 $html:

当我将其作为 html 文件运行时，它运行完全正常并且脚本按预期运行。但是，如果我通过 PS 解析它会出现错误:
document : The term 'document' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. At line:46 char:6 + $( document ).ready(function() { // 6,32 5,38 2,34 + ~~~~~~~~ + CategoryInfo : ObjectNotFound: (document:String) [], CommandNot FoundException + FullyQualifiedErrorId : CommandNotFoundException
我尝试将“$( document )”更改为“$(”document”)，添加引号，这似乎有效，但是当您查看输出的 html 文件时，它会删除“$(”和")"，因此它有效地禁用了由于语法不正确而启用的脚本。
是因为它将美元符号视为 PS 变量吗？我该如何解决这个问题？
谢谢
最佳答案
如您所知，问题行有这个
$( document )
这是 PowerShell 的语法 subexpressions $() . PowerShell 告诉您“文档”不是命令。在 PowerShell 中使用反引号转义“$”，这样它就不会被特殊对待
`$( document )
您对以下行有类似的问题，但可能不那么明显
$("#test-circle").circliful({
处理后在您的此处字符串中看起来像这样
#test-circle.circliful({
您还需要转义那个美元符号。
您可以只使用带单引号的 herestring (@' '@)，这样就可以避免这个问题。但是，由于您是变量替换，因此您不能在没有更多更改的情况下走这条路。
关于javascript - 为什么我从 here-string 中收到 "not a cmdlet"错误？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/40809697/
