我可以使用VBScript初始化用JScript编写的对象吗？

Question

我正在尝试编写WSH登录脚本。整个公司的管理员需要能够自定义脚本的执行，并为特定位置和用户执行其他脚本。为了使他们的工作更轻松，我想提供一个管理员可以在其脚本中访问的API。如果我使用JScript编写我的API，是否可以初始化通过VBScript定义的对象？例如，请考虑以下代码：

<!-- The WSF logon script file --> 
<package> 
    <job> 
     <script language="JScript"> 
      // A demonstration function 
      function OverNineThousand() { 
       return 9001; 
      } 

      // A demonstration "class" 
      function WorkstationClass() { 
       var os = "Windows XP"; 

       this.getOperatingSystem = function() { 
        return os; 
       } 
      } 
     </script> 

     <script language="VBScript"> 
      Dim bigNumber, workstation 

      '// This assignment works properly. 
      bigNumber = OverNineThousand() 

      '// This assignment causes an error. Am I doing it wrong? 
      Set workstation = New WorkstationClass() 

      '// Execution never gets this far 
      WScript.Echo workstation.getOperatingSystem() 
     </script> 
    </job> 
</package> 

有没有什么办法可以完成我想要做的事情？

VBScript和JScript似乎不同意如何初始化一个对象。但是，一旦对象被初始化，它就会被两种语言所识别。为了解决这个问题，我必须在JScript中创建对象，然后将其返回给VBScript调用者，如下所示。

<package> 
    <job> 
     <script language="JScript"> 
      // A demonstration "class" 
      function WorkstationClass() { 
       var os = "Windows XP"; 

       this.getOperatingSystem = function() { 
        return os; 
       } 
      } 

      function CreateWorkstation() { 
       return new WorkstationClass(); 
      } 
     </script> 

     <script language="VBScript"> 
      Dim workstation 

      '// This assignment causes an error. 
      '// Set workstation = New WorkstationClass() 

      '// This works! 
      Set workstation = CreateWorkstation() 

      '// Prints "Windows XP" 
      WScript.Echo workstation.getOperatingSystem() 
     </script> 
    </job> 
</package>
