javascript - 将代码从 vbscript 转换为 Jscript？

Question

如何将以下 VBScript 代码转换为用于获取所有用户的用户配置文件路径的 JScript？

Set oWshNet = CreateObject("Wscript.Network")
sComputer = oWshNet.ComputerName
'For remote computer
'sComputer = "some name or IP"
Const HKLM = &H80000002

sProfileRegBase = "SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList" 
Set oReg = GetObject("WinMgmts:{impersonationLevel=impersonate}!//" _ 
                & sComputer & "/root/default:StdRegProv")
Set oWMI = GetObject("WinMgmts:{impersonationLevel=impersonate}!//" _ 
                & sComputer & "/root/cimv2")
Set colItems = oWMI.ExecQuery _ 
                ("Select Name,SID from Win32_UserAccount WHERE Domain = '" _ 
                & sComputer & "'",,48)
For Each oItem In colItems
  sAddInfo = ""
  Wscript.Echo "User name: " & oItem.Name & sAddInfo
  oReg.GetExpandedStringValue HKLM, sProfileRegBase& "\" & oItem.SID, _ 
                  "ProfileImagePath", sProfilePath
  If IsNull(sProfilePath) Then
    sProfilePath = "(none defined)"
  End If <br>
  Wscript.Echo "Profile path: " & sProfilePath
  Wscript.Echo   ' blank line
Next

我在转换方面取得了部分成功，但坚持了两件事。

1. 请确认我对 oReg = GetObject("WinMgmts:\\\\.\\root\\default:StdRegProv"); 的用法是否正确且与那个相同这是在代码中给出的。如果不是，请建议正确的用法。

2. JScript 中 GetExpandedStringValue 的等价物是什么？如果没有，在获取值之前验证注册表项是否存在的更好方法是什么？

这是一个示例解决方案:(来自 http://www.windowsitpro.com/content/content/93402/Listing_05.txt)

// GetSystemPath.js

var HKEY_LOCAL_MACHINE = 0x80000002;
var ENVIRONMENT_SUBKEY = "SYSTEM\\CurrentControlSet\\Control"
  + "\\Session Manager\\Environment";

var computer, regprov, method, inparams, outparams, systempath;

// CALLOUT A
// Step 1: Get an instance of the WMI object.
computer = ".";
regprov = GetObject("winmgmts:{impersonationlevel=impersonate}!//"
  + computer + "/root/default:StdRegProv");
// END CALLOUT A

// CALLOUT B
// Step 2: Create an InParameters object for the method.
method = regprov.Methods_.Item("GetExpandedStringValue");
inparams = method.InParameters.SpawnInstance_();
// END CALLOUT B

// CALLOUT C
// Step 3: Set the InParameters object's properties.
inparams.hDefKey = HKEY_LOCAL_MACHINE;
inparams.sSubKeyName = ENVIRONMENT_SUBKEY;
inparams.sValueName = "Path";
// END CALLOUT C

// CALLOUT D
// Step 4: Call ExecMethod_ to return an OutParameters object.
outparams = regprov.ExecMethod_(method.Name, inparams);
// END CALLOUT D

// CALLOUT E
// Step 5: The OutParameters object contains the method's results.
if (outparams.ReturnValue == 0) {
  systempath = outparams.sValue;
  WScript.Echo(systempath);
}
// END CALLOUT E
