在Javascript文件中定义并调用Wscript函数以在Windows Script Host中运行

Question

我的需要与我提出的问题标题完全相同。

我有一个javascript文件，用于计算每年的感恩节日期，前提是输入年份值。

现在我希望这个javascript可以由 Windows脚本宿主执行，并且还允许在不更改文件类型或扩展名的情况下创建尽可能多的InputBox。

我尝试了以下代码，但它给了我错误expected ;：

ws = WScript.CreateObject('WScript.Shell');
var myDate = new Date();
myDate.setHours(0, 0, 0, 0);

// Function WSHInputBox(Message, Title, Value)
//  ' Provides an InputBox function for JScript
//  ' Can be called from JScript as:
//  ' var result = WSHInputBox("Enter a name", "Input", test);
//  WSHInputBox = InputBox(Message, Title, Value)
// End Function

strYear = GetUserInput( "Enter some input:" )
ws.Popup('Year ?'+strYear);

//var strYear = WSHInputBox("Enter the year", "Thanksgiving Year")
myDate.setYear(parseInt(strYear));

// Determine November 1.
myDate.setDate(1);
myDate.setMonth(10);

// Find Thursday.
var thursday = 4;
while(myDate.getDay() != thursday) {
    myDate.setDate(myDate.getDate() + 1);
}

// Add 3 weeks.
myDate.setDate(myDate.getDate() + 21);

ws.Popup('Result: ' + myDate);

Function UserInput( myPrompt )
' This function prompts the user for some input.
' When the script runs in CSCRIPT.EXE, StdIn is used,
' otherwise the VBScript InputBox( ) function is used.
' myPrompt is the the text used to prompt the user for input.
' The function returns the input typed either on StdIn or in InputBox( ).

    ' Check if the script runs in CSCRIPT.EXE
    If UCase( Right( WScript.FullName, 12 ) ) = "\CSCRIPT.EXE" Then
        ' If so, use StdIn and StdOut
        WScript.StdOut.Write myPrompt & " "
        UserInput = WScript.StdIn.ReadLine
    Else
        ' If not, use InputBox( )
        UserInput = InputBox( myPrompt )
    End If
End Function

Function GetUserInput( myPrompt )
' This function uses Internet Explorer to
' create a dialog and prompt for user input.

    objIE.ToolBar        = False
    objIE.Resizable      = False

                                  & "OnClick=""VBScript:OK.value=1""></p></div>"
    ' Hide the scrollbars
    objIE.Document.body.style.overflow = "auto"
    ' Make the window visible
    objIE.Visible = True
    ' Set focus on input field
    objIE.Document.all.UserInput.focus

    ' Wait till the OK button has been clicked
    On Error Resume Next
    Do While objIE.Document.all.OK.value = 0
        WScript.Sleep 200
        ' Error handling code by Denis St-Pierre
        If Err Then ' user clicked red X (or alt-F4) to close IE window
            IELogin = Array( "", "" )
            objIE.Quit
            Set objIE = Nothing
            Exit Function
        End if
    Loop
    On Error Goto 0


    ' Read the user input from the dialog window
    GetUserInput = objIE.Document.all.UserInput.value

    ' Close and release the object
    objIE.Quit
    Set objIE = Nothing
End Function

WScript.Quit();

有人可以提供帮助，因为我被困在如何在这个相同的Javascript文件中包含这两种类型的代码，我知道有一些方法，但是那是什么？

问题

• 开发人员VickyDev希望在MSFT JScript文件中运行MSFT VBScript函数
• InputBox是VBScript函数，而不是JScript函数

       // Function WSHInputBox(Message, Title, Value)
       //  ' Provides an InputBox function for JScript
       //  ' Can be called from JScript as:
       //  ' var result = WSHInputBox("Enter a name", "Input", test);
       //  WSHInputBox = InputBox(Message, Title, Value)
       // End Function

解决方案

• 使用Windows脚本宿主文件和脚本标签上的语言声明来组合VBScript和JScript。
• 确保在声明JScript之前先声明所有VBScript函数
