我正试图弄清楚如何使用.vbs只使用一个条件来发生多个事件。 (这里我尝试使用case语句。)是否有这样的命令,或者我是否必须为每一行重写命令? (这可以通过在之前的代码行中激活它来在记事本上输入。)
msgbox("I was woundering how old you are.")
age=inputbox("Type age here.",,"")
Select Case age
Case age>24
x=age-24
WshShell.SendKeys "I see you are "&x&" years older than me."
WshShell.SendKeys "{ENTER}"
Case age<24
x=24-age
WshShell.SendKeys "I see you are "&x&" years younger than me."
WshShell.SendKeys "{ENTER}"
Case age=24
WshShell.SendKeys "Wow were the same age!"
WshShell.SendKeys "{ENTER} "
End Select

我认为您正在寻找Select Case True
,Select Case
开关的增强使用:
age = inputbox("I was wondering how old you are.")
Select Case True
' first handle incorrect input
Case (not IsNumeric(age))
WshShell.SendKeys "You silly, you have to enter a number.{ENTER}"
' You can combine cases with a comma:
Case (age<3), (age>120)
WshShell.SendKeys "No, no. I don't think that is correct.{ENTER}"
' Now evaluate correct cases
Case (age>24)
WshShell.SendKeys "I see you are " & age - 24 & " years older than me.{ENTER}"
Case (age<24)
WshShell.SendKeys "I see you are " & 24 - age &" years younger than me.{ENTER}"
Case (age=24)
WshShell.SendKeys "Wow were the same age!{ENTER}"
' Alternatively you can use the Case Else to capture all rest cases
Case Else
' But as all other cases handling the input this should never be reached for this snippet
WshShell.SendKeys "Woah, how do you get here? The Universe Collapse Sequence is now initiated.{ENTER}"
End Select
我添加了一些额外的案例来向您展示这款增强型交换机的强大功能。与If a And b Then
语句相反,逗号的情况是短路的。

将冗余代码封装在过程或函数中。另外,不同的控制结构可能更适合您正在应用的检查类型:
If age>24 Then
TypeResponse "I see you are " & (age-24) & " years older than me."
ElseIf age<24 Then
TypeResponse "I see you are " & (24-age) & " years younger than me."
ElseIf age=24 Then
TypeResponse "Wow were the same age!"
End If
Sub TypeResponse(text)
WshShell.SendKeys text & "{ENTER}"
End Sub
