"继续] （对于下一次迭代）在VBScript上 [英] "Continue" (to next iteration) on VBScript

问题描述

一位同事和我试图在VBScriptFor / Next循环中找到一种相当于continue语句的方法。

A colleague and I were trying to figure out a way of doing the equivalent of a "continue" statement within a VBScript "For/Next" loop.

无处不在我们发现我们发现人们没有办法在VBScript中做这个没有讨厌的嵌套，这对我们来说不是一个选择，因为它是一个非常大的循环。

Everywhere we looked we found people had no way to do this in VBScript without having nasty nestings, which is not an option for us since it is a quite big loop.

我们来了出于这个想法。它会像继续（下一次迭代）一样工作吗？有没有人有更好的解决方法或改进建议？

We came out with this idea. Would it work just as a "continue(to next iteration)"? Does anyone have any better workaround or improvement suggestion?

For i=1 to N
  For workaroundloop = 1 to 1
    [Code]
    If Condition1 Then
      Exit For
    End If

    [MoreCode]
    If Condition2 Then
      Exit For
    End If

    [MoreCode]
    If Condition2 Then
      Exit For
    End If

    [...]

  Next
Next

推荐答案

您的建议可行，但使用Do循环可能会更具可读性。

Your suggestion would work, but using a Do loop might be a little more readable.

这实际上是C中的一个成语 - 而不是使用goto，如果你想早点摆脱构造，你可以使用break语句进行do {} while（0）循环。

This is actually an idiom in C - instead of using a goto, you can have a do { } while (0) loop with a break statement if you want to bail out of the construct early.

Dim i

For i = 0 To 10
    Do
        If i = 4 Then Exit Do
        WScript.Echo i
    Loop While False
Next

如同粉碎所示，如果你删除额外的缩进级别，它看起来好一点。

As crush suggests, it looks a little better if you remove the extra indentation level.

Dim i

For i = 0 To 10: Do
    If i = 4 Then Exit Do
    WScript.Echo i
Loop While False: Next
