Asp classic vbscript返回整词字符串<=指定限制
我想在vbScript(经典ASP)中,在不剪切单词的情况下将字符串解析为指定长度。最后一个字符串可能小于指定的长度(以避免剪切单词),但不应超过该长度。假设您在空格中打断单词Asp classic vbscript返回整词字符串<=指定限制,asp-classic,vbscript,Asp Classic,Vbscript,我想在vbScript(经典ASP)中,在不剪切单词的情况下将字符串解析为指定长度。最后一个字符串可能小于指定的长度(以避免剪切单词),但不应超过该长度。假设您在空格中打断单词 startIndex = 0 index = 1 do while len(inputString) - startIndex > desiredLength tmp = mid(inputString, 0, desiredLength) outputStrings[index] = left(t
startIndex = 0
index = 1

outputStrings[index] = left(tmp, instrrev(tmp, " ")-1)
startIndex = startIndex + len(outputStrings[index]) + 1

@Caveatrob:还假设您在空格上断开:
<%
Option Explicit
Function TrimIt(sInput, iLength)
Dim aWords, iCounter, sOutput, sTmp
sOutput = sInput
If InStr(sInput, " ") > 0 Then
aWords = Split(sInput, " ")
For iCounter = 0 To UBound(aWords)
If Len(aWords(iCounter) & " ") + Len(sTmp) <= iLength Then
sTmp = sTmp & " " & aWords(iCounter)
Else
Exit For
End If
Next
sOutput = sTmp
End If
TrimIt = sOutput
End Function
Response.Write TrimIt("This works slightly better", 11)
%>
0那么
aWords=拆分(单字,“”)
对于iCounter=0到UBound(aWords)
如果Len(aWords(iCounter)和“”)+Len(sTmp)
以下两个答案中的任何一个对您有用吗?:-)
