Vbscript：将文本字符串分成小块并将其放入数组中

Question

我需要将一个长文本字符串分成大约每 500 个字符（不是特殊字符）一次的小片段，形成一个包含所有句子的数组，然后将它们放在一起，用特定字符（例如 / /）分隔。如下：

“这个文本是一个非常非常大的文本。”

所以，我明白了：

arrTxt(0) = "This is"
arrTxt(1) = "a very"
arrTxt(2) = "very large text"
...

最后：

response.write arrTxt(0) & "//" & arrTxt(1) & "//" & arrTxt(2)...

由于我对经典 asp 的了解有限，我最接近预期的结果如下：

length = 200
strText = "This text is a very very large."
lines = ((Len (input) / length) - 1)
For i = 0 To (Len (lines) - 1)
txt = Left (input, (i * length)) & "/ /"
response.write txt
Next

但是，这会返回一个重复且重叠的文本字符串：“这是//这是一个//这是一个文本//...

对 vbscript 有任何想法吗？谢谢！

不使用数组，你可以随时构建字符串

Const LIMIT = 500
Const DELIMITER = "//"
' your input string - String() creates a new string by repeating the second parameter by the given
' number of times
dim INSTRING: INSTRING = String(500, "a") & String(500, "b") & String(500, "c")


dim current: current = Empty
dim rmainder: rmainder = INSTRING 
dim output: output = Empty
' loop while there's still a remaining string
do while len(rmainder) <> 0
    ' get the next 500 characters
    current = left(rmainder, LIMIT)
    ' remove this 500 characters from the remainder, creating a new remainder
    rmainder = right(rmainder, len(rmainder) - len(current))
    ' build the output string
    output  = output  & current & DELIMITER
loop
' remove the lastmost delimiter
output = left(output, len(output) - len(DELIMITER))
' output to page
Response.Write output

如果真的需要数组，那么可以split(output, DELIMITER)

这是一个尝试：

Dim strText as String
Dim strTemp as String
Dim arrText()
Dim iSize as Integer
Dim i as Integer

strText = "This text is a very very large."
iSize = Len(stText) / 500
ReDim arrText(iSize)
strTemp = strText

For i from 0 to iSize - 1
  arrText(i) = Left(strTemp, 500)
  strTemp = Mid(strTemp, 501)
Next i

WScript.Echo Join(strTemp, "//")
