vbscript - 如何在vbscript中对文本进行子串

Question

我正在使用 VBScript

我有下面的文字

str = "tcm:1-245-9"

现在我想以这种方式在字符串上方进行子串，以便得到如下输出
pstr = "245"从上面的字符串，

请让我知道仅在 VBScript 中的建议。

Answer 1

您可以使用

Mid(string,start[,length]) 

string - Required. The string expression from which characters are returned

start  - Required. Specifies the starting position. If set to greater than the number of characters in string, it returns an empty string ("")

length  - Optional. The number of characters to return

或使用

Split(expression[,delimiter[,count[,compare]]]) 

expression - Required. A string expression that contains substrings and delimiters

delimiter  - Optional. A string character used to identify substring limits. Default is the space character

count      - Optional. The number of substrings to be returned. -1 indicates that all substrings are returned

compare    - Optional. Specifies the string comparison to use.

            Can have one of the following values:
              * 0 = vbBinaryCompare - Perform a binary comparison
              * 1 = vbTextCompare - Perform a textual comparison
