ASP中一个字符串处理类（VBScript）

vbscript|字符串

这个类是用于处理字符串的，是老外写的，我把里面的功能和参数加了说明

使用方法：

=============== test.asp================

<!--#include file="StringOperations.asp"-->

<%
dim str
set str = New StringOperations
test = str.toCharArray("check this out")
response.write "<strong>str.toCharArray</strong>: "
for i = 0 to ubound(test)
response.write test(i) & " "
next

response.write "<BR><BR>"
test1 = str.arrayToString(test)
response.write "<strong>str.arrayToString</strong>: " & test1

response.write "<BR><BR>"
response.write "<strong>str.startsWith</strong>: " & str.startsWith(test1, "ch")

response.write "<BR><BR>"
response.write "<strong>str.endWith</strong>: " & str.endsWith(test1, "out")

response.write "<BR><BR>"
response.write "<strong>str.clone</strong>: " & str.clone("abc", 10)

response.write "<BR><BR>"
response.write "<strong>str.trimStart</strong>: " & str.trimStart(test1, 3)

response.write "<BR><BR>"
response.write "<strong>str.trimEnd</strong>: " & str.trimEnd(test1, 2)

response.write "<BR><BR>"
response.write "<strong>str.swapCase</strong>: " & str.swapCase("HiHiHi")

response.write "<BR><BR>"
response.write "<strong>str.isAlphabetic</strong>: " & str.isAlphabetic("!")

response.write "<BR><BR>"
response.write "<strong>str.capitalize</strong>: " & str.capitalize("clara fehler")
Set str = Nothing
%>
