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 %>
