這個類是用於處理字串的,是老外寫的,我把裡面的功能和參數加了說明
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)
