這個類是用於處理字符串的,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)
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
