1.分 类：语法应用
问题描述：查找两个字符串间的字符出现次数
解决办法：
function FindStringTimes(strContent,start_string,end_string) ‘start_string 与 end_string 之间字符出次的数
‘written by Jaron
FindStringTimes = ubound(split(strContent,start_string))
end function
示例： 查找以下字符串有多少张图片
response.write FindStringTimes(HTML,"<img",">")
<img src="http://jc.upschool.cn/upload/2006-12-20/20061220932477053.jpg"><img src="http://jc.upschool.cn/upload/2006-12-20/20061220932483737.jpg"><img src="http://jc.upschool.cn/upload/2006-12-20/20061220932442720.jpg"><img src="http://jc.upschool.cn/upload/2006-12-20/20061220932498471.jpg">
2.遍历目录以及目录下文件的函数
<%
function bianli(path)
set fso=server.CreateObject("scripting.filesystemobject")
on error resume next
set objFolder=fso.GetFolder(path)
set objSubFolders=objFolder.Subfolders
for each objSubFolder in objSubFolders
nowpath=path + "\" + objSubFolder.name
Response.Write nowpath
set objFiles=objSubFolder.Files
for each objFile in objFiles
Response.Write "<br/>---"
Response.Write objFile.name
next
Response.Write "<p>"
bianli(nowpath)‘递归
next
set objFolder=nothing
set objSubFolders=nothing
set fso=nothing
end function
%>
<%
bianli("d:") ‘遍历d:盘
%>
3.生成一个不重复的随即数字
Sub CalCaPiao()
Dim strCaiPiaoNoArr() As String
Dim strSQL As String
Dim strCaiPiaoNo As String
strCaiPiaoNo = "01,02,03,04,05,06,07,08,09,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33"
Dim StrTempArr(7) As String
Dim strZhongJiangArr(7) As String
strCaiPiaoNoArr = Split(strCaiPiaoNo, ",")
Dim intRand As Integer
Dim i As Integer
Dim j As Integer
i = 0
Dim find As Boolean
Do While True
find = False
Randomize
intRand = Int((33 * Rnd) + 1)
For j = 0 To i - 1
If StrTempArr(j) = CStr(intRand) Then
find = True
End If
Next
If Not find Then
StrTempArr(j) = CStr(intRand)
strZhongJiangArr(i) = CStr(intRand)
‘Text1(i) = strZhongJiangArr(i)
i = i + 1
If i = 7 Then
Exit Do
End If
End If
Loop
End Sub
4.下载任何文件（尤其是IE关联打开的）
<%
Dim Stream
Dim Contents
Dim FileName
Dim FileExt
Const adTypeBinary = 1
FileName = Request.QueryString("FileName")
if FileName = "" Then
Response.Write "无效文件名."
Response.End
End if
‘ 下面是不希望下载的文件
FileExt = Mid(FileName, InStrRev(FileName, ".") + 1)
Select Case UCase(FileExt)
Case "ASP", "ASA", "ASPX", "ASAX", "MDB"
Response.Write "受保护文件,不能下载."
Response.End
End Select
‘ 下载这个文件
Response.Clear
Response.ContentType = "application/octet-stream"
Response.AddHeader "content-disposition", "attachment; filename=" & FileName
Set Stream = server.CreateObject("ADODB.Stream")
Stream.Type = adTypeBinary
Stream.Open
Stream.LoadFromFile Server.MapPath(FileName)
While Not Stream.EOS
Response.BinaryWrite Stream.Read(1024 * 64)
Wend
Stream.Close
Set Stream = Nothing
Response.Flush
Response.End
%>
5.背景色变换
<form>
<p><input TYPE="button" value="背景色变换" onClick="BgButton()"></p>
</form>
<script>function BgButton(){
if (document.bgColor==#00ffff)
{document.bgColor=#ffffff;}
else{document.bgColor=#00ffff;}
}
</script>
6.点击打开新窗口
<form>
<p><input TYPE="button" value="打开新窗口" onCLICK="NewWindow()"></p>
</form>
<script language="javascript"><!--
function NewWindow(){window.open("http://www.mcmx.com";;;;,"","height=240,width=340,status=no,location=no,toolbar=no,directories=no,menubar=no");}
// --></script></body>
||||||7.分页代码:
<%本程序文件名为：Pages.asp%>
<%包含ADO常量表文件adovbs.inc，可从"\Program Files\Common Files\System\ADO"目录下拷贝%>
<!--#Include File="adovbs.inc"-->
<%＊建立数据库连接，这里是Oracle8.05数据库
Set conn=Server.CreateObject("ADODB.Connection")
conn.Open "Provider=msdaora.1;Data Source=YourSrcName;User ID=YourUserID;Password=YourPassword;"
Set rs=Server.CreateObject("ADODB.Recordset") 创建Recordset对象
rs.CursorLocation=adUseClient 设定记录集指针属性
＊设定一页内的记录总数，可根据需要进行调整
rs.PageSize=10
＊设置查询语句
StrSQL="Select ID,姓名,住址,电话 from 通讯录 Order By ID"
rs.Open StrSQL,conn,adOpenStatic,adLockReadOnly,adCmdText
%>
<HTML>
<HEAD>
<title>分页示例</title>
<script language=javascript>
//点击"[第一页]"时响应：
function PageFirst()
{
document.MyForm.CurrentPage.selectedIndex=0;
document.MyForm.CurrentPage.onchange();
}
//点击"[上一页]"时响应：
function PagePrior()
{
document.MyForm.CurrentPage.selectedIndex--;
document.MyForm.CurrentPage.onchange();
}
//点击"[下一页]"时响应：
document.getElementById('loading').style.display="none";
