1.'功能: 过虑HTML字符
'输入:字符串
'输出:经格式化后的字符串
function HTMLEncode(fString)
if not isnull(fString) then
fString = replace(fString, ">", ">")
fString = replace(fString, "<", "<")

fString = Replace(fString, CHR(32)&CHR(32), "  ")
fString = Replace(fString, CHR(9), " ")
fString = Replace(fString, CHR(34), """)
fString = Replace(fString, CHR(39), "'")
fString = Replace(fString, CHR(13), "")

3.如何在客户端无刷新调用服务端代码
1.<iframe src="ifm.asp?param=??"></iframe>
2.xmlhttp:
dim objXMLHTTP

set objXMLHTTP=CreateObject("MICROSOFT.XMLHTTP")

objXMLHTTP.open "GET","xmlhttp.asp",false
'参数1:post,get;参数2:请求的URL, 参数3:同步或异步调用

objXMLHTTP.send ""
magbox objXMLHTTP.ResponseText '服务端输出到客户端的文本数据
------------
xmlhttp:参考
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/xmlsdk30/htm/xmobjxmlhttprequest.asp

5.分页类

'===========================================================
'分页类,大体思想由.Net的DataGrid的使用方式而来
'功能:自动生成datagrid列表头和内容,以及分页栏
'根据网友bubuy (澎湃 NoMoneyToBuy)得分页函数修改成类
'使用示例:
'dim DG
'dim Url
'dim Fld(2)
'dim FldName(2)
'dim FldWidth(2)
'Fld(0) = "ID"
'Fld(1) = "Title"
'Fld(2) = "Input_Date"
'FldName(0) = "编号"
'FldName(1) = "标题"
'FldName(2) = "录入日期"
'FldWidth(0) = "10%"
'FldWidth(1) = "60%"
'FldWidth(2) = "30%"
'set DG = new DataGrid
'DG.DataSource = rs_Grid
'DG.titleColor = "#DCE19D"
'DG.PageSize = 1
'DG.Fields = Fld
'DG.FieldsName = FldName
'DG.fieldWidth = FldWidth

'DG.Url = Url
