一些Asp技巧和实用解决方法
随机数:
<%randomize%>
<%=(int(rnd()*n)+1)%>
查询数据时得到的记录关键字用红色显示：
<%=replace(RS("字段X"),searchname,"<fontcolor=#FF0000>"&searchname&"</font>")%>
通过asp的手段来检查来访者是否用了代理
<%ifRequest.ServerVariables("HTTP_X_FORWARDED_FOR")<>""then
response.write"<fontcolor=#FF0000>您通过了代理服务器，"&_
"真实的IP为"&Request.ServerVariables("HTTP_X_FORWARDED_FOR")
endif
%>
判断上一页的来源
request.servervariables("HTTP_REFERER")
javascript:document.referrer
清除缓存，重新加载页面
<%response.expires=0
response.expiresabsolute=now()-1
response.addHeader"pragma","no-cache"
response.addHeader"cache-control","private"
Response.cachecontrol="no-cache"
%>
在下拉菜单中显示年和月
<selectname="select">
<%
DimM_Year
DimM_Month
DimM_MonthJ
DimM_TheMonth
DimM_YM
ForM_Year=2000ToYear(Date)
M_Month=12
IfM_Year=Year(Date)Then
M_Month=Month(Date)
EndIf
ForM_MonthJ=1ToM_Month
IfM_MonthJ<10Then
M_TheMonth="0"&M_MonthJ
Else
M_TheMonth=M_MonthJ
EndIf
M_YM=M_Year&"-"&M_TheMonth%>
<optionvalue="<%=M_YM%>"><%=M_YM%></option>
<%
