一些ASP技巧和實用解決方法
隨機數:
<%randomize%>
<%=(int(rnd()*n)+1)%>
查詢數據時得到的記錄關鍵字用紅色顯示：
<% =replace(RS("字段X"),searchname,"<font color=#FF0000>" & searchname & "</font>") %>
通過asp的手段來檢查來訪者是否用了代理
<% if Request.ServerVariables("HTTP_X_FORWARDED_FOR")<>"" then
response.write "<font color=#FF0000>您通過了代理服務器，"& _
"真實的IP為"&Request.ServerVariables("HTTP_X_FORWARDED_FOR")
end if
%>
判斷上一頁的來源
request.servervariables("HTTP_REFERER")
javascript: document.referrer
清除緩存，重新加載頁面
<%response.expires = 0
response.expiresabsolute = now() - 1
response.addHeader "pragma","no-cache"
response.addHeader "cache-control","private"
Response.cachecontrol = "no-cache"
%>
在下拉菜單中顯示年和月
<select name="select">
<%
Dim M_Year
Dim M_Month
Dim M_MonthJ
Dim M_TheMonth
Dim M_YM
For M_Year = 2000 To Year(Date)
M_Month = 12
If M_Year = Year(Date) Then
M_Month = Month(Date)
End If
For M_MonthJ=1 To M_Month
If M_MonthJ < 10 Then
M_TheMonth = "0" & M_MonthJ
Else
M_TheMonth = M_MonthJ
End If
M_YM = M_Year& "-" & M_TheMonth %>
<option value="<%= M_YM %>"><%= M_YM %></option>
<%
Next
Next %>
</select>
檢索並刪除數據庫裡的重復記錄
conn.execute("delete from table where id not in (select distinct from table)")
