asp 总结一
1.动态显示列表框内容:
<select class="wenbenkuang" name="shopxpbe_id">
<option value="0" selected>所有分类</option>
<%do while not rs.eof%>
<option value="<%=rs("shopxpbe_id")%>"><%=trim(rs("shopxpbe_name"))%></option>
<%rs.movenext
loop
rs.close
set rs=nothing%>
</select>
2.SESSION判断用户是否已经登陆
<table border="0" width="340" align="left" cellpadding="0" cellspacing="0">
<tr>
<td width="226">
</td>
<% if session("shopuser")="" then %>
<%if request.Cookies("shopxp")("username")="" or request.Cookies("shopxp")("reglx")="" then %>
<%else%>
<td bgcolor="#E7E7E7"> <font color="#FF0000"><%=request.Cookies("shopxp")("username")%></font>，<a href="xplogout.asp">退出</a></td>
<%end if%>
<%else%>
<td bgcolor="#E7E7E7"> <font color="#FF0000"><%=session("shopuser")%></font>,<a href="out.asp">退出</a></td>
<%end if%></tr>
</table>
3.图片向上滚动显示
1.
<marquee onMouseOver=this.stop() direction="up" align="left"
onMouseOut=this.start()
scrollamount="4" height="360">
<%
sqrr="select * from auctions where aucended<>'Y' and aucitemowner="& rsshop("shopownerid") &" order by aucCurrentBid DESC"
call sql_aucmm(sqrr)
%>
</marquee>
2.
Function sql_aucmm(sql)
'图片显示
response.Write(" ")
response.write"<table cellpadding=0 cellspacing=0 border=0 width=300 align=left>"
response.write"<TR valign=top width=300 height=120 >"
response.Write("<td width=150 align=center>")
set rs=server.createobject("ADODB.recordset")
rs.open sql,conn,1,1
if rs.eof or rs.bof then
response.write"<td align=center width=150>没有商品</td>"
else
i=0
Do while not rs.eof
%>
<table border="0" width="200" cellpadding="0" cellspacing="0" align="center" >
<tr>
<td rowspan="2" width="100">
<%
response.Write(" ")
call display_imgm(rs("aucid"),4)
response.Write("<br>")
%>
</td>
<td width="100">商品名称：<br>
<%
response.Write("<a href='../aucinfo.asp?aucid="&rs("aucid")&"'>")
if len(rs("aucitemtitle"))> 10 then
response.Write(left(rs("aucitemtitle"),8)&"...")
else
response.Write(rs("aucitemtitle"))
end if
response.Write("</a>")
%>
</td>
</tr>
<tr>
<td>
<%
if rs("auctype")=2 then response.write"一口价:"
%> <font color="#FF0000"><%=rs("aucCurrentBid")%></font>元</td>
</tr>
</table>
<%
i=i+1
if i>15 then
Exit Do
end if
if i mod 2 =0 then
response.Write("</td></tr><tr valign=top height=120 whidth=300><td width=100 align=center>")
else
response.Write("</td><td width=120>")
end if
rs.MoveNext
rs.close
set rs=nothing
end if
response.write"</TR>" & vbcrlf
response.write"</table>" & vbcrlf
End Function
(4) QQ再线交谈
1. 显示QQ连接图片和函数
<%call Display_userqq(rs ("userqq"))%>
2.函数内容
Function Display_userqq(qqnum)
response.write"<a target=blank href=http://wpa.qq.com/msgrd?V=1&Uin="&qqnum&"&Site="&SYS_WEBNAME&"><img border=""0"" SRC=http://wpa.qq.com/pa?p=1:"&qqnum&":3 alt=""联系卖家QQ""></a>"
End Function
(5) MD5密码加密
1. 引入加密文件: <!--#include file="usershopxp/md5.asp"-->
2. 注册加密: rs("userpassword")=md5(trim(request("userpassword")))
(6 ) 截取前几个字符显示标题
1. <table border="0" cellpadding="0" cellspacing="0" width="198">
<%
set rs=server.CreateObject("adodb.recordset")
rs.open "select Top 15 * from shops where shoptuijian=1 order by shopregtime ",conn,1,1
do while not rs.eof
%>
<tr height="20">
<td width="197" height="20" align="left" valign="middle"><img src="image/t_03.jpg" width="13" height="14" border="0" /><a href="dianpu.asp?shopid=<%=rs("shopid")%>">
<% if len(rs("shop_name"))>8 then
response.Write(left(rs("shop_name"),8))
else
response.Write(rs("shop_name"))
end if
%>
</a><font color="#999999">(</font><font color="#FF0000"><%=rs("shopclick")%></font><font color="#0099FF">↑</font><font color="#999999">)</font></td>
</tr>
<%
rs.movenext
loop
rs.close
set rs=nothing
%>
</table>
2. <% if len(trim(rs("shopxpptname")))>20 then
response.write left(trim(rs("shopxpptname")),18)&".."
else
response.write trim(rs("shopxpptname"))
end if%>
(6) 验证码的实现 （原文件: GetshopxpCode.asp）
1. <td width="40%" align="right">验证码：</td>
<td width="60%"><input class=wenbenkuang name=verifycode type=text value="<%If GetCode=9999 Then Response.Write "9999"%>" maxLength=4 size=10>
<img src=GetshopxpCode.asp> </td>
（7）网页中弹出窗口
<script language="javascript" >
window.open ('dv.html', 'newwindow', 'height=524, width=745, top=5, toolbar=no, menubar=no, scrollbars=no, resizable=no,location=no, status=no')
/*window.open ('tuangou.html', 'newwindow2', 'height=660, width=760, top=20,left=10, toolbar=no, menubar=no, scrollbars=yes, resizable=no,location=no, status=no') */
</script>
(8) 弹出内容(窗口)
<a href="javascript:;" onClick="javascript:window.open('viewnimingdingdan.asp?dan=<%=trim(rs("dingdan"))%>&username=<%=username%>','','width=710,height=388,toolbar=no, status=no, menubar=no, resizable=yes, scrollbars=yes');return false;"><%=trim(rs("dingdan"))%></a>
(9) 选择列表框选择出发事件
<select name="select" onChange="var jmpURL=this.options[this.selectedIndex].value ; if(jmpURL!='') {window.location=jmpURL;} else {this.selectedIndex=0 ;}" ><base target=Right>
<option value="editnimingdingdan.asp?zhuangtai=0" selected>--选择查讯状态--</option>
<option value="editnimingdingdan.asp?zhuangtai=0" >全部订单状态</option>
<option value="editnimingdingdan.asp?zhuangtai=1" >未作任何处理</option>
<option value="editnimingdingdan.asp?zhuangtai=2" >用户已经划出款</option>
<option value="editnimingdingdan.asp?zhuangtai=3" >服务商已经收到款</option>
<option value="editnimingdingdan.asp?zhuangtai=4" >服务商已经发货</option>
<option value="editnimingdingdan.asp?zhuangtai=5" >用户已经收到货</option>
</select>
