ASP技巧集锦1

1.如何最小化、最大化、关闭窗口
答：<objectid=hh1classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<paramname="command"value="minimize"></object>

1.如何最小化、最大化、关闭窗口
答：<objectid=hh1classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<paramname="command"value="minimize"></object>
<objectid=hh2classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<paramname="command"value="maximize"></object>
<objectid=hh3classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<paramname="command"value="close"></object>

<inputtype=buttonvalue=最小化onclick=hh1.click()>
<inputtype=buttonvalue=最大化onclick=hh2.click()>
<inputtype=buttonvalue=关闭onclick=hh3.click()>

2.如何静止页面缓存
答：htm网页
<metahttp-equiv="pragma"content="no-cache">
<metahttp-equiv="cache-control"content="no-cache,must-revalidate">
<metahttp-equiv="expires"content="wed,26feb199708:21:57gmt">
或者<metahttp-equiv="expires"content="0">
asp网页
response.expires=-1
response.expiresabsolute=now()-1
response.cachecontrol="no-cache"
php网页
header("expires:mon,26jul199705:00:00gmt");
header("cache-control:no-cache,must-revalidate");
header("pragma:no-cache");

3.如何检查一段字符串是否全由数字组成
<scriptlanguage="javascript"></script>

4.如何获取机器信息
答本机ip<%=request.servervariables("remote_addr")%>
服务器名<%=request.servervariables("server_name")%>
服务器ip<%=request.servervariables("local_addr")%>
服务器端口<%=request.servervariables("server_port")%>
服务器时间<%=now%>
iis版本<%=request.servervariables"server_software")%>
脚本超时时间<%=server.scripttimeout%>
本文件路径<%=server.mappath(request.servervariables("script_name"))%>
服务器cpu数量<%=request.servervariables("number_of_processors")%>
服务器解译引擎<%=scriptengine&"/" & scriptenginemajorversion &"." & scriptengineminorversion & "." & scriptenginebuildversion%>
服务器操作系统<%=request.servervariables("os")%>1.如何让日期相减
日期减去天数等于第二个日期
<scriptlanguage=javascript>
functioncc(dd,dadd)
{
file://可以加上错误处理
vard=newdate(dd.replace("-","/"))
d.setdate(d.getdate()+dadd)
alert(d.getfullyear()+"年"+(d.getmonth()+1)+"月"+d.getdate()+"日")
}
cc("2002-2-28",2)
</script>

1.怎样通过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
%>

获得窗口的大小
document.body.clientWidth,document.body.clientHeight
document.body.offsetWidth,document.body.offsetHeight

判断一个表是否存在：
if exists (select * from dbo.sysobjects where id = object_id(‘表名‘) and OBJECTPROPERTY(id, N‘IsUserTable‘) = 1)
drop table 表名
GO
从publish 表中取出第 n 条到第 m 条的记录：
SELECT TOP m-n+1 *
FROM publish
WHERE (id NOT IN
　　　　　 (SELECT TOP n-1 id
　　　　 FROM publish))

id 为publish 表的关键字

1.如何实现连续滚动

数据里面读出来的<br/>
</div>

marqueesHeight=200;
stopscroll=false;

with(marquees){
style.width=0;
style.height=marqueesHeight;
style.overflowX="visible";
style.overflowY="hidden";
noWrap=true;
onmouseover=new Function("stopscroll=true");
onmouseout=new Function("stopscroll=false");
}
document.write(‘<div id="templayer" style="position:absolute;z-index:1;visibility:hidden"></div>‘);

preTop=0; currentTop=0;

function init(){
templayer.innerHTML="";
while(templayer.offsetHeight<marqueesHeight){
templayer.innerHTML+=marquees.innerHTML;
}
marquees.innerHTML=templayer.innerHTML+templayer.innerHTML;
setInterval("scrollUp()",10);
}
document.body.onload=init;

function scrollUp(){
if(stopscroll==true) return;
preTop=marquees.scrollTop;
marquees.scrollTop+=1;
if(preTop==marquees.scrollTop){
marquees.scrollTop=templayer.offsetHeight-marqueesHeight;
marquees.scrollTop+=1;
}
}
</script>

只针对图片:
<form name=form1 onsubmit="return mm()">
<input type=file name=meizz><br/>
<input type=submit value=submit></form>

1. oncontextmenu="window.event.returnvalue=false" 将彻底屏蔽鼠标右键
<table border oncontextmenu=return(false)><td>no</table> 可用于Table

2. <body onselectstart="return false"> 取消选取、防止复制

3. onpaste="return false" 不准粘贴

4. oncopy="return false;" oncut="return false;" 防止复制

5. <link rel="Shortcut Icon" href="favicon.ico"> IE地址栏前换成自己的图标

6. <link rel="Bookmark" href="favicon.ico"> 可以在收藏夹中显示出你的图标

7. <input style="ime-mode:disabled"> 关闭输入法

8. 永远都会带着框架
<script language="javascript"></script>

9. 防止被人frame
<SCRIPT LANGUAGE=javascript></SCRIPT>

10. <noscript><iframe src=*.html></iframe></noscript> 网页将不能被另存为

11. <input type=button value=查看网页源代码
onclick="window.location = ‘view-source:‘+ ‘http://www.csdn.net/‘">

12. 怎样通过asp的手段来检查来访者是否用了代理
<% if Request.ServerVariables("HTTP_X_FORWARDED_FOR")<>"" then
response.write "<font color=#FF0000>您通过了代理服务器，"& _
"真实的IP为"&Request.ServerVariables("HTTP_X_FORWARDED_FOR")
end if
%>

13. 取得控件的绝对位置

file://javascript
<script language="javascript">
function getIE(e){
var t=e.offsetTop;
var l=e.offsetLeft;
while(e=e.offsetParent){
t+=e.offsetTop;
l+=e.offsetLeft;
}
alert("top="+t+"\nleft="+l);
}
</script>

file://VBScript
<script language="VBScript"></script>

14. 光标是停在文本框文字的最后
<script language="javascript">
function cc()
{
var e = event.srcElement;
var r =e.createTextRange();
r.moveStart(‘character‘,e.value.length);
r.collapse(true);
r.select();
}
</script>
<input type=text name=text1 value="123" onfocus="cc()">

15. 判断上一页的来源
asp:
request.servervariables("HTTP_REFERER")

javascript:
document.referrer

图片显示控制：
<script language="JavaScript">

</script>

调用格式：
<img src="a.gif" onload="javascript:DrawImage(this);"

用asp把doc转换成html
doc2html.vbs
