url=Request.CurrentExecutionFilePath.ToString()
1、返回上一顿br /> <a href=javascript:history.go(-1)>返回上一顿lt;/a>
1、自动清穿br /> <input name="homepage" size="30" maxlength="100" class="editbox1" value="http://" onMouseOver="this.focus()" onMouseOut="if(this.value=='')this.value='http://';" onFocus="this.select()" onClick="if(this.value=='http://')this.value=''" onblur="if(this.value=='')this.value='站内搜索'">
1.'将发言进行编码，使其不支持 HTML 语法
says = Server.HTMLEncode(says)

function scrollwindow()
{currentpos=document.body.scrollTop;
window.scroll(0,++currentpos);
if (currentpos != document.body.scrollTop)
sc();
}

38.页面进入和退出的特效
进入页面<meta http-equiv="Page-Enter" content="revealTrans(duration=x, transition=y)">
推出页面<meta http-equiv="Page-Exit" content="revealTrans(duration=x, transition=y)">
这个是页面被载入和调出时的一些特效。duration表示特效的持续时间，以秒为单位。transition表示使用哪种特效，取值为1-23:
0 矩形缩小
1 矩形扩大
2 圆形缩小
3 圆形扩大
4 下到上刷斿

13.取得控件的绝对位罿/p>
//javascript
<scriptlanguage="javascript">
functiongetIE(e){
vart=e.offsetTop;
varl=e.offsetLeft;
while(e=e.offsetParent){
t+=e.offsetTop;
l+=e.offsetLeft;
}
alert("top="+t+"\nleft="+l);
}
</script>
//VBScript
<scriptlanguage="VBScript"><!--
functiongetIE()
dimt,l,a,b
seta=document.all.img1
t=document.all.img1.offsetTop
l=document.all.img1.offsetLeft
whilea.tagName<>"BODY"
seta=a.offsetParent
t=t+a.offsetTop
l=l+a.offsetLeft
wend
msgbox"top="&t&chr(13)&"left="&l,64,"得到控件的位罿quot;
endfunction
--></script>
14.光标是停在文本框文字的最吿br /> <scriptlanguage="javascript">
function cc()
{
vare=event.srcElement;
varr=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
16.最小化、最大化、关闭窗叿br /> <objectid=hh1classid="clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11">
<paramname="Command"value="Minimize"></object>
