滚动条在左侧,将<html>改为<HTML DIR="RTL">
====================================================================================================
网页半透明
<body style="filter:Alpha(Opacity=50)">
随机选择背景色
<body>
<script>
document.body.style.background=(["red","blue","pink","navy","gray","yellow","green","purple"])[parseInt(Math.random()*8)];
</script>
框架页中不显示滚动条：
<SCRIPT>
self.moveTo(0,0)
self.resizeTo(screen.availWidth,screen.availHeight)
</SCRIPT>
防止网页被框架
<SCRIPT LANGUAGE=JAVASCRIPT>
if (top.location !== self.location) {
top.location=self.location;
}
</SCRIPT>
永远都会带着框架
<script language="javascript"><!--
if (window == top)top.location.href = "frame.htm"; //frame.htm为框架网页
// --></script>
窗口自动最大化
<script language="JavaScript"><!--
self.moveTo(0,0)
self.resizeTo(screen.availWidth,screen.availHeight)
//--></script>
打开窗口自动最大化
<OBJECT classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11" onreadystatechange="if (this.readyState==4) this.Click();" VIEWASTEXT><PARAM name="Command" value="Maximize"></OBJECT>
爽眼闪屏代码
<script>var color = new Array;color[1] = "black";color[2] = "white";for(x = 0; x <3; x++){document.bgColor = color[x];if(x == 2){x = 0;}}</script>
不能被另存为
<noscript><iframe src="*.html"></iframe></noscript>
汉字字库调用
<script>
for(i=19968;i<40870;i++)document.write(String.fromCharCode(i));
</script>
显示现在时间的脚本
<script language=vbscript>document.write now</script>
显示最后修改时间的脚本
<script>document.write(document.lastModified)</script>
按下F12键,直接返回首页
<script>function look(){
if(event.keyCode==123){document.location.href=http://www.winliuxq.com/}
}
if(document.onkeydown==null)
{document.onkeydown=look}
</script>
端口检测
<img src="http://www.winliuxq/zza.jpg" onload="alert('端口可用')" onerror="alert('端口禁止')"...>
无法最小化的窗口
<body onblur='self.focus();'>
链接点外部css文件
<style>@import url("ie.css");</style>
内嵌式框架-网页中调用另外网页：
<object type="text/x-scriptlet" width="600" height="1000" data="http://www.winliuxq.com/"></object>
刷新改变窗口大小
<OBJECT classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11" onreadystatechange="if (this.readyState==4) this.Click();" VIEWASTEXT><PARAM name="Command" value="Maximize"></OBJECT>
JavaScript实现网页竖虚线
<script>hei=120;d1=2;d2=2;cou=Math.floor(hei/(d1+d2));
document.write('<table cellspacing=0 cellpadding=0 width=1 height='+hei+'>');
for(i=0;i<cou;i++){document.write('<tr><td height='+d2+'><tr><td height='+d1+' bgcolor=333333>')}</script></table>
js翻页
<script>document.write("<a href="+location.href.replace(/\.html/g,"_2.html")+">2</a>");</script>
