一些很实用且必用的小脚本代码:

脚本1:进入主页以后自动播放声音
<embed src="pnm://10.13.31.90/~kayvin/mihunji.rm" hidden=true autostart=true loop=true>

脚本2:进入主页后自动最大话,省的去在自己单击了
<script>
self.moveTo(0,0)
self.resizeTo(screen.availWidth,screen.availHeight)
</script>

脚本3:显示现在时间的脚本
<script language=vbscript>document.write now</script>

脚本4:显示最后修改时间的脚本
<script>document.write(document.lastModified)</script>

脚本5:设为首页,加为收藏，加入频道,启动outlook发信
<a style="cursor:hand"　
onclick="this.style.behavior="url(#default#homepage)";
this.setHomePage(http://10.13.31.90/~kayvin/);">">设为首页</a>

<a style="cursor:hand"
onclick="window.external.AddFavorite(location.href,document.title);">加入收藏</a>

<a href=javascript:window.external.addChannel("typhoon.cdf")>加入频道</a>

<a href="mailtkayvin@sohu.com">与我联系</a>

脚本6:状态栏动态显示现在时间
<script>
function see(){
window.setTimeout("see()",1000);
today = new Date();
self.status = today.toString();
}
</script>
<body onload=see()>

脚本7:关闭窗口的脚本
<a href=javascript:close()>[关闭窗口]</a>

脚本8:按下F12键,直接返回首页
<script>function look(){
if(event.keyCode==123){document.location.href=http://10.13.31.90/~kayvin/}
}
if(document.onkeydown==null)
{document.onkeydown=look}
</script>

脚本9:后退,刷新,前进
<input type=button value=后退 onclick=history.go(-1)>

<input type=button value=刷新 onclick=history.go(-0)>

<input type=button value=前进 onclick=history.go(+1)>

脚本10:设定时间弹出窗口,4000=4秒,当然你可以自定义
<script>function l()
{
window.open(" 10.13.31.90/~kayvin/ ","name","width=500,height=150,border=0")
}
setTimeout("l()",4000)

</script>

2. 鼠标旁边的提示信息,类似与163登录后的页面提示效果

<a href="#" title="这是提示">tip</a>
<script Language="JavaScript">
//***********默认设置定义.*********************
tPopWait=50;//停留tWait豪秒后显示提示。
tPopShow=5000;//显示tShow豪秒后关闭提示
showPopStep=20;
popOpacity=99;
//***************内部变量定义*****************
sPop=null;
curShow=null;
tFadeOut=null;
tFadeIn=null;
tFadeWaiting=null;
document.write("<style type='text/css'id='defaultPopStyle'>");
document.write(".cPopText { background-color: #F8F8F5;color:#000000; border: 1px #000000 solid;font-color: font-size: 12px; padding-right: 4px; padding-left: 4px; height: 20px; padding-top: 2px; padding-bottom: 2px; filter: Alpha(Opacity=0)}");
document.write("</style>");
document.write("<div id='dypopLayer' style='position:absolute;z-index:1000;' class='cPopText'></div>");

function showPopupText(){
var o=event.srcElement;
MouseX=event.x;
MouseY=event.y;
if(o.alt!=null && o.alt!=""){o.dypop=o.alt;o.alt=""};
if(o.title!=null && o.title!=""){o.dypop=o.title;o.title=""};
if(o.dypop!=sPop) {
sPop=o.dypop;
clearTimeout(curShow);
clearTimeout(tFadeOut);
clearTimeout(tFadeIn);
clearTimeout(tFadeWaiting);
if(sPop==null || sPop=="") {
dypopLayer.innerHTML="";
dypopLayer.style.filter="Alpha()";
dypopLayer.filters.Alpha.opacity=0;
}
else {
if(o.dyclass!=null) popStyle=o.dyclass
else popStyle="cPopText";
curShow=setTimeout("showIt()",tPopWait);
}
}
}
function showIt(){
dypopLayer.className=popStyle;
dypopLayer.innerHTML=sPop;
popWidth=dypopLayer.clientWidth;
popHeight=dypopLayer.clientHeight;
if(MouseX+12+popWidth>document.body.clientWidth) popLeftAdjust=-popWidth-24
else popLeftAdjust=0;
if(MouseY+12+popHeight>document.body.clientHeight) popTopAdjust=-popHeight-24
else popTopAdjust=0;
dypopLayer.style.left=MouseX+12+document.body.scrollLeft+popLeftAdjust;
dypopLayer.style.top=MouseY+12+document.body.scrollTop+popTopAdjust;
dypopLayer.style.filter="Alpha(Opacity=0)";
fadeOut();
}
function fadeOut(){
if(dypopLayer.filters.Alpha.opacity<popOpacity) {
dypopLayer.filters.Alpha.opacity+=showPopStep;
tFadeOut=setTimeout("fadeOut()",1);
}
else {
dypopLayer.filters.Alpha.opacity=popOpacity;
tFadeWaiting=setTimeout("fadeIn()",tPopShow);
}
}
function fadeIn(){
if(dypopLayer.filters.Alpha.opacity>0) {
dypopLayer.filters.Alpha.opacity-=1;
tFadeIn=setTimeout("fadeIn()",1);
}
}
document.onmouseover=showPopupText;
</script>

3.如果文字过长,则将过长的部分变成省略号显示

<DIV STYLE="width: 120px; height: 50px; border: 1px solid blue; overflow: hidden; text-overflow:ellipsis">
<NOBR>就是比如有一行文字，很长，表格内一行显示不下.</NOBR>
</DIV>

4.接收键盘指令的脚本

<SCRIPT language="JavaScript">

</SCRIPT>

onkeydown="javascript:onenter();"

function onenter(){
if(event.keyCode==13){
alert("回车");
}
}
