Javascript 中的 一些很实用且必用的小脚本代码

出处:互联网   整理: 软晨网（RuanChen.com）   发布: 2009-09-12   浏览: 141 ::
收藏到网摘: n/a

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://ruanchen.com/">">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=[email protected]>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>

脚本11: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。

document.write("</style>");
document.write("<div id='dypopLayer' style='position:absolute;z-index:1000;' class='cPopText'></div>");
function showPopupText(){
var o=event.srcElement;

function fadeIn(){
if(dypopLayer.filters.Alpha.opacity>0) {
dypopLayer.filters.Alpha.opacity-=1;
tFadeIn=setTimeout("fadeIn()",1);
}
}
document.onmouseover=showPopupText;
</script>

脚本12：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>
