How to Auto Include a Javascript File 最新优化收藏到网摘代码（digg，diigo）

1. 每条文字信息循环显示，

点击运行可以看到效果:
[Ctrl+A 全选提示:你可先修改部分代码,再按运行]

2.逐行显示文字,转换过程中带有渐隐渐显效果

点击运行可以看到效果:

以下代码加入<head>区域
<style type="text/css">
#tic { /* enter any styles for the ticker below */ border: .05em #CEC3AD solid; font-size:0.85em; padding:10px; width:400px; line-height:20px;
}
#tic * { /* this will hide all children tags */ font-size: 1em; margin:0px; padding:0px; display:none;
}
#tic a { /* add more tags to this list if you wish to display them inside the children */ display:inline;
}
</style>
<script type="text/javascript">
//more javascript from <img src="images/link.gif" border="0" /><a
href="http://www.smallrain.net" target="_blank">http://www.smallrain.net</a>
var list; // global list variable cache
var tickerObj; // global tickerObj cache
var hex = 255;
function fadeText(divId) { if(tickerObj) { if(hex>0) { hex-=5; // increase color darkness tickerObj.style.color="rgb("+hex+","+hex+","+hex+")"; setTimeout("fadeText('" + divId + "')", fadeSpeed); } else hex=255; //reset hex value }
}
function initialiseList(divId) { tickerObj = document.getElementById(divId); if(!tickerObj) reportError("Could not find a div element with id \"" + divId + "\""); list = tickerObj.childNodes; if(list.length <= 0) reportError("The div element \"" + divId + "\" does not have any children"); for (var i=0; i<list.length; i++) { var node = list[i]; if (node.nodeType == 3 && !/\S/.test(node.nodeValue)) tickerObj.removeChild(node); } run(divId, 0);
}
function run(divId, count) { fadeText(divId); list[count].style.display = "block"; if(count > 0) list[count-1].style.display = "none"; else list[list.length-1].style.display = "none"; count++; if(count == list.length) count = 0; window.setTimeout("run('" + divId + "', " + count+ ")", interval*1000);
}
function reportError(error) { alert("The script could not run because you have errors:\n\n" + error); return false;
}
var interval = 7; // interval in seconds
var fadeSpeed = 40; // fade speed, the lower the speed the faster the fade. 40 is normal.
</script>
以下代码加入<body>区域
<div id="tic">
<h1>什么是ASP？</h1>
Ａｃｔｉｖｅ　Ｓｅｒｖｅｒ　Ｐａｇｅｓ（ASP，活动服务器页面）就是一个编程环境，在其中，可以
混合使用HTML、脚本语言以及组件来创建服务器端功能强大的Internet应用程序。 如果你以前创建过一个站点，其中混合了HTML、脚本语言以及组件，你就可以在其中加入ASP程序代码。
通过在HTML页面中加入脚本命令，你可以创建一个HTML用户界面，并且，还可以通过使用组件包含一些商
业逻辑规则。
组件可以被脚本程序调用，也可以由其他的组件调用。
<h2>什么是 ASP.NET？</h2>
ASP.NET 是建立在公共语言运行库上的编程框架，可用于在服务器上生成功能强大的 Web 应用程序。
与以前的 Web 开发模型相比，ASP.NET 提供了数个重要的优点：增强的性能、世界级的工具支持、威力
和灵活性、简易性、可管理性、可缩放性和可用性、自定义性和扩展性、安全性。
<h2>什么是PHP？</h2>
PHP 是一种用来制作动态网页的服务器端脚本语言。你通过PHP和HTML创建页面。当访问者打开网页时，
服务器端便会处理 PHP 指令，然后把其处理结果送到访问者的浏览器上面，就好像 ASP 或者是
ColdFusion 一样。然而，PHP 跟 ASP 或 ColdFusion 不一样的地方在于，它是跨平台的开放源代码。

6.加亮卷动是在视觉上引起兴趣,多次卷动。它逐渐地将每个信息进从底部升到顶端的视线中,是显示文本的一种好方法。

////Do not edit pass this line////////////////
var ie4=document.all&&navigator.userAgent.indexOf("Opera")==-1
var ns6=document.getElementById&&navigator.userAgent.indexOf("Opera")==-1
var ns4=document.layers
var currentmessage=0
var tickercontentstotal=''
function changetickercontent(){
if (ns4){
tickerobj.document.tickernssub.document.write('<b><a href="#" onClick="return expandlist
(event)">显/隐</a></b> | '+tickercontents[currentmessage])
tickerobj.document.tickernssub.document.close()
}
else if (ie4||ns6){
tickerobj.innerHTML=tickercontents[currentmessage]

tickerexpand_item.className="expandhighlight"
}
currentmessage=(currentmessage==tickercontents.length-1)? 0 : currentmessage+1
setTimeout("changetickercontent()",tickdelay)
}
function start_ticking(){
if (ns4) document.tickernsmain.visibility="show"

visibility=hide><layer id="tickernssub" width=&{tickerwidth}; left=0 top=0></layer></ilayer>
<layer id="expandlayer" bgColor=&{tickerbgcolor}; visibility=hide></layer>

7.在文字转换间加上了类似灯光遮照的效果
以下代码加入<head>区域<SCRIPT>

</SCRIPT>以下代码加入<body>区域<table height=45 cellspacing=1 cellpadding=1 width="80%"
bgcolor=#000000 border=0 align="center">
<tbody>
<tr>
<td bgcolor=#D7E4F2>
<div align=center>

</script>

<span
id=temp style="LEFT: 0px; POSITION: absolute; TOP: 0px">
</span>　 </div>
</td>
</tr>
</tbody>
</table>

8.文字一段一段的显示，每次交换时都带有渐隐渐显的效果
