Q: 实现双击自动滚屏.
A: 将以下代码添加到需要自动滚屏的页面上

<s cript Language="Javas cript">
var currentpos, timer;
function initialize(){
timer = setInterval("scrollwindow()", 1);
}
function sc(){
clearInterval(timer);
}
function scrollwindow(){
currentpos = document.body.scrollTop;
window.scroll(0, ++currentpos);
if(currentpos != document.body.scrollTop){
sc();
}
}
document.onmousedown = sc;
document.ondblclick = initialize;
</s cript>

Q: 鼠标特效 。
A: 鼠标放到链接上就会出现一个说明框，里面有滚动的文字说明

<a href="http://xiaoguo001.nease.net" target="_blank" onMouseOver="helpor_net_show(this,event,' 这里是小郭的个人主页 ')" onMouseOut="helpor_net_hide()"> 把鼠标放上来试试
<div id="tooltip2" style="position:absolute;visibility:hidden;clip:rect(0 150 50 0);width:150px;background-color:seashell">
<layer name="nstip" width="1000px" bgColor="seashell"></layer>
</div>
<SCRIPT language="JavaScript">
<!--
if (!document.layers&&!document.all)
event="test"
function helpor_net_show(current,e,text){

if (document.all&&document.readyState=="complete"){
document.all.tooltip2.innerHTML='<marquee style="border:1px solid #3399ff">'+text+'</marquee>'
document.all.tooltip2.style.pixelLeft=event.clientX+document.body.scrollLeft+10
document.all.tooltip2.style.pixelTop=event.clientY+document.body.scrollTop+10
document.all.tooltip2.style.visibility="visible"
}

else if (document.layers){
document.tooltip2.document.nstip.document.write(' '+text+' ')
document.tooltip2.document.nstip.document.close()
document.tooltip2.document.nstip.left=0
currentscroll=setInterval("scrolltip()",100)
document.tooltip2.left=e.pageX+10
document.tooltip2.top=e.pageY+10
document.tooltip2.visibility="show"
}
}
function helpor_net_hide(){
if (document.all)
document.all.tooltip2.style.visibility="hidden"
else if (document.layers){
clearInterval(currentscroll)
document.tooltip2.visibility="hidden"
}
}

function scrolltip(){
if (document.tooltip2.document.nstip.left>=-document.tooltip2.document.nstip.document.width)
document.tooltip2.document.nstip.left-=5
else
document.tooltip2.document.nstip.left=150
}
//-->
</SCRIPT>

Q: 文本随机输出，可以用来作公告栏 。
A: 脚本说明 :
第一步 : 把如下代码加入 <head> 区域中
<SCRIPT LANGUAGE="JavaScript">
<!-- Original: Tarjei Davidsen (the@rescueteam.com) -->

<!-- This script and many more are available free online at -->
<!-- The JavaScript Source!! http://javascript.internet.com -->

<!-- Begin
var max=0;
function textlist() { i++:textlist.arguments[i]; max }
tl = new textlist(
" 随着 INTERNET 时代的逐步到来 , 人们对网络的认识与感知越来越深刻 ",
" 上网主要是进行 web 页面浏览，所以 web 页面的精彩程度对一个网站的生 ",
" 人通过制作个人主页展现自己的才华，而且，由于出现了多种制作网页的软件 ",
" 但是，光用软件就成制作出你想要的各种页面效果吗？答案肯定是否定的但是，光用软件就成制作出你想要的各种页面效果吗？答案肯定是否定的 ",
"JavaScript 是 Netscape( 网景 ) 公司首先推出的一种针对 WEB 页面的解释型语 "
);

var x = 0; pos = 0;
var l = tl[0].length;
function textticker() {
document.tickform.tickfield.value = tl[x].substring(0, pos) + "_";
if(pos++ == l) {
pos = 0;
setTimeout("textticker()", 2000);
if(++x == max) x = 0;
l = tl[x].length;
} else
setTimeout("textticker()", 50);
}
// End -->
</script>
</HEAD>


第二步 : 把如下代码加入 <body> 区域中
<form name=tickform>
<textarea name=tickfield rows=3 cols=38 style="background-color: rgb(0,0,0); color: rgb(255,255,255); cursor: default; font-family: Arial; font-size: 12px" wrap=virtual>The news will appear here when the page has finished loading.
</textarea>
</form>


第三步 : 把 <body> 改为
<body bgcolor="#fef4d9" OnLoad="textticker()">

Q: 进入页面自动弹出的欢迎致词，个人网站可加......
A: 今天在公司网站上抓的，进入页面自动弹出的欢迎致词，个人网站可加上不免没有加好呀。加的位置应该可以看懂吧。
<html>
<head>
</head>
<body>
</body>
<script language="vbscript">
<!--
MsgBox"欢迎光临我的网站！"
-->
</script>
</html>

Q: 页面自动刷新说明 。
A: 当你做网页时，是不是有的时候想让你的网页自动不停刷新，或者过一段时间自动跳转到另外一个你自己设定的页面？其实实现这个效果非常地简单，而且这个效果甚至不能称之为特效。你只要把如下代码加入你的网页中就可以了。

1，页面自动刷新：把如下代码加入<head>区域中<meta http-equiv="refresh" content="20">,其中20指每隔20秒刷新一次页面.

2，页面自动跳转：把如下代码加入<head>区域中<meta http-equiv="refresh" content="20;url=http://www.163.com">,其中20指隔20秒后跳转到http://www.163.com页面。

Q: 鼠标箭头变十字架代码(对一些特殊的网页有用) .
A: 你们自己试试效果就知道了.

<script language="JavaScript1.2">
<!--
if (document.all&&!window.print){
leftright.style.width=document.body.clientWidth-2
topdown.style.height=document.body.clientHeight-2
}
else if (document.layers){
document.leftright.clip.width=window.innerWidth
document.leftright.clip.height=1
document.topdown.clip.width=1
document.topdown.clip.height=window.innerHeight
}
function followmouse1(){
//move cross engine for IE 4+
leftright.style.pixelTop=document.body.scrollTop+event.clientY+1
topdown.style.pixelTop=document.body.scrollTop
if (event.clientX<document.body.clientWidth-2)
topdown.style.pixelLeft=document.body.scrollLeft+event.clientX+1
else
topdown.style.pixelLeft=document.body.clientWidth-2
}
function followmouse2(e){
//move cross engine for NS 4+
document.leftright.top=e.y+1
document.topdown.top=pageYOffset
document.topdown.left=e.x+1
}
if (document.all)
document.onmousemove=followmouse1
else if (document.layers){
window.captureEvents(Event.MOUSEMOVE)
window.onmousemove=followmouse2
}
function regenerate(){
window.location.reload()
}
function regenerate2(){
setTimeout("window.onresize=regenerate",400)
}
if ((document.all&&!window.print)||document.layers)
//if the user is using IE 4 or NS 4, both NOT IE 5+
window.onload=regenerate2
//-->
</script>
<style>
<!--
#leftright, #topdown{
position:absolute;
left:0;
top:0;
width:1px;
height:1px;
layer-background-color:#B0D0F8;
background-color:#00eeff;
z-index:100;
font-size:1px;
}
-->
</style>

【?上】然後切?Q到您的??，按『Ctrl+V』???????的程式??在</head>之前。


<div id="leftright" style="width:expression(document.body.clientWidth-2)">
</div>
<div id="topdown" style="height:expression(document.body.clientHeight-2)">
</div>

【?上】然後切?Q到您的??，按『Ctrl+V』???????的程式??在<body>之後任何位置。

【修改程式?】
若想改改?的?色，那就改background-color:#00eeff;?部份，後面的?色?就行了。
