javascript特效
http://www.codesky.net/article/doc/200508/200508115422220.htm
1、时钟显示任意指定位置
脚本说明：
第一步:把如下代码加入<body>区域中:
<span id=liveclock style=position:absolute;left:250px;top:122px;; width: 109px; height: 15px>
</span> （这里可以调整时钟的方位。调用脚本时去掉括号中内容）
<SCRIPT language=javascript>
<!--
function show5(){if(!document.layers&&!document.all)
return
var Digital=new Date()
var hours=Digital.getHours()
var minutes=Digital.getMinutes()
var seconds=Digital.getSeconds()
var dn="AM"
if(hours>12){dn="PM"
hours=hours-12
}if(hours==0)
hours=12
if(minutes<=9)
minutes="0"+minutes
if(seconds<=9)
seconds="0"+seconds
//change font size here to your desire
myclock="<font size='5' face='Arial'><b><font size='1'>Current Time:</font></br>"+hours+":"+minutes+":"
+seconds+" "+dn+"</b></font>"
if(document.layers){document.layers.liveclock.document.write(myclock)
document.layers.liveclock.document.close()
}else if(document.all)
liveclock.innerHTML=myclock
setTimeout("show5()",1000)
}
//>
</SCRIPT>
第二步:把<body>中的内容改为
<body bgcolor="#ffffff" ONLOAD=show5()>
2、纯javascript时钟
脚本说明：
第一步:把如下代码加入<head>区域中:
<SCRIPT language=javascript>
<!--
pX=400;pY=200
obs = new Array(13)
function ob () {
for (i=0; i<13; i++) {
if (document.all) obs[i]=new Array (eval('ob'+i).style,-100,-100)
else obs[i] = new Array (eval('document.ob'+i),-100,-100)
}
}
function cl(a,b,c){
if (document.all) {
if (a!=0) b+=-1
eval('c'+a+'.style.pixelTop='+(pY+(c)))
eval('c'+a+'.style.pixelLeft='+(pX+(b)))
}
else{
if (a!=0) b+=10
eval('document.c'+a+'.top='+(pY+(c)))
eval('document.c'+a+'.left='+(pX+(b)))
}
if (document.all) c0.style.pixelLeft=26
}
function runClock() {
for (i=0; i<13; i++) {
obs[i][0].left=obs[i][1]+pX
obs[i][0].top=obs[i][2]+pY
}
}
var lastsec
function timer() {
time = new Date ()
sec = time.getSeconds()
if (sec!=lastsec) {
lastsec = sec
sec=Math.PI*sec/30
min=Math.PI*time.getMinutes()/30
hr =Math.PI*((time.getHours()*60)+time.getMinutes())/360
for (i=1;i<6;i++) {
obs[i][1] = Math.sin(sec) * (44 - (i-1)*11)-16;
if (document.layers)obs[i][1]+=10;
obs[i][2] = -Math.cos(sec) * (44 - (i-1)*11)-27;
}
for (i=6;i<10;i++) {
obs[i][1] = Math.sin(min) * (40 - (i-6)*10)-16;
if (document.layers)obs[i][1]+=10;
obs[i][2] = -Math.cos(min) * (40 - (i-6)*10)-27;
}
for (i=10;i<13;i++) {
obs[i][1] = Math.sin(hr) * (37 - (i-10)*11)-16;
if (document.layers)obs[i][1]+=10;
obs[i][2] = -Math.cos(hr) * (37 - (i-10)*11)-27;
}
}
}
function setNum(){
cl (0,-67,-65);
cl (1,10,-51);
cl (2,28,-33);
cl (3,35,-8);
cl (4,28,17);
cl (5,10,35);
cl (6,-15,42);
cl (7,-40,35);
cl (8,-58,17);
cl (9,-65,-8);
cl (10,-58,-33);
cl (11,-40,-51);
cl (12,-16,-56);
}
//-->
</SCRIPT>
第二步:把<body>中加入如下代码：
<div id="c0" style="position:absolute;right:6;top:6; z-index:2;">
</div>
<div id="c1" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>1</b></div>

<div id="c7" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>7</b></div>
<div id="c8" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>8</b></div>
<div id="c9" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>9</b></div>

<div id="c12" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>12</b></div>
<div id="ob0" style="position:absolute;left:-20;top:-20;z-index:1"> </div>
<div id="ob1" style="position:absolute;left:-20;top:-20;z-index:8"> <font size="+3" color="#0000FF"><b>.</b></font></div>

<div id="ob5" style="position:absolute;left:-20;top:-20;z-index:8"> <font size="+3" color="#0000FF"><b>.</b></font></div>
<div id="ob6" style="position:absolute;left:-20;top:-20;z-index:7"> <font size="+3" color="#00FFFF"><b>.</b></font></div>
<div id="ob7" style="position:absolute;left:-20;top:-20;z-index:7"> <font size="+3" color="#00FFFF"><b>.</b></font></div>
<div id="ob8" style="position:absolute;left:-20;top:-20;z-index:7"> <font size="+3" color="#00FFFF"><b>.</b></font></div>
<div id="ob9" style="position:absolute;left:-20;top:-20;z-index:7"> <font size="+3" color="#00FFFF"><b>.</b></font></div>
<div id="ob10" style="position:absolute;left:-20;top:-20;z-index:6"> <font size="+3" color="#F30000"><b>.</b></font></div>
<div id="ob11" style="position:absolute;left:-20;top:-20;z-index:6"> <font size="+3" color="#F30000"><b>.</b></font></div>
<div id="ob12" style="position:absolute;left:-20;top:-20;z-index:6"> <font size="+3" color="#F30000"><b>.</b></font></div>
第三步：把<body>中内容改为：
<body bgcolor="#ffffff" onLoad="ob(),setNum(),setInterval('timer()',100);setInterval('runClock()',100)">
3、时钟显示在背景上
脚本说明：
第一步:把如下代码加入<head>区域中:
<script language=javaScript>
<!--//
function clockon() {
thistime= new Date()
var hours=thistime.getHours()
var minutes=thistime.getMinutes()
var seconds=thistime.getSeconds()
if (eval(hours) <10) {hours="0"+hours}
if (eval(minutes) < 10) {minutes="0"+minutes}
if (seconds < 10) {seconds="0"+seconds}
thistime = hours+":"+minutes+":"+seconds
if(document.all) {
bgclocknoshade.innerHTML=thistime
bgclockshade.innerHTML=thistime
}
if(document.layers) {
document.bgclockshade.document.write('<div id="bgclockshade" style="position:absolute;visibility:visible;font-family:Verdana;color:FFAAAAA;font-size:120px;top:10px;left:152px">'+thistime+'</div>')
document.bgclocknoshade.document.write('<div id="bgclocknoshade" style="position:absolute;visibility:visible;font-family:Verdana;color:DDDDDD;font-size:120px;top:10px;left:150px">'+thistime+'</div>')
document.close()
}
var timer=setTimeout("clockon()",200)
}
//-->
</script>
第二步:把<body>中加入如下代码：
<div id="bgclockshade" style="position:absolute;visibility:visible;font-family:Arial;color:FF8888;font-size:120px;top:102px;left:152px"></div>
<div id="bgclocknoshade" style="position:absolute;visibility:visible;font-family:Arial;color:DDDDDD;font-size:120px;top:100px;left:150px"></div>
<div id="mainbody" style="position:absolute; visibility:visible">
</div>
第三步：把<body>中内容改为：
<body bgcolor="#ffffff" onLoad="clockon()">
4、文字跳动显示

第一步:把如下代码加入<head>区域中

</SCRIPT>
第二步:把如下代码加入<body>区域中(也就是在页面中调用脚本)
<p dynamicanimation8="dropWord"
style="position: relative !important; left: 10000 !important" align="center"><font size="3" color="#ee00FF">很 好 玩 吧 ! 有 没 有 吓 一 跳 ?<font size="7"><b><font face="Arial, Helvetica, sans-serif" color="#FF0000">YES!
</font></b></font></font></p>
第三步:把<body>改为
<body bgcolor="#ffffff" onload="dynAnimation8()">
5、页面自动刷新
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.hrw.cn">,其中20指隔20秒后跳转到http://www.hrw.cn页面。
6、汉字数字转数字
<script language="JavaScript">
<!--
function word2number(w)
{
var e = "零一二三四五六七八九";
var ew = ["十","百","千"];
var ej = ["万","亿"];
var rss = "^(["+e+ew.join("")+"]+"+ej[1]+")?(["+e+ew.join("")+"]+"+ej[0]+")?(["+e+ew.join("")+"]+)?$";
var arr = new RegExp(rss).exec(w);
function foh(str)
{
var a=0;
if(str.indexOf(ew[0])==0)
a=10;
str=str.replace(new RegExp(e.charAt(0),"g"),"");
if(new RegExp("(["+e+"])$").test(str))
a+=e.indexOf(RegExp.$1);
if(new RegExp("(["+e+"])"+ew[0]).test(str))
a+=e.indexOf(RegExp.$1)*10;
if(new RegExp("(["+e+"])"+ew[1]).test(str))
a+=e.indexOf(RegExp.$1)*100;
if(new RegExp("(["+e+"])"+ew[2]).test(str))
a+=e.indexOf(RegExp.$1)*1000;
return a;
}
return foh(arr[1])*100000000+foh(arr[2])*10000+foh(arr[3]);
}
alert(word2number("六"));
alert(word2number("十五"));
alert(word2number("五百零二"));
alert(word2number("四千五百"));
alert(word2number("七十亿零八百五十万四千五百零二"));
//-->
</script>
7、数字转汉字
function Chinese(num){ //将阿拉伯数字翻译成中文的大写数字
if(!/^\d*(\.\d*)?$/.test(num)){alert("Number is wrong!"); return "Number is wrong!";}
var AA = new Array("零","一","二","三","四","五","六","七","八","九");
var BB = new Array("","十","百","千","万","亿","点","");
var a = (""+ num).replace(/(^0*)/g, "").split("."), k = 0, re = "";
for(var i=a[0].length-1; i>=0; i--){
switch(k){
case 0 : re = BB[7] + re; break;
case 4 : if(!new RegExp("0{4}\\d{"+ (a[0].length-i-1) +"}$").test(a[0]))
re = BB[4] + re; break;
case 8 : re = BB[5] + re; BB[7] = BB[5]; k = 0; break;
}
if(k%4 == 2 && a[0].charAt(i+2) != 0 && a[0].charAt(i+1) == 0) re = AA[0] + re;
if(a[0].charAt(i) != 0) re = AA[a[0].charAt(i)] + BB[k%4] + re; k++;
}
if(a.length>1) //加上小数部分(如果有小数部分)
{
re += BB[6];
for(var i=0; i<a[1].length; i++) re += AA[a[1].charAt(i)];
}
//return re;
document.all.text2.value=re;
}
8、防拷贝页面
<body oncontextmenu="return false" onselectstart="return false"
ondragstart="return false">
再加上<noscript> <iframe src="*.htm"></iframe> </noscript>
防止别人另存
