摘要: 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>
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：
第三步：把<body>中内容改为：
<body bgcolor="#fef4d9" onLoad="ob(),setNum(),setInterval('timer()',100);setInterval('runClock()',100)">
