利用css3 transform属性刻画钟表的的刻度以及指针的角度,代码如下：
<head>
<meta charset="utf-8">
<title>title</title>
<style id="style">
html{height:100%;}
body {
width:100%;
height:100%;
margin:0;
display:-moz-box;
display:-webkit-box;
display:box;
-webkit-box-align: center;
-moz-box-align: center;
box-align:center;
-webkit-box-pack:center;
-moz-box-pack:center;
box-pack:center;
}
.clock {
width:200px;
height:200px;
border:4px solid black;
border-radius:50%;
position:relative;
}
.clock ul {
width:100%;
height:100%;
position:relative;
margin:0;
padding:0;
}
.clock ul li {
list-style: none;
position:absolute;
top:0;
left:99px;
width:2px;
height:5px;
background:gray;
transform-origin: center 100px;
}
.clock ul li:nth-of-type(5n+1) {
left:98px;
width:4px;
height:10px;
background:black;
}
.hour {
width:8px;
height:60px;
border-radius:4px;
position:absolute;
left:96px;
top:40px;
background-color:black;
transform-origin: center 60px;
box-shadow:0 0 10px rgba(0,0,0,0.8);
}
.min {
width:6px;
height:70px;
border-radius:3px;
position:absolute;
left:97px;
top:30px;
background-color:#2b2b2b;
transform-origin: center 70px;
box-shadow:0 0 10px rgba(0,0,0,0.6);
}
.sec {
width:4px;
height:80px;
border-radius:2px;
position:absolute;
left:98px;
top:20px;
background-color:red;
transform-origin: center 80px;
box-shadow:0 0 10px rgba(255,0,0,0.5);
}
.center {
width:16px;
height:16px;
box-shadow:0 2px 5px rgba(0,0,0,0.5);
border-radius:50%;
position:absolute;
left:92px;
top:92px;
background-image: radial-gradient(white,gray);
}
</style>
</head>
<body>
<p class="clock">
<ul id="tickbox">
</ul>
<p class="hour" id="hour"></p>
<p class="min" id="min"></p>
<p class="sec" id="sec"></p>
<p class="center"></p>
</p>
<script>
window.onload = function(){
var oul = document.getelementbyid("tickbox");
var ostyle = document.getelementbyid("style");
var listr = "";
var stylestr = "";
for(var i=0;i<60;i++){
stylestr += '.clock ul li:nth-of-type('+(i+1)+'){transform: rotate('+i*6+'deg);}';
listr += '<li></li>';
}
ostyle.innerhtml += stylestr;
oul.innerhtml = listr;
var ohour = document.getelementbyid("hour");
var omin = document.getelementbyid("min");
var osec = document.getelementbyid("sec");
function gettime(){
var timer = new date();
var sec = timer.getseconds();
var min = timer.getminutes();
var hour = timer.gethours();
var trans = sec*360/60;
var tranm = (min+sec/60)*360/60;
var tranh = (hour + min/60)*360/12;
osec.style.transform = 'rotate('+trans+'deg) translatez(-1px)';
omin.style.transform = 'rotate('+tranm+'deg) translatez(-1px)';
ohour.style.transform = 'rotate('+tranh+'deg) translatez(-1px)';
}
setinterval(gettime,1000);
gettime();
}
</script>
</body>
