html5已經出來好長時間了，但仍然有不多小伙伴們不太懂，下面小編就來用html5實現一個簡單的鐘錶外觀
<html lang="en-US">
<style>
#myCanvas{border:3px solid blue;}
</style>
<head>
<script type="text/javascript">
window.onload = function()
{
var mycanvas = document.getElementById("myCanvas");
var context = mycanvas.getContext("2d");
context.lineWidth = 2;
context.strokeStyle = "blue";
context.fillStyle = "blue";
context.arc(250,200,5,0,Math.PI*2,true);
context.fill();
context.beginPath();
context.arc(250,200,150,0,Math.PI*2,true);
context.stroke();
context.translate(250,200);
context.rotate(-Math.PI/2);
context.save();
for(var i=0;i<60;i++)
{
if(i % 5 == 0)
{
context.fillRect(130,0,20,5);
context.fillText((i/5 == 0?12:i/5),120,5);
}
else
{
context.fillRect(140,0,10,2)
}
context.rotate(Math.PI/30); //360°每6度旋转一次
}
context.fillRect(0,-2,90,3);
context.stroke();
}
</script>
</head>
<body>
<canvas id=myCanvas width=500px height=400px></canvas>
</body>
</html>
