JS+CSS3实现时钟
使用js和css3实现的时钟效果,支持firefox,chrom等标准浏览器。下载
效果如图:
javascript:
<script type="text/javascript" src="jquery-1.8.2.min.js"></script>
<script type="text/javascript">
$(function () {
function rotateHand() {
var myDate = new Date();
var s = myDate.getSeconds();
var m = myDate.getMinutes();
var h = myDate.getHours();
var timeNow = h + ":" + m + ":" + s;
var sRotate = s / 60 * 360;
var mRotate = m / 60 * 360 + 6 * s / 60;
var hRotate = (h>12?h-12:h) / 12 * 360 + 30 * m / 60;
$("#second_hand").attr('style', 'transform:rotate(' + sRotate + 'deg)');
$("#minute_hand").attr('style', 'transform:rotate(' + mRotate + 'deg)');
$("#hour_hand").attr('style', 'transform:rotate(' + hRotate + 'deg)');
$("#time_now").empty().append(timeNow);
}
setInterval(rotateHand,200);
})
</script>
css:
<style type="text/css">
