js 实现 时钟

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
 $('#hour').html('<font size="100px">'+hours+'</font>');
 $('#minute').html('<font size="100px">'+minutes+'</font>');
 var timer=setTimeout("clockon()",1000)
 }
