一个简易的时间显示器

 function clock() {
     var today = new Date();
     var days = today.getDay();
     var day = today.getDate();
     var month = today.getMonth();
     month += 1;
     var year = today.getYear();
     year += 1900;
     var hour = today.getHours();
     var minute = today.getMinutes();
     minute = ms(minute);
     var second = today.getSeconds();
     second = ms(second);
     document.getElementById("time").innerHTML = year + "年 " + month + "月 " + day + "日 星期" + days + " " + hour + ":" + minute + ":" + second;
     setTimeout("clock()", 1000);
 }

 function ms(x) {
     if (x < 10) {
         x = "0" + x;
     }
     return x;
 }
