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;
}
