JS函数库

获取当前日期：形如xxxx年xx月xx日

function getDate() {
    var date = new Date();
    var month = date.getMonth() + 1;
    var strDate = date.getDate();
    var currentdate = date.getFullYear() + '年' + month + '月' + strDate + '日';
    document.getElementById("CurrentDate").innerHTML += currentdate;
}

日期格式化函数:形如2016-0814

function dateFormat() {
    var myDate = new Date();
    var today = "";
    today = myDate.getFullYear() + (((myDate.getMonth()) < 10) ? ("-0" + myDate.getMonth()) : (myDate.getMonth())) + (((myDate.getDate()) < 10) ? ("-0" + myDate.getDate()) : (myDate.getDate()));
    document.write(today);
}

时钟函数:形如2:50:56

function clock() {
    var today = new Date();
    var h = today.getHours();
    var m = today.getMinutes();
    var s = today.getSeconds();
    m = checkTime(m);
    s = checkTime(s);
    document.getElementById("clock").innerHTML = h + ":" + m + ":" + s;
    t = setTimeout(function() {
        clock();
    }, 500);
}

function checkTime(i) {
    if (i < 10) {
        i = "0" + i;
    }
    return i;
}
