function formate(date, f)
{
var o = {
"M+": date.getMonth() + 1,
"d+": date.getDate(),
"h+": date.getHours(),
"m+": date.getMinutes(),
"s+": date.getSeconds(),
"q+": Math.floor((date.getMonth() + 3) / 3),
"S": date.getMilliseconds()
};
if (/(y+)/.test(f))
f = f.replace(RegExp.$1, (date.getFullYear() + "").substr(4 - RegExp.$1.length));
for (var k in o)
if (new RegExp("(" + k + ")").test(f))
f = f.replace(RegExp.$1, RegExp.$1.length == 1 ? o[k] : ("00" + o[k]).substr(("" + o[k]).length));
return f;
}

alert(formate(new Date(),'yyyy-MM-dd'));

我会这样写：

function formatDate(date, format) {

    if (!date) return;

    if (!format) format = "yyyy-MM-dd";

    switch(typeof date) {

        case "string":

            date = new Date(date.replace(/-/, "/"));

            break;

        case "number":

            date = new Date(date);

            break;

    } 

    if (!date instanceof Date) return;

    var dict = {

        "yyyy": date.getFullYear(),

        "M": date.getMonth() + 1,

        "d": date.getDate(),

        "H": date.getHours(),

        "m": date.getMinutes(),

        "s": date.getSeconds(),

        "MM": ("" + (date.getMonth() + 101)).substr(1),

        "HH": ("" + (date.getHours() + 100)).substr(1),

        "mm": ("" + (date.getMinutes() + 100)).substr(1),

        "ss": ("" + (date.getSeconds() + 100)).substr(1)

    };    

    return format.replace(/(yyyy|MM?|dd?|HH?|ss?|mm?)/g, function() {

        return dict[arguments[0]];

    });
