用时间格式化方法把年月日星期分别取出来然后拼到一起。

项目中用的

Date.prototype.Format = function (fmt) {
    function setMonth(month) {
        var engMonth;
        switch (month) {
            case 0:
                engMonth = 'Jan';
                break;
            case 1:
                engMonth = 'Feb';
                break;
            case 2:
                engMonth = 'Mar';
                break;
            case 3:
                engMonth = 'Apr';
                break;
            case 4:
                engMonth = 'May';
                break;
            case 5:
                engMonth = 'Jun';
                break;
            case 6:
                engMonth = 'Jul';
                break;
            case 7:
                engMonth = 'Aug';
                break;
            case 8:
                engMonth = 'Sep';
                break;
            case 9:
                engMonth = 'Oct';
                break;
            case 10:
                engMonth = 'Nov';
                break;
            case 11:
                engMonth = 'Dec';
                break;
        }
        return engMonth
    }
    function setTimezone(x) {
        var timezone,sign;
        var a = x/-60;
        sign = a>0 ? '+' : '-';
        if (Math.abs(a) < 10) {
            a = '0' + a;
        }
        timezone = sign + a + ':00';
        return timezone;
    }
    function addZero(a) {
        var target;
        target = a < 10 ? '0'+ a : a;
        return target;
    }
    var o = {
        "M+": setMonth(this.getMonth()), //month
        "d+": addZero(this.getDate()), //day
        "h+": this.getHours(), //hour 
        "m+": addZero(this.getMinutes()), //minute
        "s+": addZero(this.getSeconds()), //seconds
        "q+": Math.floor((this.getMonth() + 3) / 3), //quarter
        "S": this.getMilliseconds(), //milliseconds
        "T": setTimezone(this.getTimezoneOffset())
    };
    if (/(y+)/.test(fmt)) fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
    for (var k in o)
        if (new RegExp("(" + k + ")").test(fmt)) fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));
    return fmt;
};

调用

new Date().Format('d-M-yyyy h:m:s T')
"15-Jun-2016 17:46:26 +08:00"

没有一个直接的方法，都是获取一个时间戳然后得到年月日之后进行字符串拼接
