用JavaScript获取日期

var d = new Date();
var date = [ d.getDate(), d.getMonth() + 1, d.getFullYear() ];
var time = [
    (d.getHours() > 12) ? d.getHours() - 12 : (d.getHours() == 0) ? 12 : d.getHours(),
    d.getMinutes(),
    d.getSeconds()
];

"".concat(date.join("/"), " ", time.join(":"), " ", (d.getHours() > 11) ? "PM" : "AM");

Date

Date.prototype.getFormatted = function() {
    var date = [ this.getDate(), this.getMonth() + 1, this.getFullYear() ];
    var time = [
        (this.getHours() > 12) ? this.getHours() - 12 : (this.getHours() == 0) ? 12 : this.getHours(),
        this.getMinutes(),
        this.getSeconds()
    ];

    return "".concat(date.join("/"), " ", time.join(":"), " ", (this.getHours() > 11) ? "PM" : "AM");
};

var d = new Date();
d.getFormatted();

var currentTime = new Date();
var day = currentTime.getDate();
