前端JS对后台传递的timestamp的转换

Date.prototype.format = function(format) {
            var o = {
                "M+" : this.getMonth() + 1,// month
                "d+" : this.getDate(),// day
                "h+" : this.getHours(),// hour
                "m+" : this.getMinutes(),// minute
                "s+" : this.getSeconds(),// second
                "q+" : Math.floor((this.getMonth() + 3) / 3),// quarter
                "S" : this.getMilliseconds()
            // millisecond
            };
            if (/(y+)/.test(format) || /(Y+)/.test(format)) {
                format = format.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
            }
            for ( var k in o) {
                if (new RegExp("(" + k + ")").test(format)) {
                    format = format.replace(RegExp.$1, RegExp.$1.length == 1 ? o[k] : ("00" + o[k]).substr(("" + o[k]).length));
                }
            }
            return format;
        };

(new Date(parseFloat(value.time))).format("yyyy-MM-dd hh:mm:ss");
