JavaScript日期排序

        //日期排序
        function sortDownDate(a, b) {
            return Date.parse(a.received) - Date.parse(b.received);
        }

        function sortUpDate(a, b) {
            return Date.parse(b.received) - Date.parse(a.received);
        }


        var arr=[

                age: "22"
            },
            {
                sender: "elon",
                received: "2017-04-18 13:23:21",
                age: "22"
            },
            {
                sender: "lson",
                received: "2017-06-18 13:23:21",
                age: "22"
            },
            {
                sender: "eon",
                received: "2017-08-18 13:23:21",
                age: "22"
            },
        ];

        //console.log(arr.sort(sortDownDate));//正序
        //console.log(arr.sort(sortUpDate));//反序

　　结果如下：

　　左为正序

(arr.sort(sortDownDate))，右为反序(arr.sort(sortUpDate))
