后端时间转js时间，主要用于取倒计时

直接贴代码：

var expiretime = "2017-06-16 10:04:00";//后端是传字符串的格式var timeStrSplitArr = expiretime.split("T");
        var yearMonthDate = timeStrSplitArr[0].split("-");
        var hourMinuteSecond_miniSecond = timeStrSplitArr[1].split(".");
        var hourMinuteSecond = hourMinuteSecond_miniSecond[0];
        var year = parseInt(yearMonthDate[0]);
        var month = parseInt(yearMonthDate[1]) - 1;
        var date = parseInt(yearMonthDate[2]);
        hourMinuteSecond = hourMinuteSecond.split(":");
        var hour = parseInt(hourMinuteSecond[0]);
        var minute = parseInt(hourMinuteSecond[1]);
        var second = parseInt(hourMinuteSecond[2]);
        var miniSecond = parseInt(hourMinuteSecond_miniSecond[1]);

        var endDate = new Date(year, month, date, hour, minute, second, miniSecond);
