怎么樣改可以讓執行代碼在timeteam[n] <= endtime 的條件下執行循環？        //時間        var startdate = new Date("2016-10-24 20:00:00");        var starttime = startdate.getTime();        var enddate = new Date("2016-10-26 20:00:00");        var endtime = enddate.getTime();        var timeteam = new Array();        var s = 0;        var sri = "";        var m;        var n = 0        do{            timeteam[n] = starttime + 1800000*s;            s++;            var myDate = new Date(timeteam[n]);            var m = myDate.getFullYear() + "/" + myDate.getMonth() + "/" + myDate.getDate() + " " + myDate.getHours() + ":" + myDate.getMinutes() + ",";            sri = sri + m;            n++;        }        while(n < 20)        var ss = sri.split(",");        ss.pop();        console.log(ss);
