无法读取null javascript的属性“ split”

Question

我正在尝试设置cron，但它告诉我Google chrome控制台中的拆分存在错误，我花了一周的时间来解决该错误

这将jquery 2.1.3与mongo数据库一起使用

function doWork(){
    makeCall('data/getSchedule.php','',function(err,res){
        var lastMovedDay= res.lastDay;
        var lastExecDay= res.lastExec;
        if($("input[name=tipo]:checked").val()=="especifico"){
            var _firstExec= $('#1Ejecucion').val();
            var _dayExec= $('#diaEjecucion').val();
            var arrayDate= _firstExec.split('-');
            var _hour= $("#horaEspecifica").val();
            var _begin= $("#diaDesde").val();
            var _end= $("#diaHasta").val();
            var date= new Date(arrayDate[0], (arrayDate[1]-1), arrayDate[2]);
            var arrayLastExec=lastMovedDay.split('-');
            var lastDate= new Date(arrayLastExec[0], arrayLastExec[1]-1, arrayLastExec[2]);
            lastDate.setDate(lastDate.getDate() + 7);
            if(_dayExec==days[date.getDay()]){
                if(lastDate<=date){                 
                    params = {
                        dayExec:_dayExec,
                        hour:_hour,
                        firstExec:_firstExec,
                        begin:_begin,
                        end:_end
                    }
                    makeCall('data/guardarCalendarizacion.php',params,function(err,res){
                        alert("Calendarización Actualizada");
                    });
                }
                else{
                    alert("La fecha de primera ejecución debe ser mayor al  "+ lastDate.toISOString().slice(0, 10));
                }
            }
            else{
                alert("El día de primera ejecución debe ser un "+ $('#diaEjecucion').val());
            }
        }
        else{
            var _hour= $("#horaRecurrente").val();
            var _rec=parseInt($("#diasRec").val());
            var today= new Date();
            today.setHours(0,0,0,0);
            var arrayLastDay=lastMovedDay.split('-');           
            var lastDate= new Date(arrayLastDay[0], arrayLastDay[1]-1, arrayLastDay[2]);
            lastDate.setDate(lastDate.getDate()+1);
            var limitMin= new Date(today);          
            limitMin.setDate(limitMin.getDate() - _rec);            
            var limit= new Date(today);
            limit.setDate(limit.getDate() -1);
            var next= new Date(today);
            next.setDate(next.getDate() + _rec-1);
            console.log(_rec+ " "+limitMin + " "+ lastDate);
            var save= true;
            if(limitMin>lastDate){
                console.log("mayor");
                limitMin.setDate(limitMin.getDate()-1);
                var r = confirm("Los tiempos del rango "+ lastDate.toISOString().slice(0, 10)+" - "+limitMin.toISOString().slice(0, 10)+ " no se va trasladar. \n ¿Desea Guardar la calendarización?");
                if (!r) {
                    save=false;
                }           
            }
            if(save){
                params = {
                    hour:_hour,
                    rec:_rec
                }
                makeCall('data/guardarCalendarizacion.php',params,function(err,res){
                    alert("Calendarización Actualizada");
                });
            }
        }
    });
}

错误在以下几行中：** var array Date = _first Exec.split（'-'）; ** ** var arrayLastExec = lastMovedDay.split（'-'）; ** ** var arrayLastDay = lastMovedDay.split（'-'）; **

数据来自文件GetSchudele.php，它正在尝试连接到集合，但没有带来任何东西，当我尝试保存它并没有保存我时，错误仍然存​​在于分割中
