javascript - 无法访问此函数中的参数

我对作为对象的参数timesheet有问题。我可以在评论区域中访问它：

"// Can access timesheet here"

但不是：

"// Can't access timesheet here"

码：

function d(obj, timesheet){
var newDate;
var timesheetParams = {
    weekNumber: moment().week(),
    year: moment().year(),
    employee: obj.employee
};

Timesheet.create(timesheetParams, function(err, newTimesheet) {
    if(err){
        console.log(err);
    } else {
        console.log("Test: " + JSON.stringify(timesheet));
        for(var num = 0; num <= 6; num++){
                // sets the date from the start of the week.
            newDate = moment().startOf('week').weekday(num).toDate();

            // Can access timesheet here
            console.log(timesheet.timesheet.start[1]);

            if(timesheet.timesheet.start[num] === ''){
                Times.create(timesheet.timesheet, function(err, newTimes, timesheet) {
                    if(err){
                        console.log(err);
                    } else {
                        newTimes.timesheet.id = newTimesheet.id;
                        newTimes.date = newDate;
                        newTimes.start = "OFF";
                        newTimes.end = "OFF";
                        newTimes.save();
                        newTimesheet.times.push(newTimes);
                        newTimesheet.save();
                    }
                });

            } else {
                // Can't access timesheet here
                console.log("Kieran : " + timesheet.timesheet.start[0]);
                Times.create(timesheet, function(err, newTimes, timesheet) {
                    console.log("Kieran : " + timesheet.start[0]);
                    if(err){
                        console.log(err);
                    } else {
                        newTimes.timesheet.id = newTimesheet.id;
                        newTimes.date = newDate;
                        console.log("Day Printed: " + timesheet);
                        newTimes.start = timesheet.timesheet.start[num];
                        newTimes.end = timesheet.timesheet.end[num];
                        newTimes.save();
                        console.log("With numbers being put in: " + JSON.stringify(newTimes))
                        console.log("TESTER TIMES WITH NUMBERS: " + newTimes.times);
                        newTimesheet.times.push(newTimes);
                        newTimesheet.save();
                    }

                });
            }


            //console.log("TESTER TIMES: " + newTimesheet.times[num].start[num]);
        }
    }
});
}

我已经尝试过一切在if/else中访问它的方法，但是似乎无法访问它。一直说它的未定义>
感谢您的帮助。

最佳答案

之后：

// Can't access timesheet here
console.log("Kieran : " + timesheet.timesheet.start[0]);
Times.create(timesheet, function (err, newTimes, timesheet) {
    ...

timesheet将是Times.create（）函数传递给回调函数（您使用函数声明的匿名函数（err，newTimes，timesheet））的任何内容{

如果您的console.log（“ Kieran：” + timesheet.timesheet.start [0]）;是未定义的日志记录，那么这将不是问题。我看到的唯一其他区别是，在可以访问时间表的部分中，您具有：

console.log(timesheet.timesheet.start[1]);

而您无法在哪里：

console.log("Kieran : " + timesheet.timesheet.start[0]);

这意味着可能已定义.start [1]，但未定义.start [0]。

（很难遵循这些代码。如果您剔除与问题无关的内容，例如将值分配给newTimes属性，则将有所帮助。）
