Question

当前，我面临以下问题。在我的JavaScript代码中，我有一个函数，该函数应该计算从现在开始到给定时间戳记的星期数。问题在于，第一个值与另一个具有另一个名称的变量具有相同的值。代码：

let myAppointment = event.data.toTime;
            console.log(myAppointment);
            let currentDate = new Date(Date.now());
            let currentTime = (convertStringDateToDate(currentDate.getFullYear(), currentDate.getMonth(), currentDate.getDate(), 0,0,0,0)).getTime();
            let appointmentStartDate = new Date(myAppointment.getStart());
            console.log(appointmentStartDate);
            console.log(currentDate);
            let appointmentStartTime = (convertStringDateToDate(appointmentStartDate.getFullYear(), appointmentStartDate.getMonth(), appointmentStartDate.getDate(),0,0,0,0)).getTime();
            console.log('AppointmentStartTime : ' + appointmentStartTime);
            console.log('CurrentTime: ' + currentTime);
            let timeskip = appointmentStartTime - currentTime;
            console.log(timeskip + ' timeskip / 604800000 = ' + (timeskip / 604800000));
            skips = timeskip / 604800000;
            await displayCalendar(document.getElementById('wrapper'));
            console.log(skips);
            if(skips < 0){
                skips = Math.floor(skips);
                if(Math.abs(skips) != 1){
                    navigateBackward(skips);
                }

            }else{
                skips = Math.floor(skips);
                if(Math.abs(skips) != 1){
                    navigateForward(skips);
                }
            }
            cleanTable();
            displayAppointments();
});

//i think this function may be interesting too, but the error can't occur from here
function
convertStringDateToDate(year,month,day,hours,minutes,seconds,milliseconds){
    let date = new Date();
    date.setFullYear(year);
    date.setMonth(month);
    date.setDate(day);
    date.setHours(hours);
    date.setMinutes(minutes);
    date.setSeconds(seconds);
    date.setMilliseconds(milliseconds);
    return date;
}

let myAppointment = ...中的函数导致以下控制台输出

请注意，在您的特定示例中，Traceback (most recent call last): File "/Users/bliu4/.local/bin/sam", line 11, in <module> sys.exit(cli()) File "/Users/bliu4/anaconda3/lib/python3.6/site-packages/click/core.py", line 722, in __call__ return self.main(*args, **kwargs) File "/Users/bliu4/anaconda3/lib/python3.6/site-packages/click/core.py", line 676, in main _verify_python3_env() File "/Users/bliu4/anaconda3/lib/python3.6/site-packages/click/_unicodefun.py", line 118, in _verify_python3_env 'for mitigation steps.' + extra) RuntimeError: Click will abort further execution because Python 3 was configured to use ASCII as encoding for the environment. Consult http://click.pocoo.org/python3/for mitigation steps.和currentDate共享相同的年份，月份和日期。调用appointmentStartDate时，应将let currentTime = (convertStringDateToDate(currentDate.getFullYear(), currentDate.getMonth(), currentDate.getDate(), 0,0,0,0)).getTime();和0,0,0,0的正确值替换为currentTime。

要使编码风格保持一致，可以使用appointStartTime，date.getHours()，date.getMinutes()和date.getSeconds()替换这四个零。

此外，如果您想缩短代码，则可以摆脱date.getMilliseconds()，而只需在convertStringDateToDate()和getTime()上调用currentDate。

appointStartDate

Answer 2

问题出在这里：

 let appointmentStartTime = (convertStringDateToDate(appointmentStartDate.getFullYear(), appointmentStartDate.getMonth(), appointmentStartDate.getDate(),0,0,0,0)).getTime();

您将小时，分钟，秒都设置为零-有效地将开始日期更改为与今天的日期相同的值。
