将时间转换为 Date 类型的 Nest.js

convert time to Date type nest js

问题

在上面的代码中,data.Intime 是一个表示时间的字符串(例如:"00:39:41"),而 attendance.date 是一个 Date 类型的变量。您可以使用以下方法将 data.Intime 转换为 Date 类型:

// 将 data.Intime 字符串解析为 Date 对象
attendance.date = new Date(`1970-01-01T${data.Intime}Z`);

这里我们将data.Intime字符串与日期字符串("1970-01-01T")组合,然后将其传递给 Date 构造函数来创建一个包含日期和时间信息的 Date 对象。最终的 Date 对象将包含正确的日期和时间信息,可以用于赋值给 attendance.date 变量。

英文:
 @Cron('23 16 * * *')
  async transferData() {
    try {
      // Retrieve data from the AttendanceBulk table
      const attendanceBulkData = await this.AttendanceBulkModel.findAll();
  
      for (const data of attendanceBulkData) {
        const attendance = new Attendance();
        
        // Find the corresponding AttendanceAndBulk entry based on data.UserId
        const attendanceAndBulk = await AttendanceAndBulk.findOne({ where: { UserId: data.UserId } });
  
        if (attendanceAndBulk) {
          attendance.employeeId = attendanceAndBulk.employeeId;
          attendance.shiftType = data.Intime ? ShiftType.In : ShiftType.Out;
          attendance.time = new Date(`${data.Intime}`);;
          attendance.date = data.Date;
          attendance.outTime= data.Date;

          console.log(data.Intime)
          await attendance.save();
        }
      }
  
      this.logger.log('Data transfer completed successfully.');
    } catch (error) {
      this.logger.error('Data transfer failed:', error);
    }
  }


In above code I data.Intime is comming like 00:39:41 this. but attendance.date variable is Date type. how can I convert time varibale(00:39:41) to Date type in nest js?

只返回翻译好的部分:

你只接收小时/分钟/秒钟

这不足以创建一个日期

一个可能有效的解决方案是创建当天的日期,然后将接收到的时间设置在这个日期上

const [hours, minutes, seconds] = date.InTime.split(':');
const timestamp = (new Date()).setHours(hours, minutes, seconds);
const date = new Date(timestamp);

这是关于Date对象的文档链接,我们从中调用setHours方法
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/setHours

如果您计划大量使用日期,我还建议查看dayjs,这是一个非常方便的JavaScript日期操作库
https://day.js.org/

英文:

You are only receiving hour/minutes/secondes

This is not sufficient to create a date

A solution that might work would be to create the date of the day, and then set the received time on this date

const [hours, minutes, seconds] = date.InTime.split(':');
const timestamp = (new Date()).setHours(hours, minutes, seconds);
const date = new Date(timestamp);

Here is the link of the documentation for the Date object, from wich we call the setHours methods
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/setHours

If you plan on working with date a lot, i would also advise to checkout dayjs, a very convenient library for date manipulation in javascript
