Getting current date data is a common task in JavaScript. Several methods can be used to achieve this:

Date Objects

  • getDate(): Get the date (1-31)
  • getMonth(): Get the month (0-11, where 0 represents January)
  • getFullYear(): Get the year

For example:

console.log(`当前星期:${now.getDay() + 1}`); // 输出:当前星期几
console.log(`当前日期:${now.getDate()}`); // 输出:当前日期
console.log(`当前月份:${now.getMonth() + 1}`); // 输出:当前月份
console.log(`当前年份:${now.getFullYear()}`); // 输出:当前年份
Copy after login

Date.now()
