在JavaScript中， 获取当前日期和时候有许多种方法，

1. 获取当前日期和时候

javascript const date = new Date; console.log; // 输出完整的日期和时候对象

2. 获取年、月、日

javascript const year = date.getFullYear; const month = date.getMonth + 1; // getMonth返回的月份是从0开头的，所以需要加1 const day = date.getDate;

3. 获取星期几

javascript const weekDay = ; const dayOfWeek = weekDay;

4. 获取当前时候戳

javascript const timestamp = date.getTime;

5. 格式化日期

javascript const options = { year: 'numeric', month: 'long', day: 'numeric', hour: 'numeric', minute: 'numeric', second: 'numeric', timeZone: 'Asia/Shanghai' }; const formattedDate = date.toLocaleDateString;

6. 获取当天、昨天、明天

javascript function getYesterday { const yesterday = new Date; yesterday.setDate - 1); return yesterday; }

function getToday { return new Date; }

function getTomorrow { const tomorrow = new Date; tomorrow.setDate + 1); return tomorrow; }

7. 计算两个日期之间的天数差

javascript function dateDiff { const firstDate = new Date; const secondDate = new Date; const diffTime = Math.abs; const diffDays = Math.ceil); return diffDays; }

8. 用Date.parse转换字符串

javascript const dateString = '2024-05-23'; const date = new Date;
