我正在尝试从当前日期和时间到最后一个小时,上个月和昨天,我使用Date()对象来获取当前日期和时间:
function fetchCurrentDateTime() {
var currentDateobj = new Date()
var Day = currentDateobj.getDate()
var Hour = currentDateobj.getHours()
var Month = 1+(currentDateobj.getMonth())
var Year = currentDateobj.getFullYear()
console.log('Today is:', Day+'-'+Month+'-'+Year);
console.log('yesterday was:', Day-1+'-'+Month+'-'+Year);
console.log('Its', Hour, 'hrs');
console.log('It was', Hour-1, 'an Hour back.');
console.log('This is:', Month, 'Month');
console.log('It was', Month-1, 'Month, a month ago.');
console.log('It is', Year);
}
我想要的功能不仅可以返回日期或时间,还可以返回完整的日期时间,如:
Today: '2013-05-21 10:06:22'
Yesterday: '2013-05-20 10:06:22'
Current Hour: '2013-05-21 10:06:22'
Last Hour: '2013-05-21 09:06:22'
Current Month: '2013-05-21 10:06:22'
Last Month: '2013-04-21 10:06:22'
我还想问一下,如果小时为00:00:00
,那么最后一小时的结果是什么呢?与月份和日期相同。
答案 0 :(得分:11)
var today = new Date();
var yesterday = new Date(today.getTime() - (1000*60*60*24));
var hourago = new Date(today.getTime() - (1000*60*60));
console.log(today);
console.log(yesterday);
console.log(hourago);
getTime()
返回 Date 对象的时间戳。然后,您可以减去适当的毫秒数,并从该数字中创建一个新对象。如果需要,您现在可以按照您希望的方式格式化日期。
