Date.now（）如何在javascript中工作？

Question

我正在尝试创建一个可以轻松与他人联系的时间值。

var created = Date.now() * 1000

var day_ago = Date.now() * 1000 - 24*60*60

if(created > day_ago){console.log('it was created in the last day')}

这似乎无法正常工作，任何人都知道我在做什么错

Answer 1

Date.now（）将返回毫秒数，除以1000会将其转换为秒数。

var created = Date.now() / 1000

var day_ago = Date.now()/ 1000 - 24*60*60

if(created > day_ago){console.log('it was created in the last day')}

Answer 2

您必须除以1000，而不是相乘

var created = Date.now() / 1000
var day_ago = Date.now() / 1000 - 24*60*60
if(created > day_ago){console.log('it was created in the last day')}
