如何在反应原生和/或 javascript 中将欧洲日期格式转换为日期 Object？

Question

Given a date such as November 23, 2021 in this European format: 23/11/2021. I try converting it to a date object like this:

const dateString =  '23/11/2021'
const dateObj = new Date(dateString)

However, this is giving me an error saying this is an invalid date. I don't want to just convert it to the US date format, since I am trying to see if I can sort the dates given the European format. Anyone know how I can convert this to a date object given the european date format?

Answer 1

If the format is always dd.MM.yyyy it can be done by slicing the date string to get the year, month and day required to create the Date object.

 const date = '23/11/2021' let d = date.slice(0,2), m = date.slice(3,5), y = date.slice(6,10); const dateObj = new Date(y, m, d) console.log(dateObj)
