以一致的格式获取日期

Question

I am having a function which return the date based on some condition (last 30 day).

 const start = new Date(); start.setTime(start.getTime() - 3600 * 1000 * 24 * 30); const startTime = start.toLocaleString().split(",")[0]; console.log(startTime)

In Mac OS,I am getting the output in dd/mm/yyyy format (which is the desired format).

But in Windows, I am getting the output in mm/dd/yyyy. How can I make it consistent irespective of platform. Desired format is dd/mm/yyy

Answer 1

Use toLocaleDateString with 'en-GB'

 const start = new Date(); start.setDate(start.getDate() - 30) const startTime = start.toLocaleDateString('en-GB'); console.log(startTime)

Answer 2

Use toLocaleDateString with locale (and optional options)

The en-GB locale seems what you want here

 const options = {year: 'numeric', month: 'numeric', day: 'numeric' }; // default options const start = new Date(); start.setTime(start.getTime() - 3600 * 1000 * 24 * 30); console.log(start.toLocaleDateString('en-GB', options));

Answer 3

function SetShortDateTime(d) {
const monthList = [
    "01",
    "02",
    "03",
    "04",
    "05",
    "06",
    "07",
    "08",
    "09",
    "10",
    "11",
    "12"
];


const yr = d.getFullYear();
const mnt = monthList[d.getMonth()];
const day = d.getDate() < 9 ? "0" + d.getDate() : d.getDate();

return [day, mnt, yr].join("/") ;
}
