Javascript：如何将纪元转换为 dd-mm-yyyy

Question

i have an epoch time: x = 1383483902000

I am trying to get a date like: dd-mm-yyyy and want to do this without additional library.

I have tried several ways and my last method end up like:

var date = new Date(Math.round(Number(x)));

but i get an ugly thing like: sun nov 03 2013 14:05:02 GMT+01:00

Answer 1

使用日期对象提取/格式化所需的部分：

var formattedDate = date.getUTCDate() + '-' + (date.getUTCMonth() + 1)+ '-' + date.getUTCFullYear()

Answer 2

The example below uses the UTC methods of the date object as you are dealing with epoch time (which is milliseconds since epoch in UTC):

var formatDate = function formatDate(date) {            // function for reusability
        var d = date.getUTCDate().toString(),           // getUTCDate() returns 1 - 31
            m = (date.getUTCMonth() + 1).toString(),    // getUTCMonth() returns 0 - 11
            y = date.getUTCFullYear().toString(),       // getUTCFullYear() returns a 4-digit year
            formatted = '';
        if (d.length === 1) {                           // pad to two digits if needed
            d = '0' + d;
        }
        if (m.length === 1) {                           // pad to two digits if needed
            m = '0' + m;
        }
        formatted = d + '-' + m + '-' + y;              // concatenate for output
        return formatted;
    },
    x = 1383483902000,                                  // sample time in ms since epoch
    d = new Date(x),                                    // convert to date object
    f = formatDate(d);                                  // pass to formatDate function to get dd-mm-yyyy
console.log(f);                                         // log output to console for testing

You can run this in the browser console as-is.

function formatDate(value: any): any{
    
    let date = new Date(Math.round(Number(value)));
    let day = ("0" + date.getDate()).slice(-2);
    let month = ("0" + (date.getMonth() + 1)).slice(-2);
    let formatDate = date.getFullYear()+"-"+(month)+"-"+(day) ;

    return formatDate;
}
