在javascript中格式化日期字符串

Question

您好，每个我都有这样的 iso 格式的字符串类型的日期字段： const date = "2017-06-10T16:08:00: 我想以某种方式以如下格式编辑字符串：10-06-2017 但我'正在努力实现这一目标。我在“T”字符之后剪切了子字符串

Answer 1

It can be achieved without moment.js, but I suggest you use it

var date = new Date("2017-06-10T16:08:00");

var year = date.getFullYear();
var month = date.getMonth()+1;
var day = date.getDate();

if (day < 10) {
  day = '0' + day;
}
if (month < 10) {
  month = '0' + month;
}

var formattedDate = day + '-' + month + '-' + year

Answer 2

Use Moment.js and the .format function.

moment('2017-06-10T16:08:00').format('MM/DD/YYYY');

Will output

06/10/2017

Beside the format function Moment.js will enrich you will alot more useful functions.

Answer 3

如果日期字符串始终为 ISO 格式，您还可以使用正则表达式重新格式化，而无需其他库：

date.replace(/(\d{4})\-(\d{2})\-(\d{2}).*/, '$3-$2-$1')

Answer 4

I would like to suggest to use moment js find it - http://momentjs.com/docs/

and use it like

    moment(date.toString()).format("MM/DD/YYYY")

Answer 5

You can use the JavaScript date() built in function to get parts of the date/time you want. For example to display the time is 10:30:

<script>
var date = new Date();
 var min = date.getMinutes();
  var hour = date.getHour();
   document.write(hour+":"+min);
   </script>

To get the year, month, date, day of week use

• getFullYear();

• getMonth();

• getDate();

• getDay();

To get the date you posted:

Answer 6

Using Date.toJSON()

 function formatDate(userDate) { // format from M/D/YYYY to YYYYMMDD return (new Date(userDate).toJSON().slice(0,10).split('-').reverse().join('-')); } console.log(formatDate("2017-06-10T16:08:00"));

Answer 7

If you're looking to do this in vanilla javascript, @Ivan Mladenov's answer is great and can be consolidated slightly using padStart .

const date = new Date()
const year = date.getFullYear()
const month = String(date.getMonth() + 1).padStart(2, '0')
const day = String(date.getDate()).padStart(2, '0')

console.log(`${day}-${month}-${year}`)
