It can be achieved without moment.js, but I suggest you use it
不用moment.js也可以实现，但是我建议你使用它
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

If the date string is always in ISO format, you can also use regex to reformat without other library:
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}).*/, '--')

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:
您可以使用 JavaScript date() 内置函数来获取您想要的部分日期/时间。例如显示时间是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
获取年、月、日、星期几使用
getFullYear();
getMonth();
getDate();
getDay();
getFullYear();
获取月份（）；
获取日期（）；
getDay();
To get the date you posted:

Using Date.toJSON()
使用 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"));回答by SkipHyman
If you're looking to do this in vanilla javascript, @Ivan Mladenov's answer is great and can be consolidated slightly using padStart.
如果您想在 vanilla javascript 中执行此操作，@Ivan Mladenov 的回答很棒，可以使用padStart稍微巩固一下。
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}`)
