JS time conversion standard format, timestamp conversion standard format

The front end often needs to use a time format of ：

2020-08-10 10:00:34

I put together a generic function
Now go straight to the code , You can use it ：

One 、 Convert current time to standard format ：

function getFormatDate() {
    
    var date = new Date();
    var month = date.getMonth() + 1;
    var day = date.getDate();
    var hour = date.getHours();
    var minutes = date.getMinutes();
    var seconds = date.getSeconds();
    month = (month<10)? '0'+ month : month;
    day = (day<10)? '0'+ day : day;
    hour = (hour<10)? '0'+ hour : hour;
    minutes = (minutes<10)? '0'+ minutes : minutes;
    seconds = (seconds<10)? '0'+ seconds : seconds;
    var currentDate = date.getFullYear() + "-" + month + "-" + day
            + " " + hour + ":" + minutes + ":" + seconds;
    return currentDate;
}
console.log(getFormatDate()) //2020-08-10 10:00:34

This new Date() In fact, it is the time taken from the computer system , If you find that the time you get does not match the real time , Remember to adjust the system time to match the network time

Two 、 Timestamp conversion to standard format ：

This scenario is often used when the data returned from the back end is timestamp , The front-end manual conversion processing is required

        function formatDate(datetime) {
    
            var date = new Date(datetime); //datetime Timestamp 13 Bit millisecond level , If 10 Bit multiplication 1000
            var month = ("0" + (date.getMonth() + 1)).slice(-2),
                sdate = ("0" + date.getDate()).slice(-2),
                hour = ("0" + date.getHours()).slice(-2),
                minute = ("0" + date.getMinutes()).slice(-2),
                second = ("0" + date.getSeconds()).slice(-2);
            var thatDate = date.getFullYear() + "-" + month + "-" + sdate + " " + hour + ":" + minute + ":" + second;
            //  return 
            return thatDate;
        }
        console.log(formatDate(1599085447000)) //2020-09-03 06:24:07

If what is needed is not ‘2020-09-03 06:24:07’ It is ‘2020 year 09 month 03 Japan 06:24:07’, Just change the concatenated string
