js date format conversion (reproduced)

1. The current time is converted to "yyyy-MM-dd HH:MM:SS"

function getNowFormatDate() {
    var date = new Date();
    var seperator1 = "-";
    var seperator2 = ":";
    var month = date.getMonth() + 1;
    var strDate = date.getDate();
    if (month >= 1 && month <= 9) {
        month = "0" + month;
    }
    if (strDate >= 0 && strDate <= 9) {
        strDate = "0" + strDate;
    }
    var currentdate = date.getFullYear() + seperator1 + month + seperator1 + strDate
            + " " + date.getHours() + seperator2 + date.getMinutes()
            + seperator2 + date.getSeconds();
    return currentdate;
}

2. Convert any date to "yyyy-MM-dd HH:MM:SS" and pass the date variable as a parameter.

3. Convert any date to "yyyy-MM-dd", just change it slightly.

       // Get the current date and time format "yyyy-MM-dd"
        function getFormatDate(date) {
            //var date = new Date();
            var seperator1 = "-";
            var month = date.getMonth() + 1;
            var strDate = date.getDate();
            if (month >= 1 && month <= 9) {
                month = "0" + month;
            }
            if (strDate >= 0 && strDate <= 9) {
                strDate = "0" + strDate;
            }
            var currentdate = date.getFullYear() + seperator1 + month + seperator1 + strDate;
                 
            return currentdate;
        }

4. Convert any date to " HH:MM:SS ", just change it slightly, omit it.

5. Convert the specified format to "yyyy-MM-dd" format, the code is as follows:

var oldTime = (new Date("2012/12/25 20:11:11")).getTime();
var curTime = new Date(oldTime).format("yyyy-MM-dd");
console.log(curTime);

6. Convert "timestamp" to "year month day" format.

For example the following code:

var da = 1402233166999;
da = new Date(da);
var year = da.getFullYear();
var month = da.getMonth()+1;
var date = da.getDate();
console.log([year,month,date].join('-'));
