Display time using moment.js only if not 00:00:00

Question

How do I display the time using moment.js only if not 00:00:00? The following works, however, seems like a bit of a kludge. Thanks

function convertDate(d) {
    var l=d.length;
    var f='DD/MM/YYYY'+((l==19 && d.substr(l - 8)=='00:00:00' )?'':', h:mm:ss a');
    return moment(d).format(f);
}
console.log(convertDate("2014-11-02 02:04:05"));
console.log(convertDate("2014-11-02 00:00:00"));

Answer 1

you can use below function to get the format

var getDate = function(d)
{
     var format = "DD/MM/YYYY h:mm:ss a";
    if(moment(d).startOf('day').valueOf() === moment(d).valueOf())
    {
      format = "DD/MM/YYYY"
    }
    return moment(d).format(format);
}

console.log(getDate("2014-11-02 02:04:05"));
console.log(getDate("2014-11-02 00:00:00"));

it compare the ticks from start of day to the input time, if both are same, it means the time is zero.

You could parse the date with moment and then use different formats according to hours/minutes/seconds values.

var date = moment(d);
var result;
if (date.hours() == 0 && date.minutes() == 0 && date.seconds() == 0) {
    // format without hours/minutes/seconds
    result = date.format('DD/MM/YYYY');
}
else {
    // complete format
    result = date.format('DD/MM/YYYY, h:mm:ss a'); // or whatever it is
}
