Showing result is

also i have tried xxx.months(), but it's return result is 7

but i want jan,feb,mar,......dec. hmm What can i do?

回答1:

There happens to be a function for that:

moment.monthsShort()
// ["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"]

Or the same using manual formatting:

Array.apply(0, Array(12)).map(function(_,i){return moment().month(i).format('MMM')})

I guess you want to display all names utilizing Moment.js locale data, which is a reasonable approach.

回答2:

Using moment.js you have the following methods:

moment.month() // long names

returns:

[ 'January',
  'February',
  'March',
  'April',
  'May',
  'June',
  'July',
  'August',
  'September',
  'October',
  'November',
  'December' ]

and

moment.monthsShort() // short names

returns:

["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"]

Why does the year matter? Month names don't change.

You could get month names from Moment like so:

var m = moment();
for (var i = 0; i < 12; i++) {
 console.log(m.months(i).format('MMMM'));
}

/**

 * @param lang {string} Language code
 * @param frmt {string} Possible values: {'M','MM','MMM','MMMM'}
 * @return the array of month names
 */
function getMonthNames(lang, frmt) {
  var userLang = moment.lang();            // Save user language
  moment.lang(lang);                       // Switch to specified language
  var months = [];                         // Months array
  var m = moment("2011");                  // Create a moment in 2011
  for (var i = 0; i < 12; i++)             // Loop from 0 to 12 (exclusive)
    months.push(m.months(i).format(frmt)); // Append the formatted month
  moment.lang(userLang);                   // Restore user language
  return months;                           // Return the array of months
}

function println(text) {
  text = arguments.length > 1 ? [].join.call(arguments, ' ') : text;
  document.getElementById('disp').innerHTML += text + '\n';
}

println('English:', getMonthNames('en-US', 'MMM'));
println('Bengali:', getMonthNames('bn', 'MMM'));
println('Español:', getMonthNames('es', 'MMM'));

#disp {
  white-space: pre;
  font-family: monospace;
}

You can use following function to get a list of Weekdays and Months for listing purpose -

var iIndex, 
sArrMonths, sMonth;
for(iIndex = 0; iIndex < 12; iIndex++)
{
    sMonth = moment.localeData().months(moment([0,iIndex]), "");
    sArrMonths.push(sMonth);
}

You are going to have to access the months from an array:

var months = [ "January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December" ];

var monthInt = new Date().getMonth();
var monthString = months[monthInt];

I needed an array with months number and months name to display them in ng-optiosn, so I extended a little bit Klaster_1's solution.

Array.apply(0, Array(12)).map(
                    function(_,i){
                          var elem    ={};
                          elem.id     = parseInt(i+1);
                          elem.name   = moment().month(i).format('MMM'); 
                          return elem;
                    }
              )
