[jquery] How to get date, month, year in jQuery UI datepicker?

I have this sample code:

<div id="calendar"></div>
$(document).ready(function()  {
    $('#calendar').datepicker({
      dateFormat: 'yy-m-d',
      inline: true,
      onSelect: function(dateText, inst) { 
            var month = dateText.getUTCMonth();
            var day = dateText.getUTCDate();
            var year = dateText.getUTCFullYear();
            alert(day+month+year);
     } 
    });
});

When I run the code, there is an error. How to get this (date, month, year)?

$("#date").datepicker('getDate').getMonth() + 1; 

The month on the datepicker is 0 based (0-11), so add 1 to get the month as it appears in the date.

what about that simple way)

$(document).ready ->
 $('#datepicker').datepicker( dateFormat: 'yy-mm-dd',  onSelect: (dateStr) ->
    alert dateStr # yy-mm-dd
    #OR
    alert $("#datepicker").val(); # yy-mm-dd

Hi you can try viewing this jsFiddle.

I used this code:

var day = $(this).datepicker('getDate').getDate();  
var month = $(this).datepicker('getDate').getMonth();  
var year = $(this).datepicker('getDate').getYear();  

I hope this helps.

Use the javascript Date object.

$(document).ready(function()  {
    $('#calendar').datepicker({
      dateFormat: 'yy-m-d',
      inline: true,
      onSelect: function(dateText, inst) { 
            var date = new Date(dateText);
            // change date.GetDay() to date.GetDate()
            alert(date.getDate() + date.getMonth() + date.getFullYear());
     } 
    });
});
