年份和月份选择的jQuery UI DatePicker不起作用

Question

I am using jquery datepicker as monthpicker and it is working but the only problem is if I select one month from calander then it shows that month in the input field, but when i click on that input field again then it doesn't show selected month but it shows current month.

HTML

<label for="startDate">Date :</label>
<input name="startDate" id="startDate" class="date-picker" />

JS

$(function() {
    $('.date-picker').datepicker( {
        changeMonth: true,
        changeYear: true,
        showButtonPanel: true,
        dateFormat: 'MM yy',
        onClose: function(dateText, inst) { 



            function isDonePressed(){
                            return ($('#ui-datepicker-div').html().indexOf('ui-datepicker-close ui-state-default ui-priority-primary ui-corner-all ui-state-hover') > -1);
                        }

                        if (isDonePressed()){

                            var month = $("#ui-datepicker-div .ui-datepicker-month :selected").val();
                            var year = $("#ui-datepicker-div .ui-datepicker-year :selected").val();
                            $(this).datepicker('setDate', new Date(year, month, 1));
                             console.log('Done is pressed')

                        }



        }
    });
});

Here is the fiddle for my question. http://jsfiddle.net/DBpJe/5103/

Answer 1

You would have to alter beforeShow like below and also since the months names are in String you would have to have an array like this to map the month against number

var monthNames = ["January", "February", "March", "April", "May", "June",
  "July", "August", "September", "October", "November", "December"
];
beforeShow: function(input, inst) {
  inst.dpDiv.addClass('month_year_datepicker')
  if ((datestr = $(this).val()).length > 0) {
    datestr = datestr.split(" ");
    year = datestr[1];
    month = monthNames.indexOf(datestr[0]);
    $(this).datepicker('option', 'defaultDate', new Date(year, month, 1));
    $(this).datepicker('setDate', new Date(year, month, 1));
    $(".ui-datepicker-calendar").hide();
  }
}

Here is demo 1

Or you can use this much better looking method to convert month to number

function getMonthFromString(mon){
   return new Date(Date.parse(mon +" 1, 2012")).getMonth()+1
}

Added a new function as well: restrict the to date is later than from date,

 <script type="text/javascript">
        $(function() {
     $( "#from, #to").datepicker(
                    {
                        dateFormat: "yy/mm",
                        changeMonth: true,
                        changeYear: true,
                        showButtonPanel: true,
                        showOn: "button",
                        buttonImage: "../../static/calendar.gif",
                        buttonImageOnly: true,
                        //buttonText: "Select date",
                        onClose: function(dateText, inst) {
                           var month = $("#ui-datepicker-div .ui-datepicker-month :selected").val();
                           var year = $("#ui-datepicker-div .ui-datepicker-year :selected").val();             
                           $(this).datepicker('setDate', new Date(year, month, 1));

                            function isDonePressed(){
                                return ($('#ui-datepicker-div').html().indexOf('ui-datepicker-close ui-state-default ui-priority-primary ui-corner-all ui-state-hover') > -1);
                            }

                            if (isDonePressed()){
                                var month = $("#ui-datepicker-div .ui-datepicker-month :selected").val();
                                var year = $("#ui-datepicker-div .ui-datepicker-year :selected").val();
                                $(this).datepicker('setDate', new Date(year, month, 1)).trigger('change');

                                 $('.from').focusout()//Added to remove focus from datepicker input box on selecting date
                            }
                        },

                        beforeShow : function(input, inst) {

                            inst.dpDiv.addClass('month_year_datepicker')

               if ((datestr = $(this).val()).length > 0) {
                   year = datestr.substring(datestr.length-4, datestr.length);
                   month = jQuery.inArray(datestr.substring(0, datestr.length-5), $(this).datepicker('option', 'monthNames'));
                   $(this).datepicker('option', 'defaultDate', new Date(year, month, 1));
                   $(this).datepicker('setDate', new Date(year, month, 1));    
               }
               var other = this.id == "from" ? "#to" : "#from";
               var option = this.id == "from" ? "maxDate" : "minDate";        
               if ((selectedDate = $(other).val()).length > 0) {
                   year = selectedDate.substring(selectedDate.length-4, selectedDate.length);
                   month = jQuery.inArray(selectedDate.substring(0, selectedDate.length-5), $(this).datepicker('option', 'monthNames'));
                   $(this).datepicker( "option", option, new Date(year, month, 1));
               }
           }
       });
       $("#btnShow").click(function(){ 
       if ($("#from").val().length == 0 || $("#to").val().length == 0){
           alert('All fields are required');
       }
       else{
           alert('Selected Month Range :'+ $("#from").val() + ' to ' + $("#to").val());
           }
       }),

       <!--reset-->
       $(".reset").click(function() {
           $(this).closest('form')[0].reset()
       });

});


        </script>

Answer 3

There is a way to do this by setting currentdate to the datetimepicker

$("#datepicker").datepicker("setDate", currentDate);

Here is the working sample JQFAQ Topic .

Answer 4

Try like that

$('#startDate').datepicker({
    dateFormat: 'mm/yy'
});

Edit: I saw now what you said. The same is going on with that ^
