How to add onChange event to dropdown boxes of JQuery.DatePicker

问题

I have the following situation: Fiddle

What I want, is to add an onChange event to the dropdown boxes of the datepicker so that I will be able to capture the selected month/year in the text box above as a new value is selected from the calendar.

PS: Inspecting the relevant dropdown boxes, there is already an onChange command assigned that looks like

onchange="DP_jQuery_1353406309923.datepicker._selectMonthYear('#datepicker', this, 'M');"

I don't want to overwrite this.

Thanks in advance

Use the onChangeMonthYear option:

onChangeMonthYear

Called when the datepicker moves to a new month and/or year. The function receives the selected year, month (1-12), and the datepicker instance as parameters. this refers to the associated input field.

$(function() {
    $( "#datepicker1" ).datepicker({
      changeMonth: true,
      changeYear: true,
      dateFormat: 'MM yy',
      altField: "#id",
      altFormat: "mm/yy",
      onChangeMonthYear: function(year, month, oDatepicker) {
        alert('Year: ' + year + ', Month: ' + month);
      }
    });
});​
