Populate date dropdown with datepicker

Question

I have a dropdown list where the user can choose month/day/year, but to make it a bit quicker for the user i have added in the jquery datepicker, which is working ok except is there a way that once the user has selected a date from the calendar that it automatically populates the drop down fields? As i have these dropdowns set to import into my database already.

Current drop downs

<dd>
        <select id="month_of_purchase" name="entry[month_of_purchase]">
            <option value="">Month</option>
            <option value="1">Jan</option>
            <option value="2">Feb</option>

});

Answer 1

$(document).ready(function(){
    $("#datepicker").datepicker({dateFormat: 'mm-dd-yy',
        onSelect: function(dateText, inst) {
            var mydate= $(this).datepicker("getDate");
            $("#month_of_purchase").val(mydate.getMonth()+1);            
            $("#day_of_purchase").val(mydate.getDate());
            $("#year_of_purchase").val(mydate.getFullYear());
        }
    });
});

Answer 2

try this way

JQUERY CODE:

$(document).ready(function () {
 $("#tx").datepicker({
    buttonImage: 'http://icongal.com/gallery/image/203336/birthday_rose_for_kdc_kdc_rose_love_flower_valentine_rose.png',
    buttonImageOnly: true,
    changeMonth: true,
    changeYear: true,
    showOn: 'both'
});

$("#tx").on('change', function () {
    var dt = ($(this).val()).split('/');
    var mon = dt[0];
    var day = dt[1];
    var year = dt[2];
    $('#month_of_purchase').val(mon).attr("selected", "selected");
    $('#day_of_purchase').val(day).attr("selected", "selected");
    $('#year_of_purchase').val(year).attr("selected", "selected");
});

});`

HTML CODE:

 <input type="hidden" id="tx" />
 <select id="month_of_purchase" name="entry[month_of_purchase]">

EDIT 1:

only modification i have done is that, i have converted the date value from 1,2,3... to 01,02,03...... under value attribute of option tags.

EDIT 2:

Trigger a date-picker over a image rather than a traditional text box.

Happy Coding:)
