jQuery UI datepicker - Trying to capture click eve

问题:

We're using jquery UI 1.8.23 at my workplace.

How can I capture the date clicked in datepicker, so I can format the current date into a datestamp and pass that value into a hidden form field?

Here's some code I've tried to get working:

$('.ui-state-default').live('click', function(){
    console.log('date clicked');
    var currentdate = $(this).text();
    var d = currentdate;
    var m = monthFormat($('.ui-datepicker-month').text());
    var y = $('.ui-datepicker-year').text();
    $('a.ui-state-default').removeClass('ui-state-highlight');
    $(this).addClass('ui-state-highlight');

    if (currentdate.length < 2) {
    d = "0" + currentdate;
    }
    var datestamp = y + "-" + m + "-" + d;
    console.log(datestamp);
    $('#dateHidden').val(datestamp);
});

Thanks for looking at my code I appreciate any help you guys can offer.

You don't need to do anything to format the date. The DatePicker widget does it for you. Just use the altField and altFormat properties:

$("#myDatePicker").datepicker({
    // The hidden field to receive the date
    altField: "#dateHidden",
    // The format you want
    altFormat: "yy-mm-dd",
    // The format the user actually sees
    dateFormat: "dd/mm/yy",
    onSelect: function (date) {
        // Your CSS changes, just in case you still need them
        $('a.ui-state-default').removeClass('ui-state-highlight');
        $(this).addClass('ui-state-highlight');
    }
});

jQuery Datepicker gives the option of formatting date. So why don't you make use of that?

$('element').datepicker({ dateFormat: 'dd-mm-yy' });

Also you don't need of a separate method to capture the click event. You the default method onSelect

$('input').datepicker({
 dateFormat: 'yy-mm-dd',
    onSelect: function (date) {
    //defined your own method here
    alert(date);
    }
})

$('#calendar').datepicker({
        inline: true,
        firstDay: 1,
        changeMonth: false,
        changeYear: true,
        showOtherMonths: true,
        showMonthAfterYear: false,
        yearRange: "2015:2025",      
        dayNamesMin: ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'],
        dateFormat: "yy-mm-dd",
        onSelect: function (date) {
            alert(date);
        }
    });

Your datepicker listens that.

see onSelect() function

Called when the datepicker is selected. The function receives the selected date as text and the datepicker instance as parameters. this refers to the associated input field.

$('.date-pick').datepicker( {
    onSelect: function(date) {
        //play with date here
    },
