Closing jQuery Datepicker When Closing jQuery Dialog

First time here, and more of a web designer than programmer, so be gentle! ;o) Anyway, as the title suggests, I have a dialog window that's opened and within that, a datepicker. What I want it that, if the user opens the datepicker, and then clicks the开发者_JAVA百科 dialog window's close button, the datepicker is also closed.

Here's what I've got at present:

        <!--// Modal Windows -->        
        $.ui.dialog.defaults.bgiframe = true;
        $(function() {
            $('#advanced_search').dialog({
                autoOpen: false,
                width: 600,
                height: 400,
                modal: true,
                resizable: false,
                draggable: false,
                title: 'Advanced Search',
            });
            $('.adv_search').click(function() {
                $('#advanced_search').dialog('open');
            });
        });

        <!--// Date Picker -->
        $("#advanced_search .start_date").datepicker({
            dateFormat: 'dd/mm/yy',
            showButtonPanel: true,
            duration: 0,
            constrainInput: true,
            showOn: 'button',               
            buttonImage: '/img/icons/50.png',
            buttonImageOnly: true                               
        });
        $("#advanced_search .end_date").datepicker({
            dateFormat: 'dd/mm/yy',
            showButtonPanel: true,
            duration: 0,
            constrainInput: true,
            showOn: 'button',
            buttonImage: '/img/icons/50.png',
            buttonImageOnly: true                               
        });

But I'm a bit flummoxed as to how to do this. Anyone got any advice? It'd be much appreciated!

Thanks Phil

Add the close callback to your dialog like this:

$(function() {
   $('#advanced_search').dialog({
        autoOpen: false,
        width: 600,
        height: 400,
        modal: true,
        resizable: false,
        draggable: false,
        title: 'Advanced Search',
        close: function() { 
          $("#advanced_search .start_date").datepicker('hide');
          $("#advanced_search .end_date").datepicker('hide');
        } 
    });
    $('.adv_search').click(function() {
        $('#advanced_search').dialog('open');
    });
});

Here's an all-inclusive approach that's slightly better, simpler selectors and the date pickers aren't created until the dialog is actually opened, so if a user never goes into it, less script running:

$(function() {
   $('#advanced_search').dialog({
        autoOpen: false,
        width: 600,
        height: 400,
        modal: true,
        resizable: false,
        draggable: false,
        title: 'Advanced Search',
        close: function() { 
          $("#advanced_search .start_date").datepicker('hide');
          $("#advanced_search .end_date").datepicker('hide');
        }, 
        open: function(event, ui) {
          $(".start_date, .end_date", ui).datepicker({
            dateFormat: 'dd/mm/yy',
            showButtonPanel: true,
            duration: 0,
            constrainInput: true,
            showOn: 'button',               
            buttonImage: '/img/icons/50.png',
            buttonImageOnly: true                               
          });
        }
    });
    $('.adv_search').click(function() {
        $('#advanced_search').dialog('open');
    });
});
