Remember the date selected in datepicker even after refresh - php

Question

I just want to know if how can my datepicker remembered what month has been selected. For example, I choose June 1, 2013 even after refresh the month to be displayed in date picker is still June.
Here is my code.
$(function() {
var startDate;
var endDate;
var selectCurrentWeek = function() {
window.setTimeout(function () {
$('#weekpicker').datepicker('widget').find('.ui-datepicker-current-day a').addClass('ui-state-active')
}, 1);
}
$('#weekpicker').datepicker( {
changeYear:true,
changeMonth:true,
showButtonPanel:true,
onSelect: function(dateText, inst) {
var date = $(this).datepicker('getDate');
startDate = new Date(date.getFullYear(), date.getMonth(), date.getDate() - date.getDay() + 1);
endDate = new Date(date.getFullYear(), date.getMonth(), date.getDate() - date.getDay() + 7);
var dateFormat = inst.settings.dateFormat || $.datepicker._defaults.dateFormat;
$('#weekpicker').val($.datepicker.formatDate( dateFormat, startDate, inst.settings )
+ ' - ' + $.datepicker.formatDate( dateFormat, endDate, inst.settings ));
selectCurrentWeek();
},
beforeShow: function() {
selectCurrentWeek();
},
beforeShowDay: function(date) {
var cssClass = '';
if(date >= startDate && date <= endDate)
cssClass = 'ui-datepicker-current-day';
return [true, cssClass];
},
onChangeMonthYear: function(year, month, inst) {
selectCurrentWeek();
}
}).datepicker('widget').addClass('ui-weekpicker');
$('.ui-weekpicker .ui-datepicker-calendar tr').live('mousemove', function() { $(this).find('td a').addClass('ui-state-hover'); });
$('.ui-weekpicker .ui-datepicker-calendar tr').live('mouseleave', function() { $(this).find('td a').removeClass('ui-state-hover'); });
});

Answer 1

You would need to deal with sessions.
Once the website is refreshed, just add the date into a PHP session.
You can read more about sessionsn here and a more concrete example for what you are looking for, here.

Well, you added a space to "" in the if statement. And I guess I have bad logic anyways - you should probably use "&&" instead of "||". So please use the following code exactly as is:
$('input[type=text][id*=myDate1]').datepicker({
showOn: "button",
buttonImage: "/Images/cal.gif",
buttonImageOnly: true,
onSelect: function (dateText, inst) { $('#HiddenField1').val(dateText) },
changeMonth: true,
changeYear: true,
showWeek: true,
firstDay: 1
});
var theDate;
if ($('#HiddenField1').val() != "" && $('#HiddenField1').val() != null) {
theDate = $('#HiddenField1').val();
}
else {
theDate = new Date();
}
alert(theDate);
$('input[type=text][id*=myDate1]').datepicker("option", "showAnim", 'bounce');
$('input[type=text][id*=myDate1]').datepicker("option", "dateFormat", 'dd/mm/yy');
$('input[type=text][id*=myDate1]').datepicker("option", "altFormat", 'dd/mm/yy');
$('input[type=text][id*=myDate1]').datepicker('setDate', theDate);
