[JUNZHONG]

you demo for date filtering on IE11 is not working correctly.
http://paramquery.com/pro/demos/filter_date

The date picker keeps on popping up even after selecting date.
Please advise.

That is caused by the below code in IE for datepicker, please comment / remove it.

Code: [Select]

           onClose: function (evt, ui) {
                 $(this).focus();
           }
