$(document).ready(function ()
	            dateFormat: 'dd-mm-yy',
	            changeMonth: true,
	            numberOfMonths: 1,
	            onClose: function (selectedDate) {
	                $("#txtend_date").datepicker("option", "minDate", selectedDate);
	            //Code to disable dates according to selection
	            beforeShowDay: filterDate
	    //By default no day selected in dropdown. So all the days will be displayed.
	    var str=0;
	    //Filterdate function to make the days enable/disable based on the selection.
	    var filterDate = function(date) {
	          return [true];
	          return [date.getDay() == str];
	    //Dropdown onchange function to set latest selection of dropdown.
	    function test()
	        str=$( "#drop1" ).val();
