Validate From Date and To Date in Jquery Datepicker

If you want to validate TO date never be greater than FROM date. We can easily use jquery date picker options:
Let we have two input html text box,
  <label>From Date</label><input type="text" id="txtfrmdate" readonly/>
  <label>To Date</label><input type="text" id="txtTodate" readonly/>

Then Your javascript Code would be,

           $("#txtfrmdate").datepicker({
                    numberOfMonths: 1,
                    maxDate: 0,
                    dateFormat: 'yy-mm-dd',
                    onSelect: function (selected) {
                        $("#txtTodate").datepicker("option", "minDate", selected)
                    }
                });

                $("#txtTodate").datepicker({
                    numberOfMonths: 1,
                    maxDate: 0,
                    dateFormat: 'yy-mm-dd',
                    onSelect: function (selected) {
                        $("#txtfrmdate").datepicker("option", "maxDate", selected)
                    }
                });
