jQuery DatePicker validation: Start Date should be Today and End Date not less than Start Date

tandoh says:

 $(function () {

            $("#txtFrom").datepicker({

                minDate: new Date(),

                onSelect: function (selected) {

                    var dt = new Date(selected);

                    dt.setDate(dt.getDate() + 1);

                    $("#txtTo").datepicker("option", "minDate", dt);

                }

            });

            $("#txtTo").datepicker({

                onSelect: function (selected) {

                    var dt = new Date(selected);

                    dt.setDate(dt.getDate() - 1);

                    $("#txtFrom").datepicker("option", "maxDate", dt);

                }

            });

        });

 replace above code with below

$(function () {
    $("[id*=txtFrom]").datepicker({
        minDate: new Date(),
        onSelect: function (selected) {
            var dt = new Date(selected);
            dt.setDate(dt.getDate() + 1);
            $("#txtTo").datepicker("option", "minDate", dt);
        }
    });
    $("[id*=txtTo]").datepicker({
        onSelect: function (selected) {
            var dt = new Date(selected);
            dt.setDate(dt.getDate() - 1);
            $("#txtFrom").datepicker("option", "maxDate", dt);
        }
    });
});
