maxDate option in datepicker

Tried the following code.It works fine for me.

    var date = new Date("2013-07-15");
    var currentMonth = date.getMonth();
    var currentDate = date.getDate();
    var currentYear = date.getFullYear();
    $("#datepicker" ).datepicker( "option", "maxDate", new Date(currentYear, currentMonth, currentDate));

Example fiddle I created:FIDDLE

Try This to choose max/min dates from month and year datepicker.

See this fiddle for the full solution: Month/Year Picker @ JSFiddle

var searchMinDate = "-2y";
var searchMaxDate = "-1m";
if ((new Date()).getDate() <= 5) {
    searchMaxDate = "-2m";
}
$("#txtFrom").datepicker({
    dateFormat: "M yy",
    changeMonth: true,
    changeYear: true,
    showButtonPanel: true,
    showAnim: "",
    minDate: searchMinDate,
    maxDate: searchMaxDate,
    showButtonPanel: true,
    beforeShow: function (input, inst) {
        if ((datestr = $("#txtFrom").val()).length > 0) {
            var year = datestr.substring(datestr.length - 4, datestr.length);
            var month = jQuery.inArray(datestr.substring(0, datestr.length - 5), "#txtFrom").datepicker('option', 'monthNamesShort'));
        $("#txtFrom").datepicker('option', 'defaultDate', new Date(year, month, 1));
                $("#txtFrom").datepicker('setDate', new Date(year, month, 1));
            }
        },
        onClose: function (input, inst) {
            var month = $("#ui-datepicker-div .ui-datepicker-month :selected").val();
            var year = $("#ui-datepicker-div .ui-datepicker-year :selected").val();
            $("#txtFrom").datepicker('option', 'defaultDate', new Date(year, month, 1));
            $("#txtFrom").datepicker('setDate', new Date(year, month, 1));
            var to = $("#txtTo").val();
            $("#txtTo").datepicker('option', 'minDate', new Date(year, month, 1));
            if (to.length > 0) {
                var toyear = to.substring(to.length - 4, to.length);
                var tomonth = jQuery.inArray(to.substring(0, to.length - 5), $("#txtTo").datepicker('option', 'monthNamesShort'));
                $("#txtTo").datepicker('option', 'defaultDate', new Date(toyear, tomonth, 1));
                $("#txtTo").datepicker('setDate', new Date(toyear, tomonth, 1));
            }
        }
    });
    $("#txtTo").datepicker({
        dateFormat: "M yy",
        changeMonth: true,
        changeYear: true,
        showButtonPanel: true,
        showAnim: "",
        minDate: searchMinDate,
        maxDate: searchMaxDate,
        showButtonPanel: true,
        beforeShow: function (input, inst) {
            if ((datestr = $("#txtTo").val()).length > 0) {
                var year = datestr.substring(datestr.length - 4, datestr.length);
                var month = jQuery.inArray(datestr.substring(0, datestr.length - 5), $("#txtTo").datepicker('option', 'monthNamesShort'));
                $("#txtTo").datepicker('option', 'defaultDate', new Date(year, month, 1));
                $("#txtTo").datepicker('setDate', new Date(year, month, 1));
            }
        },
        onClose: function (input, inst) {
            var month = $("#ui-datepicker-div .ui-datepicker-month :selected").val();
            var year = $("#ui-datepicker-div .ui-datepicker-year :selected").val();
            $("#txtTo").datepicker('option', 'defaultDate', new Date(year, month, 1));
            $("#txtTo").datepicker('setDate', new Date(year, month, 1));
            var from = $("#txtFrom").val();
            $("#txtFrom").datepicker('option', 'maxDate', new Date(year, month, 1));
            if (from.length > 0) {
                var fryear = from.substring(from.length - 4, from.length);
                var frmonth = jQuery.inArray(from.substring(0, from.length - 5), $("#txtFrom").datepicker('option', 'monthNamesShort'));
                $("#txtFrom").datepicker('option', 'defaultDate', new Date(fryear, frmonth, 1));
                $("#txtFrom").datepicker('setDate', new Date(fryear, frmonth, 1));
            }

        }
    });

Also add this to a style block as mentioned above:

.ui-datepicker-calendar { display: none !important; }
