Javascript 日期选择器类型错误问题：日期设置未定义不可选择=（otherMonth&；！selectOtherMonths）| |！日期设置[0]||

您好，我有一个日期选择器问题，如果我想为所有期间阻止一天，我有一个带“是”的var（字符串），否则如果我有“”，我不想阻止

<script>
    jQuery(document).ready(function(){

        var sunday = ""; // here use a called php to get a value from db ex. 
            "<?php print get_post_meta(get_the_ID(), "_domenica", true); ?>";
        var monday = "";
        var tuesday = "yes";
        var wednesday = "";
        var thursday  = "";
        var friday = "";
        var saturday = "yes";


        jQuery('#dateEscluseEventCalendar').datepicker({
            minDate: new Date(),
            beforeShowDay: function (day) {
                var day = day.getDay();
                var closeDays = [[sunday],[monday],[tuesday],
                [wednesday],[thursday],[friday],[saturday]];
                for (var i = 0; i < closeDays.length; i++){
                    if (day == i && closeDays[i][0]== "yes" ) 
                        return [false]; 

                }

        }});

});

你有解决办法吗？？
