用于阻止特定日期（假期）的引导日期选择器配置

有谁知道如何配置日期选择器不显示特定日期（例如 7 月 4 日）？这似乎可以使用 beforeShowDay 来完成，但我并不肯定。

http://jsfiddle.net/Lr3taznx/

//a array of dates that should be blocked
var forbidden=['12/25/2014','12/24/2014']

$('#datepicker').datepicker({
    beforeShowDay:function(Date){
        //
        var curr_day = Date.getDate();
        var curr_month = Date.getMonth()+1;
        var curr_year = Date.getFullYear();        
        var curr_date=curr_month+'/'+curr_day+'/'+curr_year;        

        if (forbidden.indexOf(curr_date)>-1) return false;        
    }
})

OR:

var forbidden=['2014-12-25','2014-12-24']

$('#datepicker').datepicker({
    beforeShowDay:function(Date){
        var curr_date = Date.toJSON().substring(0,10);

        if (forbidden.indexOf(curr_date)>-1) return false;        
    }
})
