javascript - beforeShowDay 每天调用两次

Question

我如何防止函数 beforeShowDay 调用一天多次？ jquery datepicker 有两个月。

30.01.2013 -> month side jan
31.01.2013 -> month side jan
01.02.2013 -> month side jan (last invisible day / placehoder)
02.02.2013 -> month side jan (last invisible day / placehoder)
03.02.2013 -> month side jan (last invisible day / placehoder)
----------------------------    
28.01.2013 -> month side feb (first invisible day / placehoder)
29.01.2013 -> month side feb (first invisible day / placehoder)
30.01.2013 -> month side feb (first invisible day / placehoder)
31.01.2013 -> month side feb (first invisible day / placehoder)
01.02.2013 -> month side feb
01.02.2013 -> month side feb
02.02.2013 -> month side feb
02.02.2013 -> month side feb
03.02.2013 -> month side feb
03.02.2013 -> month side feb
04.02.2013 -> month side feb
04.02.2013 -> month side feb

我用 beforeShowDay 计算天数，如果某些天调用两次，结果不正确...我怎样才能防止天数重复调用？

您好!

根据 this jquery 用户界面示例:

$(function() {
    $( "#datepicker" ).datepicker({
        showOtherMonths: true,
        selectOtherMonths: true,
        numberOfMonths: 2
    });
});
