使用beforeShowDay和對象數組排除日期在jQuery datepicker

Question

我有一個對象數組，什麼是確定日期是否在數組中，以便它不能在jQuery日期選擇器中選擇的最佳方法是什麼。如果需要，我可以將DateValue存儲爲日期。

var EventDates = [{"DateID: "1", DateValue: "3/1/2011", FormattedDate: Tue, Mar 1 2011"}, 
     {"DateID: "2", DateValue: "3/2/2011", FormattedDate: Wed, Mar 2 2011"}] 


$('.juidateicon_ext').datepicker({ 
     showOn: "button", 
     buttonImage: "/Content/images/icons/calendar.gif", 
     buttonImageOnly: true, 
     showOn: 'both', 
     beforeShowDay: eventDays 
}); 

function eventDays(date) { 

    1. Code to determine if "date" is in DateValue in the EventDates Array 
    2. If date exist, return [false, ""];else return [true, ""]; 
}

我把清理你EventDates陣列的自由：

var EventDates = [{ 
    "DateID": "1", 
    "DateValue": "3/1/2011", 
    "FormattedDate": "Tue, Mar 1 2011"}, 
{ 
    "DateID": "2", 
    "DateValue": "3/2/2011", 
    "FormattedDate": "Wed, Mar 2 2011" 
}]; 

而這裏的eventDays功能：

function eventDays(date) { 
    var length = EventDates.length, i = 0; 
    var event = null, eventDate = false; 

    while (i < length && !eventDate) { 
     event = EventDates[i]; 
     eventDate = new Date(event.DateValue).valueOf() === date.valueOf(); 
     i++; 
    } 

    return [!eventDate, '']; 
}
