Jquery UI Datepicker onclick事件

我想在用户点击活动日期时打开一个url。 我使用jQuery UI Datepicker，我没有看到问题出在哪里。

这是我的代码：

 $(document).ready(function() { var events = [ { Title: "titre", Idevent: "1", Date: new Date("05/20/2012")}, { Title: "test24", Idevent: "3", Date: new Date("06/14/2012")} ]; $("#calendarcaps").datepicker({ beforeShowDay: function(date) { var result = [true, '', null]; var matching = $.grep(events, function(event) { return event.Date.valueOf() === date.valueOf(); }); if (matching.length) { result = [true, 'highlight', null]; } return result; }, onSelect: function(dateText) { var date, selectedDate = new Date(dateText), i = 0, event = null; while (i < events.length && !event) { date = events[i].Date; if (selectedDate.valueOf() === date.valueOf()) { event = events[i]; } i++; } if (event) { window.location.href = "test.php?id=" + event.Idevent; } } }); });​  

谁能看到我做错了什么？
