Jquery datepicker beforeShow doesn't seem to be passing the instance
提问by NibblyPig
This is the JS Fiddle:
这是JS小提琴：
$("#datepicker").datepicker({ dateFormat: 'dd/mm/yy', beforeShowDay: myFunction});
function myFunction(input, inst)
{
alert(inst);
}
According to the documentation: http://docs.jquery.com/UI/API/1.8/Datepicker#event-beforeShow
根据文档：http: //docs.jquery.com/UI/API/1.8/Datepicker#event-beforeShow
the beforeshowDaymethod accepts input and inst. inst always seems to be undefined though. This is causing me some grief as I need to get hold of the datepicker itself.
该beforeshowDay方法接受 input 和 inst。inst 似乎总是未定义。这让我有些难过，因为我需要掌握日期选择器本身。
Is there a workaround?
有解决方法吗？

The beforeshowDaycallback has only one argument; a dateobject as per documentation. the beforeShowcallback however has 2 arguments as you've mentioned.
该beforeshowDay回调只有一个参数; date根据文档的对象。beforeShow但是，正如您所提到的，回调有 2 个参数。
beforeShowDay- http://docs.jquery.com/UI/API/1.8/Datepicker#event-beforeShowDay
beforeShowDay- http://docs.jquery.com/UI/API/1.8/Datepicker#event-beforeShowDay

As you can see, the beforeShowcallback correctly passes in the element and the instance. The beforeshowDaypasses in just a date object.
如您所见，beforeShow回调正确地传入了元素和实例。将beforeshowDay在短短的日期对象通过。
