how to refresh datepicker? function .datePickerMultiMonth()
提问by Markus
Really like datepicker. Thanks a lot for this great library!
真的很喜欢日期选择器。非常感谢这个伟大的图书馆！
I have got one question for you based in this example (inline datepicker):
基于这个例子（内联日期选择器），我有一个问题要问你：

http://www.kelvinluck.com/assets/jquery/datePicker/v2/demo/datePickerMultiMonth5.html
I added a "renderCallback" function to disable week days based on checkboxes... (e.g. when saturday-checkbox is checked disable all saturdays shown).
我添加了一个“renderCallback”函数来禁用基于复选框的工作日......（例如，当周六复选框被选中时禁用显示的所有周六）。
This works perfectly fine when initializing the calender with datePickerMultiMonth().
这在使用 datePickerMultiMonth() 初始化日历时非常有效。
But how can I refresh the inline calender when one of the checkboxes is changed (e.g. deselect monday-checkbox)?
但是，当其中一个复选框发生更改（例如取消选择 monday-checkbox）时，如何刷新内联日历？
As-is: when I select / deselect a checkbox the datepicker remains unchanged.. only after manually changing to the next month it updates and disables e.g. all mondays... this should immediately happen when changing the monday-checkbox.
原样：当我选择/取消选择一个复选框时，日期选择器保持不变..只有在手动更改到下个月后，它才会更新并禁用例如所有星期一......这应该在更改星期一复选框时立即发生。
Do you have any idea how I can refresh the datepicket? Thanks a lot for your help!
你知道我如何刷新 datepicket 吗？非常感谢你的帮助！
Cheers, Markus
干杯，马库斯

Probably the easiest way to solve the problem is to remove the existing calendar and then rerender it. e.g.:
解决问题的最简单方法可能是删除现有日历，然后重新渲染它。例如：
$mm.empty().datePickerMultiMonth({});
However, this has some drawbacks as the state of your date picker isn't maintained (e.g. displayed month, selected dates etc).
但是，这有一些缺点，因为您的日期选择器的状态没有得到维护（例如显示的月份、选定的日期等）。
So I just made some changes to the plugin and introduced a new method: dpmmRerenderCalendaron the multimonth picker (and the corresponding dpRerenderCalendaron the date picker itself).
所以我只是对插件进行了一些更改并引入了一种新方法：dpmmRerenderCalendar在多月选择器上（以及dpRerenderCalendar日期选择器本身上的相应方法）。
You can see an example of it in action here:
你可以在这里看到它的一个例子：

And can grab the latest plugin code from my site or the googlecode repository.
并且可以从我的站点或 googlecode 存储库中获取最新的插件代码。

After having a bit of a look at the source, it seems you'll have to do something like this:
稍微查看一下源代码后，您似乎必须执行以下操作：
$.event._dpCache[$('.date-pick')[0]._dpId]._applyRenderCallbacks()
or possibly this:
或者可能是这样的：
$.event._dpCache[$('.date-pick')[0]._dpId]._rerenderCalendar()
The $.event._dpCache[$('.date-pick')[0]._dpId]part is used to get the first internal DatePicker object matching the css '.date-pick', which is needed to access the internal _applyRenderCallbacksand _rerenderCalendarfunctions.
该$.event._dpCache[$('.date-pick')[0]._dpId]部分用于获取与 css 匹配的第一个内部 DatePicker 对象'.date-pick'，这是访问内部_applyRenderCallbacks和_rerenderCalendar函数所需的。
Unfortunately, this does access the internal structure of the plugin, so it is possible it might break when new versions are released, however I couldn't find any publicly accessible way to refresh the calendar.
不幸的是，这确实访问了插件的内部结构，因此在发布新版本时它可能会中断，但是我找不到任何可公开访问的方法来刷新日历。
