输入日历跳转到下一个输入

Question

我正在使用这个日历，并且“我被迫使用它”，我想知道你是否可以帮我解决一个小问题。

日历：http://www.bulgaria-web-developers.com/projects/javascript/calendar/

我有2个此日历所在的输入字段，

<input type="text" id="cr_date_from" />
<input type="text" id="cr_date_to" />

在“date_from”中选择日期之后，我需要它跳转到“date_to”并且具有与date_from字段中选择的日期相同的日期。因为当人们提前几个月选择一个日期时，这不会引起混淆，也不会在date_to中一直滚动到那个日期......

我已经尝试了一段时间没有运气，所以我希望你们能够帮助我......

感谢所有帮助！

这里也是那些感兴趣的人的javascript ...
