Question

昨天我已经问了一个关于datepicker的问题，但现在我遇到了一个我自己无法解决的新问题。我正在使用JQuery Datepicker创建一个日历，我可以选择日期范围。当我尝试将dateformat从默认值（mm/dd/yy）更改为dd.mm.yy时，它会失败并出现错误，并在我尝试选择任何日期时停止工作。另外，使用默认的dateformat不能使我的代码在加载时具有默认的选定日期。

这是我的代码，带有当前的datepicker设置（可以选择日期范围并使用其他类设置样式，还可以将从和到的日期放入隐藏的输入中和可见的div's），完整的样式在截图上看起来像：

datepicker范围工作：

希望你能帮我解决这个问题！

使用dateFormat: 'dd/mm/yy',并在解析日期时使用相同的格式来解析它。
