V0.3 Problems encountered.

[frehaiku]

When datePicker is opening, I click somewhere(without date itself).I want to hide.

But date field is dynamically change(used to createElement API).So If used parentNode API, you can't get document. At an early time, I think the date field how to bubble with document. Use delegates event feature?Use parentNode without null find uppermost layer element?

I read other code and find use parentNode is most common methods.For instance, freqdec/datePicker.
