初始化2个datepickers非常慢

Question

I'm using the datepicker of Angular-UI .

I have a template that initializes 2 datepickers.

However, I noticed that it takes more than 100 ms on a desktop to initialize both.
It is worse than that using a two-years old mobile device.
I have the following declaration (2 times so):

<input type="text" ng-model="schedule.start" datepicker-popup date-disabled="disabled(date, mode)"/>

However, when I remove the datepickerPopup directive, it takes less than 100ms.

Is there a way a trick to increase performance of datepickerPopup directive?

Answer 1

There is a pull request here that wraps the date picker popup in an ng-if that should fix that. The performance hit comes from the DOM rendering all the calendar elements.
