Fix “Position Fixed” in Phonegap IOS App

When I build a Phonegap App on IOS that has header and footer with “position fixed”. Everything works well on web version, and I start to test IOS app version, it seems work well too. But a problem orcurs when virtual keyboard opens and close, then the layout breaks (“position fixed”  of header and footer does not work). I took 2 hours to research and google. Finally, I work out a solution, it is quite simple. I just set “position static” for header footer when virtual keyboard close (input blur event) and set  a time out about 200 miliseconds to change back “position fixed”, the layout will be perfect again. The below is my code, you will be easy to understand it if you ever work with angularjs, coffeescript

When you use angularJS to build an app at client-side, a issue frequently orcur is datetime format.  My post will share with you the way that angularjs support you customize datetime format.

– Customize datetime format in controller (AngularJS):

Note: Please do not forget to inject $filter to your controller

– Customize datetime format in views (AngularJS):

Note: item_date is datetime with microsecond unixtimestamp format. E.g, 1288323623006

Actually, you can use raw javascript to customize your datetime format as the below way:

But my advice for you is if your project use AngularJS, you should not use raw javascript to cutomize datetime format, because in some cases, it will not work on Safari browser.

 

 

Cookies or LocalStorage Service in AngularJS

When you develop a web application, sometimes you need store data in client-side. In this case, you can use cookies or local storage. Some browsers do not support local storage (eg. IE 7,8), you should use cookies, but if you are building a phonegap application, local storage is unique choice.

The below code is coffee scripts, this is an anglarjs service that you can use to get, set or remove data from/to local storage.

And the below is an AngularJS service that will write data to cookies for the case the browser does not support local storage.
