I'm trying to use Extjs4 MVC to achieve a manager system.So I need a Login page and system Index page.After login success,the page will jump to the index.html(The system main menu) .And If my Login page starting with Ext.application,and the index page also starting with Ext.application? How can I design the system with MVC mode?Can you give some suggestions?Thanks a lots!
Web apps based on ExtJS4 are supposed to be single browser page(.html/.php). In your case you can use a card layout which will help you to switch between pages(cards on same .html) based on some conditions, and you will have one workspace/Ext.application
the same approach described above, with card layout. If you have a large application then you split it up in subapplications, each subapp providing a specific similar or related group of functionalities, this is more complicated, but is achievable.
