Newbie questions about Sencha Touch

[bagusflyer]

I'm new to Sencha Touch. I'm going to develop a web app in Sencha Touch. Here is the short description:

- My application will retrieve data from MySql database and also need to save data to database.
- There are about 10 different pages.

My questions is:

- Do I have to use Json to get data from my database? I have now way to integrate Sencha Touch with php to get data directly from php, right?
- Do I have to create different pages or just different panels? If I create different pages, is it possible to use transition animation to transit from one page to another one?

Thanks for advance.

So in your Ext.data.Store, when it loads data, it loads it from a PHP script. You can use JSON or XML as a transfer between PHP and Sencha Touch with JSON being the very much preferred transport means. PHP has a native way to endcode/decode JSON with json_encode(array(...)) and json_decode('...').

Sencha Touch is best used as a single page application. You cannot do transitions between different pages and you would have to redownload the JS and CSS files for each page which would not be a good user experience. So adding and removing panels with transitions is the best practice.

OK, I see. Then I can use multiple views in different js files. But here comes another question is there a way to load js file dynamically? For example, I have 10 views in my application, I'll write 10 js files for them, I only load views according to certain condition, some views are even not needed at all if the user won't select them. If I load all the views it's a waste of bandwidth.

Yes version 2 of Sencha Touch is much better at loading these view dynamically.....it is possible in v1 although you would have to follow a tutorial such as this one:
