This appendix covers
- Removing the data from all views, except the homepage
- Moving the data into the controllers
Chapter 4 covers setting up the controllers and the views for the static, clickable prototype. The “how” and “why” are covered in that chapter in more detail, so this appendix will really focus on what the end results should be.
Part of this includes moving the data back down the MVC flow from the views into the controllers. The example in chapter 4 deals with this in the Loc8r homepage, but it needs to be done for the other pages too. We’ll start with the Details page.
The Details page is the largest and most complex of the pages, with the most data requirements, but following the homepage is the most logical place for it to go. The first step is setting up the controller.
The controller for this page is called locationInfo in the locations.js file in app_server/controllers. When you’ve analyzed the data in the view, and collated it into a JavaScript object, your controller will look something like the following listing.
A part to note here is the latitude and longitude being sent through. You can get your current latitude and longitude from this website: http://www.where-am-i.net/.
