JavaScript MVC 2.3 - Understanding a real AngularJS App-ViewModel

This is a part of my second short series about JavaScript MVC Frameworks. In this part I'll show you a real-life AngularJS App (albeit a simple one) and explain all relevant parts so that you can create your own. I've split it into multiple posts - this one explains all the angular magic in the Model or ViewModel - also called the $scope - while the other posts focus on the View, Controller and more.

If you have not already read the previous parts, I would highly recommend you start there. Especially the post about the AngularJS App-View contains vital information + prerequisites so you can try all this code directly in your DNN.


To learn AngularJS you will have to get your hands dirty. So go ahead and install DNN with 2sxc as explained in this post  and install this demo-App containing all the code explained here.

Continuing with the ViewModel AKA the Model AKA the $scope

Our ViewModel / Model / $scope looks like this

  • $scope
    • moduleId
    • header (the header object)
      • Title
      • Content
      • SafeContent
      • EntityId
      • Toolbar (the HTML containing the hover-buttons)
      • + some background infos about the Entity which 2sxc needs for edit-buttons
    • list {} (the items in the content as an array)
      • [0] (the first item)
        • Question
        • Category
        • Answer
        • SafeAnswer (html-safe answer)
        • Link
        • Toolbar
        • + some background infos for editing etc.
        • showDetails (automatically created when clicking on the title to show details)
      • [1…] (next items, same structure)

This is all assembled in the controller, here

Just to be more specific

  1. The blue marked code creates the header-structure. Because the item in[0] already has a Title, EntityId and Content, they don't need extra coding - this was already delivered like this from the JSON
  2. the green section adds the items. Again many properties already exist, including Question, Answer and more.
  3. The pink marked sections ensure that we can do HTML-Binding for this information.

Summing it up!

This is all very straight forward - just try it yourself - add fields, see how you can use them.
So that's it for the ViewModel/Model/$scope.

You must get your hands dirty!

Reading this won't make you smarter if you don't try it yourself. Just use 30 minutes to download the App, make some adjustments (like adding fields or changing the JS-effects). That way you'll get smart really fast!
