Action Context¶

The Action Context is an essential element of the Mojito framework that gives you access to the frameworks features from within a controller function. To use the Action Context, you create an instance of the ActionContext class, which we will call ac for short. From ac, you can call methods to execute mojit actions within either a server or client context. See the ActionContext Class for the methods available from ac.

One of the most common methods used from an instance of the ActionContext class is done, which lets you pass data from the controller to a view. In the example controller.server.js below, the done method sends the data object to the index template.

YUI.add('HelloMojit', function(Y, NAME) {
  /**
  * The HelloMojit module.
  *
  * @module HelloMojit
  */
  /**
  * Constructor for the Controller class.
  *
  * @class Controller
  * @constructor
  */
  Y.namespace('mojito.controllers')[NAME] = {
    init: function(config) {
      this.config = config;
    },
    /**
    * Method corresponding to the 'index' action.
    *
    * @param ac {Object} The action context that
    * provides access to the Mojito API.
    */
    index: function(ac) {
      var data = { "data":"data passed to the index template" };
      ac.done(data);
    }
  };
