Implementing a JSON Model

The JSON model can be used to bind controls to JavaScript object data, which is usually serialized in the JSON format. The JSON model is a client-side model and, therefore, intended for small datasets, which are completely available on the client. The JSON model does not support mechanisms for server-based paging or loading of deltas. It supports, however, two-way binding.

1. To create a JSON model instance, insert the following code:

   var oModel = new sap.ui.model.json.JSONModel();

2. After the instance has been created, there are different options to get the data into the model.
   • The easiest option is to set data by using the setData method:

     oModel.setData({
         firstName: "Peter",
         lastName: "Pan"
     });

     Note The correct JSON notation uses double quotes for the keys and string values.
   • Usually, you do not define your data inline in the application but load it from a server-side service using an XHR request. The JSON model, however, also has a loadData method, which loads the JSON data from the specified URL asynchronously and applies it to the model:

     oModel.loadData("data.json");
