Example of using Models in Backbone JS

Models are data container where we can also add logics to data like validations, conversions or any specific computation if requires.

In this post we will understand how can we create our own Model Class and then create methods under it with data variables to contain the data.

Example:

Books Model Class

 var bookModel = Backback.Model.extend({});   

The above code will create a plain Model class of object bookModel. Now lets create some variables and set values into that.

 bookModel.set({bookName: "BackBone", noOfPages: 80});  

the above line will create 2 variables under bookModel Model Object.

To create a function under it, we can do while creating the Model class. For example:

 var bookModel = Backback.Model.extend({  
      publishBookPrice : function (){  
           alert("the price of this book is 200 INR");  
      }  
 });
