Backbone.js is a compact library used to organize JavaScript code. An MVC/MV* framework is another term for it. If MVC is unfamiliar to you, it is just a technique for designing user interfaces. The creation of a program’s user interface is made considerably easier by JavaScript functions. BackboneJS provides a variety of building elements to aid developers in creating client-side web applications, including models, views, events, routers, and collections.

Sync’s emulateJSON is mainly used in the cases where the web server cannot handle encoded application/JSON requests. This method is mainly useful in the case of using a legacy web server. The activity of this method is to serialize the JSON under a model and process it as if it is an HTML form.

Syntax:

Backbone.emulateJSON=true

Example 1: The code below demonstrates syncing of a collection and how we can use the emulateJSON() method, so we can easily serialize the JSON under the model.

HTML




<!DOCTYPE html>
<html>
  
<head>
    <title>Backbone.js Sync emulateJSON</title>
    <script src=
 "https://code.jquery.com/jquery-2.1.3.min.js" type="text/javascript">

</head>
  
<body>
    <h1 style="color: green;">
        GeeksforGeeks
    </h1>
  
    <h3>Backbone.js Sync emulateJSON</h3>
  
    <script type="text/javascript">
        Backbone.emulateJSON = true;
        var newCol = new Backbone.Collection({
            title: "GeeksforGeeks",
            about: "A computer science portal for Geeks!!"
        });
  
        Backbone.sync = function (method, model) {
            document.write("The state of the Collection:");
            document.write("<br>");
  
            document.write(method + ": " + JSON.stringify(model));
        };
  
        newCol.fetch();  
    </script>
</body>
  
</html>
