Backbone.emulateHTTP()

Backbone.emulateHTTP is used when you want to work with a legacy web server that doesn't support Backbone's default REST/HTTP approach. If you set this option to true, it will fake PUT, PATCH and DELETE requests with a HTTP POST, setting the X-HTTP-Method-Override header with the true method.

Syntax:

Let's take an example.

See this example:

<!DOCTYPE html>
   <head>
      <title>emulateHTTP Example</title>
         <script src="https://code.jquery.com/jquery-2.1.3.min.js" type="text/javascript"></script>
         <script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.2/underscore-min.js" type="text/javascript"></script>
         <script src="https://cdnjs.cloudflare.com/ajax/libs/backbone.js/1.1.2/backbone-min.js" type="text/javascript"></script>
   </head>
   <body>
      <script type="text/javascript">
         Backbone.emulateHTTP = true;
         Backbone.sync = function(method, model) {
            document.write(method + ": " + JSON.stringify(model));
            model.set('id', 1);   
         };
         var Boxer = new Backbone.Model({
            firstname:"Vijender",
            lastname:"Singh"
         });
        Boxer.save();
         Boxer.save({country: "india"});
      </script>
   </body>
</html>
