JSON is a standard and is specified on RFC4627 on IETF (International Engineering Task Force). Because of the very nature of the JSON, it is useful for storing or representing semi structured data In computer science, serialization is a process to transforming data structures and objects in a format suitable to be stored in a file or memory buffer or transmitted over a network connection. JSON is often used to serialize and transfer data over a network connection, for example between the web server and a web application. It is entirely language independent and can be used with most of the modern programming languages. JSON is derived from a subset of JavaScript programming language (Standard ECMA-262 3rd Edition-December 1999). JSON is a lightweight text-based open standard data-interchange format. The following visual representation from Google Trend may help you to understand the how JSON is gaining popularity over years. May be that is why JSON has got wide acceptance from the developer community. Moreover, any modern programming language can work with JSON. In fact, if you are familiar with any of the modern day programming language (e.g PHP, JavaScript, Ruby) you are already familiar with the data structures used in JSON. Ultimately, JSON is used as a data model, but compared to other data models like Relational Database or XML, it has a low learning curve. The document ends with a list of what you will learn in other tutorials of this series, which is sort of a roadmap of basic things you need to learn for working with JSON and a summary of the points discussed. This tutorial begins a set of tutorials on JSON and discusses definition, specification, What JSON looks like in real world, a bit of History of JSON, comparison between Relational Database and JSON, a brief understanding of when to elect JSON over Relational Database, XML vs JSON, Syntax of JSON, typical examples of real world uses of JSON. As a web developer, you will find plenty of occassion when you will require applying or working with JSON in your project. So while posting json data using jquery ajax in MVC we can get the objects in the action method without the need to manually map the posted values.This is an introductory tutorial on JSON - JavaScript Object Notation. We are passing the following parameter to the UpdateEmployees action method which we are calling using the ajax() methodĪfter the action method is called the empLst parameter will contain the list of employee objects which we had passed using json. Public ActionResult UpdateEmployees(List empLst) We have defined the controller as: public class EmployeesController : Controller In the button click method we are calling the Update() method. In the view we are creating an html table having multiple rows.Each row has different cells corresponding to the Employee class properties such as Name,Address and Phone number. We will be sending the following object using json from the view to the action method.

The action method parameter will be populated with the posted JSON objects ,using the built in model binding.Once we have the collection of objects in the action method we can perform an operation on it such as saving in the database. In the following example user will be entering data in a html table.The data will posted to the action method in the JSON format.

JSON is a data exchange format which is commonly used to exchange the data between the web server and the web browser.In Fetching json data using jquery ajax in MVC we looked at how to fetch data using JSON from the MVC controller.Now we will see how to pass data in JSON format from the web browser to the controller action method.
