Web Development With jQuery, Ajax and JSON Certification – The Digital Adda
Web development with jQuery, Ajax, and JSON is a powerful combination that allows you to create dynamic and interactive web applications. Here’s a brief overview of each technology and how they work together:
jQuery: jQuery is a popular JavaScript library that simplifies HTML document traversal, event handling, animation, and provides an easy-to-use API for interacting with the Document Object Model (DOM). It provides a wide range of utility functions and simplifies common tasks, making it easier to manipulate and interact with web page elements.
Ajax: (Asynchronous JavaScript and XML): Ajax is a technique that allows you to send and receive data from a web server asynchronously without interfering with the user’s interaction on the web page. It enables you to update parts of a web page without refreshing the entire page. With Ajax, you can send HTTP requests in the background and handle the responses dynamically, typically using JavaScript.
JSON (JavaScript Object Notation): JSON is a lightweight data interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is based on a subset of JavaScript syntax and is often used for transmitting data between a server and a web application. JSON data is represented as key-value pairs and supports nested structures, making it ideal for structuring and transferring data.
