jQuery and Ajax from Basic to Advanced + Practice Tests

Master jQuery and AJAX with selectors, DOM manipulation, events, effects, and asynchronous data loading.

This course is designed to take you from jQuery and AJAX basics to advanced front‑end development techniques, making it ideal for beginners as well as developers who want to enhance their client‑side scripting skills.

The course begins with an introduction to jQuery, explaining its purpose and how it simplifies JavaScript development. You will learn how to use jQuery selectors, including basic selectors, selector combinations, index and filter selectors, and form‑related selectors to efficiently access and manipulate HTML elements.

As you progress, the course covers DOM traversal techniques, helping you navigate elements within the document structure. You will then work with jQuery manipulation, where you will learn how to modify HTML content, dynamically add and remove nodes, and change styles at runtime.

The course also introduces jQuery effects, enabling you to enhance user experience with built‑in animations and visual transitions. You will then learn how to handle user interactions using jQuery events, making web pages interactive and responsive.

In the advanced section, the course focuses on AJAX, explaining how to communicate with servers asynchronously without reloading the page. You will work with AJAX fundamentals, the load method, GET requests, JSON data, and AJAX helper methods to build dynamic, data‑driven web applications.

A bonus lecture guides learners on what to learn next after completing the course. Practice tests are included to reinforce learning and validate your understanding.
