Introduction to jQuery Training (JQY111)

This course offers a deep dive into jQuery, a popular JavaScript library that simplifies HTML DOM manipulation, event handling, and Ajax interactions. Although JavaScript frameworks and libraries have evolved, jQuery remains relevant, especially for maintaining and upgrading legacy code. This course is ideal for developers looking to understand or revisit jQuery in the context of modern web development.

The course begins with an introduction to jQuery, addressing its relevance in the 2020s and outlining the approach you'll take throughout the lessons. You'll start by setting up Bootstrap and reviewing basic JavaScript code to establish a foundation. Then, you'll get hands-on experience with jQuery, including exercises to familiarize yourself with its syntax and features.

The jQuery Function and Selectors section delves into how jQuery interacts with the DOM. You'll learn about the document ready event, waiting for the load event, and using jQuery selectors to target elements. The section covers filtering, tree traversal, and caching jQuery objects, with practical exercises on playing with selectors, chaining methods, and using utility functions.

In the jQuery Manipulation module, you'll explore getter and setter methods for manipulating DOM elements. You'll practice setting, adding, copying, and removing content on web pages. The course includes a comprehensive exercise series where you'll build a shopping list application, learning how to handle events, manage attributes, and prevent common issues like duplicates and empty inputs.

Next, the jQuery Forms and Events section teaches you how to listen for, trigger, and delegate events. Event delegation is a powerful technique that you'll practice through exercises, enabling you to manage events efficiently in dynamic web applications.

The jQuery Effects module covers various visual effects, including display, fading, and sliding effects, as well as other animations. You'll learn to create engaging user experiences by applying these effects and managing their timing and sequencing.

The Ajax and jQuery section introduces you to Ajax, a technique for asynchronously updating web pages. You'll learn to use jQuery's Ajax methods for tasks like form validation, with exercises to solidify your understanding of how Ajax integrates with jQuery.

The course also covers the process of converting code between jQuery and vanilla JavaScript. You'll explore the reasons for converting jQuery to JavaScript, and vice versa, along with exercises that guide you through converting common functions, configuration views, and game views. This dual approach ensures you understand the strengths and limitations of both jQuery and JavaScript.

The final module includes a review of the "Mathificent" jQuery code, providing an opportunity to apply everything you've learned in a comprehensive review of real-world jQuery code.

By the end of this course, you'll have a solid grasp of jQuery, its applications, and how to integrate it effectively into both legacy and modern web development projects. You'll also gain the skills to convert between jQuery and JavaScript, making you a more versatile and capable developer.
