Using jQuery for DHTML | DHTML

Welcome to the tutorial on using jQuery for Dynamic HTML (DHTML) development. jQuery is a popular JavaScript library that simplifies DOM manipulation, event handling, and AJAX interactions. In this tutorial, we will explore the basics of using jQuery, learn how to select and manipulate DOM elements, handle events, and make AJAX requests.

Introduction to jQuery

jQuery is a fast and concise JavaScript library that simplifies the process of interacting with HTML documents, handling events, creating animations, and making AJAX requests. It provides a wide range of functions and methods that can greatly enhance the development of DHTML applications. Let's get started with some basic examples:

Selecting DOM Elements

To select DOM elements using jQuery, you can use CSS-like selectors. Here's an example that selects all the paragraphs on a page:

This will return a jQuery object containing all the paragraph elements in the document. You can then perform operations on these elements, such as changing their content or applying styles.

Modifying DOM Elements

jQuery provides methods to modify DOM elements easily. For example, to change the text content of a paragraph element, you can use the text() method:

This will set the text content of all the paragraph elements to "Hello, world!".
