Study Notes
jQuery Basics
- The primary purpose of jQuery is to simplify client-side scripting of HTML, making it easier to interact with and manipulate web pages.
- The jQuery method used to select elements is
$(), which is also known as the "selector" or "dollar sign" method. - The purpose of the
$(document).ready()function is to execute a block of code when the DOM (Document Object Model) is fully loaded, making it safe to interact with the page's elements. - The jQuery event method used to attach an event handler to an element is
.on(), which allows you to bind one or more event handlers to a specific element. - The purpose of the jQuery Ajax method is to perform asynchronous HTTP requests, enabling you to fetch data from a server without requiring a full page reload, and update the page dynamically.
Test your knowledge of jQuery fundamentals, including selecting elements, event handling, and Ajax methods.
