What Is jQuery?
One of the popular extensions to jQuery is jQuery UI. It contains a curated set of widgets, animations, themes, and other UI elements. To improve jQuery functionality for your particular website, you can choose from a wide range of plugins that add everything from social media chat support to video players.
What Is jQuery Used For?
These core features include HTML DOM tree traversal, event handling, AJAX methods, CSS manipulation, etc. You can use it for simple stuff like implementing a button that gets highlighted when you hover your cursor over it. Or you can design an entire menu system for your website (maybe even throw in a plugin that adds autocomplete for the search bar).
One of the most common uses for jQuery is connecting and manipulating HTML elements using the DOM (Document Object Model). This lets you access hundreds of individual HTML elements simultaneously without addressing each one on its own. Plus, you can easily make animations with the built-in methods.
Is jQuery Frontend Or Backend?
Before we get started, I need to clarify what frontend and backend even mean from a developmental standpoint. In layman’s terms, frontend refers to all the “client-side” stuff that you see in your browser. Namely, the UI and other stuff that you directly interact with from your side.
Backend refers to all the “server-side” processes that exist to facilitate the smooth functioning of the frontend. It’s like backstage at a concert or show- you don’t see it, but there’s some really important stuff going on behind the scenes. Think databases, algorithms, etc.
5 jQuery Features That Make Coding Easier
Dom Traversal And Manipulation
In order to do this, we need a table of some sort that documents all of the HTML elements within a page. Whenever your browser loads a webpage, it creates a Document Object Model that’s structured like a tree with various nodes. Nodes are ordered via a hierarchical system (parent, child, sibling, etc.), and represent various things like links, paragraphs, etc.
Simplified Event Handling
CSS And Animations Are Easier To Implement
CSS is a design language that’s essential for “styling” your HTML page with fonts, colors, formats, layouts, etc. And with jQuery, you can easily do DOM traversal using CSS selectors. With jQuery, dynamically styling elements is easy, and it even contains built-in animation methods that let you define CSS properties (or add effects).
Contains Several AJAX Methods For Backend Purposes
Beginner’s Guide To Learning And Using jQuery
There are nearly infinite resources available for free on the internet. You can check out sites such as w3schools and Tutorialspoint. But before you get started with these, I highly recommend you learn some CSS and HTML first.
I hope this article gave you some insight into what jQuery is and how it’s used to simplify web development. If you’re gearing up to be a frontend web developer, jQuery is definitely one of the tools you’ll want in your arsenal. Even if newer projects don’t make extensive use of it, you’ll often have to do legacy work or maintain existing sites that use jQuery.
There are plenty of extensions, plugins, etc. available for jQuery that extend its capabilities. It’s completely open-source and freely distributed under the MIT license. Both designers and programmers can benefit from understanding how jQuery works.
