Hi everyone, welcome to today’s exciting read, where you’ll learn how to use jQuery!
Today, we will walk you through all there is to know about the jQuery function and library.
At the end of this read, we promise you will walk away with a fuller knowledge of what jQuery is, its usage, and why it is a better option for Web Developers.
In this article we covered:
- What is jQuery?
- jQuery usage
- Free and paid resources for jQuery
- Future outlook of the library
Let’s get started!
What is jQuery and How it Works?
The three most important web languages are CSS, HTML, and JavaScript.
We use HTML to structure our web pages, JavaScript to offer interactive features, and CSS to style them.
In reality, JavaScript is used to create most animations and any activity that occurs as a result of a user hovering, clicking, or scrolling.
jQuery is a quick, compact JavaScript framework that makes it easier to traverse HTML documents, execute animations, handle events, and add Ajax interactions to your websites.
jQuery was created to revolutionize the way you write JavaScript.
The “Write Less, Do More” JavaScript library is jQuery.
It is not a programming language, but rather a tool for condensing the writing of typical JavaScript jobs.
jQuery also has the advantage of being cross-browser compatible, which means that the output of your jQuery code will look exactly as you meant it to in any modern browser.
To put it another way, jQuery reduces ten lines of typical Javascript code to just two!
When you combine a large number of features with cross-platform compatibility, you get a solid framework.
You’ll be developing everything from complex forms to Flash-like menus before you realize it.
Don’t be worried if the prospect of learning another framework appears daunting.
The materials listed in this article will guide you through the process.
Using jQuery
You should be interested to know how to use jQuery if you are on this page! Let’s get going:
Stage 1: Downloading Jquery Library
Downloading the library will be the first step in your trip.
Scroll down to the “Download jQuery file” section on jQuery.com.
The library will be downloaded to your computer if you select one of the provided links.
Be sure to also import the.js file into your solution.
There are two methods for incorporating jQuery into a project:
- Link to a file via Content Delivery Network (CDN)
- Download a local copy
Stage 2: Create Your First Function
Naturally, you should be developing functions in five minutes after learning jQuery.
You can practice by making a simple Web Development project.
Style.css should be in the CSS/ directory, script src should be in the js/ directory, and the main index.html will be in the project’s root directory.
The introductory tutorial “How jQuery Works” by John Resig should be your first stop.
There he demonstrates a variety of simple methods for adding and removing classes, chaining, and calling the “document.ready” method in your web apps.
Stage 3: Bring Your Elements to Life
For many coders, this is a contentious issue.
There are those in group one who insist on “zero animation.”
They allow users to get what they need as quickly as possible and then send them on their way.
However, there are persons in group number two.
They consider a site with some well-executed animation to be one worthy of their user base.
They feel that when applied appropriately, animation can considerably increase usability.
You’ll have to figure out which one you are for yourself.
Stage 4: Plugins
The great thing about jQuery is that when it was first created, John Resig and his team made sure that adding functionality through the usage of plugins could be done with only a few lines of code.
We can implement particular plugins only when needed by keeping these plugins distinct from the core library (which is only 16kb).
As a result, the size of your javascript files will be reduced as much as feasible.
Stage 5: AJAX Functionality Implementation
Do you have faith in your jQuery abilities yet?
Are you prepared to take your business to the next level?
Why don’t you start incorporating Ajax functionality into your scripts?
jQuery makes loading data extremely simple by using the “load()” and “.get()” functions.
How Do I Run a jQuery Script?
jQuery’s main role is to use the DOM to connect with Html files in the web browser.
The DOM (Document Object Model) is the interface between the HTML in a browser and JavaScript.
Right-click on the present web page in your HTML browser and pick ‘Inspect’ to have a detailed view of the DOM.
The HTML page will be launched as a result of this step.
The HTML code you see here is the DOM.
Every HTML element is a node (node.js) in the DOM, this indicates it’s an object that JavaScript can relate with.
Each nested component is a branch further down the growth, with html> being closer to the root.
JavaScript can be used by Developers to remove, change, or add to any of these items.
If you right-click the website again and choose ‘View Page Source’, you’ll view the website’s raw output of the HTML.
It’s uncomplicated to mix up the HTML source with the DOM at first, even though they’re not similar: the web page source is precisely what’s coded into the HTML file.
It is dormant and cannot be altered, and JavaScript will have no influence on it.
Nonetheless, the DOM is subject to change and dynamics.
What a jQuery Syntax Looks Like
<!doctype html>
<html lang=”en”>
<head>
<title>jQuery Demo</title>
<link rel=”stylesheet” href=”css/style.css”>
</head>
<body>
<script src=”https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js”></script>
<script src=”js/scripts.js”></script>
<div class=”container”>
<div class=”item”>Item 1</div>
<div class=”item”>Item 2</div>
</div>
</body>
$(document)
//Or
$(window.document)
//Or
jQuery(document)
//Or
window.jQuery(document)
</html>
Best Free Resources for Jquery
These Udemy and Pluralsight free jQuery classes are actually quite good and comparable to many other premium ones.
They’re usually given away for free to promote or educate people.

Why Use JQuery Library?
Naturally, as a Developer, you would wonder why you should use jQuery library over others.
In the end, it comes down to personal preference.
Every framework has its own set of benefits.
However, there is a reason why jQuery is the most widely used framework.
Here are some features of jQuery that made it preferable:
Cross-Browser Compatibility
A Web Developer can expect to spend a significant amount of time correcting each browser’s peculiarities while using Javascript.
Fortunately, the jQuery library eliminates these inconsistencies in browsers, giving Developers more time to work on their code.
CSS Selectors
Developers can leverage their existing knowledge to navigate their documents by using CSS syntax.
jQuery provides a fantastic tool for controlling the elements on your page, thanks to the integration of several XPATH and CSS 3 selectors.
Chaining
For its techniques, jQuery employs a technique known as “chaining.”
When you call a method on a jQuery object, the method returns the identical jQuery object every time.
You won’t have to retype your selectors for each method as a result.
Future Prospects of Jquery
Unfortunately, the popularity of JQuery has been waning for some time.
JQuery is anticipated to become obsolete soon enough due to JavaScript’s ubiquitous and consistent browser support.
Many web Developers currently choose easier-to-use tools or frameworks, such as React, Angular, or Vue.
Conclusion
JQuery is widely utilized in the Web Development business, with thousands of well-known applications.
As a result, learning and mastering it is critical if you want to continue to advance as a Web Developer.
After you’ve learned HTML, CSS, and JavaScript, it’s natural to move on to JQuery.
This is due to a number of factors.
Learning the language before the framework will give you a better understanding of what the framework does.
You’ll also be better able to use JQuery creatively because you’ll have a better knowledge of the issues it was created to address.
Hopefully, you now have a better knowledge of JQuery’s purpose and many advantages.
