The major purpose of jQuery is to make it easy for the developers to use Javascript for software development and other tasks. In this blog, we will learn more about jQuery and this jQuery tutorials will be most beneficial for beginners who are just starting with this Javascript library.
What is jQuery?
jQuery is a featured rich javascript library which simplifies various common tasks of javascript such as HTML document traversal, event handling, animation, and more which ultimately helps in faster web development. With jQuery you will need to write less code and it is also very easy to learn.
This library reduces the complex lengthy code of javascript and makes it more readable and simple. With jQuery our approach in writing the Javascript code has completely changed as it helps in saving time and resources both. jQuery tutorials for beginner is a simple article covered to help beginners become familiar with all possibilities using jQuery.
jQuery Tutorials: Key Takeaways
- jQuery is a javascript library used to optimise Javascript complex code, HTML document traversal, animation, and Ajax.
- JQuery is an open source and free javascript library mainly used for writing small and maintainable javascript code.
- JQuery was first launched in 2006 by John Resig and is one of the most popular javascript libraries currently.
The History Of jQuery Library
jQuery was released by John Resig at BarCamp New York in 2006. It provided a simpler way to handle the DOM manipulation, events and Ajax. The complex code of javascript is simplified after the introduction of jQuery. It provided easy syntax and enabled powerful animation, Ajax and event handling.
Soon after its release in 2007 jQuery gained popularity due to its simplicity and cross browser support. Major companies like Microsoft, Noika announced support for jQuery in 2008 and became one of the most popular libraries of Javascript in use. JQuery introduced mobile support to enable cross device development. Let us get familiar with the important features of jQuery library in this jQuery tutorials.
How to Implement jQuery in Web Development Projects
In this jQuery tutorials we will also learn how to implement or add jQuery in our HTML document.
- You can import jQuery in your project with CDN which you can easily paste in your HTML document <head> part or before closing the <body> tag.
| <script src=”https://code.jquery.com/jquery-3.6.0.min.js”></script> |
- You can get this CDN from the official page of jQuery on the internet. Just search for jQuery CDN and click on the first website.
- You can also download the host file locally on your system from the jQuery website. Save it using “jquery.min.js” in your project folder.
- Now when you have embedded the jQuery library in your project you can start coding inside the <script> tag. You have to use the following function code to start.
| $(document).ready() |
- Let us take an example to understand the following syntax.
| <script>
$(document).ready(function(){ // jQuery code here }); </script> |
- You have to insert the code inside the function which you want to execute. The code runs after the page is fully loaded on the server.
In these java tutorials for beginners this was just a simple overview of how to embed jQuery in your web development project. You can try yourself once by following the above steps.
jQuery Tutorials: Simple Example For Beginners
There are a variety of Javascript tasks that you can easily implement using jQuery such as animation, DOM manipulation, Ajax, and more. In Real projects jQuery is used for form validation, dynamic content loading using Ajax, responsive navigation, UI interactions, and much more. Let us take a simple example to understand this framework in this jQuery tutorials.
| <!DOCTYPE html>
<html> <head> <script src=”https://code.jquery.com/jquery-3.6.0.min.js”></script> <script> $(document).ready(function(){ $(“#btn”).click(function(){ $(“#message”).text(“Hello from jQuery!”); }); }); </script> </head> <body> <button id=”btn”>Click Me</button> <p id=”message”></p> </body> </html> |
In the above code we have embedded jQuery in the <head> section of HTML document. Now, inside the <script> tag we will mention the functionality we need for our HTML elements.
Here, we have defined the functionality of a button when we perform a click operation i,e. It will display a message “Hello from jQuery!” in the <p> element. We will delve into the deeper concept of jQuery in advanced jQuery blogs.
