How To Jquery And Javascript

Both JavaScript and jQuery are widely used in web development. This blog post will guide you through the basics of using both languages and help you understand how they can work together.

JavaScript Basics

JavaScript is a versatile, object-oriented programming language that is commonly used for client-side scripting in web development. It allows you to create interactive web pages and enhance user experience.

Adding JavaScript to your HTML file

JavaScript can be included in your HTML file by placing the code within <script> tags. You can place these tags either in the <head> section or at the end of the <body> section of your HTML file.

For example, to display an alert message when the web page loads, you can add the following code:

alert(‘Welcome to my website!’);

jQuery Basics

jQuery is a popular JavaScript library that simplifies many common tasks, such as DOM manipulation and event handling. It is lightweight and easy to use, making it a great choice for developers who want to improve their JavaScript skills.

Adding jQuery to your project

To start using jQuery, you need to include the library in your HTML file. You can either download it from the jQuery website or include it from a Content Delivery Network (CDN), like Google or jQuery’s own CDN. To include the library from the Google CDN, add the following code in the <head> section of your HTML file:

<script src=””></script>

jQuery Syntax

jQuery uses a simple syntax to select elements and perform actions on them. The basic syntax is:


For example, to hide all paragraphs on a page when a button is clicked, you can use the following code:

$(‘button’).click(function() {

Combining JavaScript and jQuery

Since jQuery is a JavaScript library, you can use both languages together in your web projects. Here’s an example of using JavaScript and jQuery together to create a simple web page that changes the color of a paragraph when a button is clicked:

<!DOCTYPE html>
<html lang=”en”>
<meta charset=”UTF-8″>
<meta name=”viewport” content=”width=device-width, initial-scale=1.0″>
<title>JavaScript and jQuery Example</title>
<script src=””></script>
<button id=”changeColor”>Change Color</button>
<p id=”demo”>This is a paragraph.</p>

$(‘#changeColor’).click(function() {
document.getElementById(‘demo’).style.color = ‘red’;

In this example, we use jQuery to handle the button click event and JavaScript to change the color of the paragraph. This demonstrates how both languages can work together to create interactive web pages.


JavaScript and jQuery are powerful tools for web development. By learning how to use both languages, you can create interactive, engaging web pages that provide a better user experience. We hope this blog post has given you a good starting point for using JavaScript and jQuery together in your projects.
