Welcome to our comprehensive guide on creating a Star Rating system using jQuery! In this tutorial, we will walk you through the process step-by-step, starting from the basics and moving on to advanced techniques.
By the end of this tutorial, you will have a solid understanding of how to create and implement a functional star rating system in your projects. Let's get started!
A star rating system is a common user interface element used to allow users to rate items or services. It's simple, intuitive, and versatile, making it a popular choice for various applications.
In this tutorial, we will build a basic star rating system with jQuery that allows users to select a rating from 1 to 5 stars.
First, let's create a simple HTML structure for our star rating system:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Star Rating with jQuery</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<div id="star-rating"></div>
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script src="script.js"></script>
</body>
</html>In this example, we have a div with the id star-rating where our star rating system will be displayed.
Now, let's create the JavaScript (jQuery) code for our star rating system:
$(document).ready(function() {
var stars = Array.from(document.getElementsByClassName('star'));
var currentRating = 0;
stars.forEach(function(star, index) {
star.addEventListener('click', function() {
// Reset the rating for all stars
stars.forEach(function(star) {
star.classList.remove('filled');
});
// Fill up the clicked star and the ones to its right
for (let i = index; i >= index - currentRating && i <= index + currentRating; i--) {
if (i >= 0) {
stars[i].classList.add('filled');
}
}
currentRating = index + 1;
});
});
});In the above code, we've selected all the stars using jQuery and added an event listener for the click event. When a star is clicked, we first reset the rating by removing the filled class from all stars. Then, we fill up the clicked star and the ones to its right, updating the currentRating variable.
To style our star rating system, we'll create a separate CSS file named styles.css:
.star {
font-size: 30px;
color: #cccccc;
cursor: pointer;
}
.star.filled {
color: #ffd700;
}Here, we have defined the basic style for our stars and added a filled class to style the filled stars with a yellow color.
Now, let's test our star rating system by saving the HTML, JavaScript, and CSS files in the same directory and opening the HTML file in a web browser. You should see a clickable star rating system, just like the one below:

Clicking on the stars will allow you to select a rating, demonstrating the functionality of our star rating system using jQuery.
What is the purpose of the click event listener in the jQuery code?
What does the `stars.forEach` function do in the jQuery code?
What does the `currentRating` variable keep track of in the jQuery code?
With this tutorial, you now have the knowledge and skills to create a functional star rating system using jQuery. We encourage you to experiment with the code and customize it to suit your needs. Happy coding! š
