Create an "Add to cart" button in Bootstrap
Bootstrap is a popular front−end framework that makes it easier to design and develop responsive and mobile−first websites. It provides several components and plugins that can be used to create an add−to−cart button and implement this functionality on a website. It contains pre−built styles and functionality that can save time and effort .
Algorithm
Load the necessary libraries and files using Content Delivery Network (CDN).
Define the HTML structure of the page, including the product image, name, description, price, and "Add to Cart" button.
Define the modal window structure that will appear when the "Add to Cart" button is clicked.
Define the Javascript functionality that will trigger the modal window to appear when the "Add to Cart" button is clicked.
When the page is loaded, wait for the "Add to Cart" button to be clicked.
When the "Add to Cart" button is clicked, show the modal window with the message "The product has been added to your cart."
When the modal window is displayed, allow the user to click the "Close" button to dismiss it.
Example
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<!-- Link to the Bootstrap CSS file hosted on a content delivery network (CDN) -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css">
<!-- Link to the jQuery library hosted on a CDN -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.3/jquery.min.js"></script>
<!-- Link to the Bootstrap JavaScript file hosted on a CDN -->
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script>
<title>Add to Cart</title>
</head>
<body>
<!-- Modal window that will appear when "Add to Cart" button is clicked -->
<div class="modal fade" id="myModal">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<!-- Title of the modal window -->
<h4 class="modal-title">Added to cart</h4>
<!-- Close button to dismiss the modal window -->
<button type="button" class="close" data-dismiss="modal">×</button>
</div>
<div class="modal-body">
<!-- Text displayed in the body of the modal window to confirm that the product has been added to the cart -->
The product has been added to your cart.
</div>
<div class="modal-footer">
<!-- Button to close the modal window -->
<button type="button" class="Close" class="btn btn-secondary" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
<!-- Product information displayed on the webpage -->
<div class="container">
<div class="row">
<div class="col-md-6">
<!-- Image of the product -->
<img src="https://www.tutorialspoint.com/bootstrap/images/tutimg.png" class="img-fluid">
</div>
<div class="col-md-6">
<!-- Name of the product -->
<h2>Product Name</h2>
<!-- Description of the product -->
<p>Description of the product</p>
<!-- Price of the product -->
<h4>$19.99</h4>
<!-- Button to add the product to the cart -->
<button class="btn btn-primary add-to-cart">
<i class="fa fa-shopping-cart"></i> Add to cart
</button>
</div>
</div>
</div>
<!-- Javascript functionality -->
<script>
$(document).ready(function(){
// When the "Add to Cart" button is clicked, display the modal window
$(".add-to-cart").click(function(){
$("#myModal").modal();
});
});
</script>
</body>
</html>
The use of Bootstrap and jQuery libraries makes it easy to implement and customize the modal window.
This code uses the jQuery library to add functionality to the modal window, such as displaying it when the "Add to Cart" button is clicked.
Conclusion
This code relies on external Bootstrap CSS and JavaScript files hosted on a content delivery network (CDN). If the CDN is unavailable or experiences downtime, it may affect the functionality of the code. Instead of relying on external libraries hosted on CDNs, the code could include local copies of the libraries to improve security. Bootstrap is compatible with most modern web browsers, but some older browsers may not support all features of the framework. In addition, Bootstrap CSS and JavaScript files can be quite large, which can slow down the loading time of the webpage.
