  Sure thing! Here's how you can use callback functions in jQuery to handle cryptocurrency price updates on your website: 1. First, you'll need to include the jQuery library in your HTML file. You can do this by adding the following code in the head section of your HTML file: <script src="https://code.jquery.com/jquery-3.5.1.min.js"></script> 2. Next, you'll need to write a function that fetches the cryptocurrency prices from an API. You can use the jQuery.ajax() function to make an HTTP request to the API and retrieve the data. 3. Once you have the data, you can update the prices on your website by manipulating the DOM using jQuery. You can use the jQuery.text() function to update the text content of an element with the new price. 4. To continuously update the prices in real-time, you can use the setInterval() function in JavaScript. This function allows you to execute a callback function at a specified interval. Inside the callback function, you can fetch the latest prices from the API and update the DOM. Here's an example code snippet that demonstrates how to use callback functions in jQuery to handle cryptocurrency price updates: <script> function fetchPrices() { $.ajax({ url: 'https://api.example.com/prices', success: function(data) { // Update the prices on the website $('.price').text(data.price); } }); } setInterval(fetchPrices, 5000); // Update prices every 5 seconds </script> Hope this helps! If you have any further questions, feel free to ask.
