  To create a live cryptocurrency price tracker using the on-change event in jQuery, you can follow these steps: 1. First, you need to fetch the cryptocurrency price data from a reliable API. There are several APIs available that provide real-time cryptocurrency price data, such as CoinGecko API or CoinMarketCap API. 2. Once you have the API data, you can use the jQuery on-change event to detect any changes in the selected cryptocurrency price. You can bind the on-change event to the input field or select dropdown that allows the user to select the cryptocurrency. 3. Inside the on-change event handler, you can make an AJAX request to the API and fetch the updated price data for the selected cryptocurrency. 4. After receiving the updated price data, you can update the price display on your webpage using jQuery's text() or html() function. 5. To make the live price tracker update at regular intervals, you can use the setInterval() function in JavaScript. Set the interval to the desired time duration, and inside the interval function, repeat the steps 2-4 to fetch and update the latest price data. By following these steps, you can create a live cryptocurrency price tracker that updates in real-time whenever there is a change in the cryptocurrency price.

  Creating a live cryptocurrency price tracker using the on-change event in jQuery is a great way to keep track of the latest prices. Here's a simple guide to help you get started: 1. Start by including the jQuery library in your HTML file. You can either download it and host it locally or use a CDN. 2. Next, create an HTML form with a select dropdown or an input field where users can select or enter the cryptocurrency they want to track. 3. Add an on-change event listener to the select dropdown or input field using jQuery's on() function. 4. Inside the event listener, make an AJAX request to a cryptocurrency price API of your choice. You can use the jQuery.ajax() function to send the request. 5. Parse the response data and extract the relevant price information for the selected cryptocurrency. 6. Update the price display on your webpage using jQuery's text() or html() function. 7. To make the tracker update in real-time, you can wrap steps 3-6 inside a setInterval() function. Set the interval to the desired time duration, and the tracker will automatically update at regular intervals. That's it! With these steps, you can create a live cryptocurrency price tracker using the on-change event in jQuery.
