  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.
