  Sure! To use jQuery onchange to update cryptocurrency prices in real-time, you can follow these steps: 1. First, make sure you have included the jQuery library in your HTML file. 2. Create a select element in your HTML code to allow users to choose the cryptocurrency they want to display the price for. 3. Add an onchange event to the select element, which will trigger a JavaScript function whenever the user selects a different cryptocurrency. 4. In the JavaScript function, use AJAX to send a request to a cryptocurrency price API, such as CoinGecko or CoinMarketCap, to fetch the latest price data for the selected cryptocurrency. 5. Once you receive the response from the API, update the price display on your website using jQuery's text() or html() function. Here's an example code snippet: ```html <select id="cryptocurrency"> <option value="bitcoin">Bitcoin</option> <option value="ethereum">Ethereum</option> <option value="ripple">Ripple</option> </select> <div id="price"></div> <script> $(document).ready(function() { $('#cryptocurrency').on('change', function() { var selectedCryptocurrency = $(this).val(); $.ajax({ url: 'https://api.coingecko.com/api/v3/simple/price?ids=' + selectedCryptocurrency + '&vs_currencies=usd', method: 'GET', success: function(response) { var price = response[selectedCryptocurrency].usd; $('#price').text('$' + price); } }); }); }); </script> ``` This code will update the price display whenever the user selects a different cryptocurrency from the dropdown menu.
