我正在創建一個閱讀更多按鈕，但我的意圖是當它被點擊時，它應該顯示一條彈出消息，說明已成功付款，然后顯示該段落的其余部分。這是我的代碼function myFunction() { var dots = document.getElementById("dots"); var moreText = document.getElementById("more"); var btnText = document.getElementById("myBtn"); if (dots.style.display === "none") { dots.style.display = "inline"; btnText.innerHTML = "Read more"; moreText.style.display = "none"; } else { dots.style.display = "none"; btnText.innerHTML = "Read less"; moreText.style.display = "inline"; }}<!DOCTYPE html><html><head> <meta name="viewport" content="width=device-width, initial-scale=1"> <style> #more { display: none; } </style></head><body> <h2>Read More Read Less Button</h2> <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus imperdiet, nulla et dictum interdum, nisi lorem egestas vitae scel<span id="dots">...</span><span id="more">erisque enim ligula venenatis dolor. Maecenas nisl est, ultrices nec congue eget, auctor vitae massa. Fusce luctus vestibulum augue ut aliquet. Nunc sagittis dictum nisi, sed ullamcorper ipsum dignissim ac. In at libero sed nunc venenatis imperdiet sed ornare turpis. Donec vitae dui eget tellus gravida venenatis. Integer fringilla congue eros non fermentum. Sed dapibus pulvinar nibh tempor porta.</span></p> <button onclick="myFunction()" id="myBtn">Read more</button></body></html>在這里，閱讀更多按鈕效果很好，但我希望它在顯示其余文本之前顯示一條彈出消息，說明已收到成功付款。請協助
