我正在做一個網站項目。我在 w3schools 中看到了圖像動畫。我已經試過了，它只適用于一張照片——// Get the modalvar modal = document.getElementById('myModal');// Get the image and insert it inside the modalvar img = document.getElementById('a');var modalImg = document.getElementById("img01");img.onclick = function() {  modal.style.display = "block";  modalImg.src = this.src;}// Get the <span> element that closes the modalvar span = document.getElementsByClassName("close")[0];// When the user clicks on <span> (x), close the modalspan.onclick = function() {  modal.style.display = "none";}但我想將它用于多個圖像。所以我創建了一個這樣的函數：function myBeautifulFunc(imageId, modalImageId) {  var modal = document.getElementById('myModal');  var img = document.getElementById(imageId);  var modalImg = document.getElementById(modalImageId);    img.onclick = function() {    modal.style.display = "block";    modalImg.src = this.src;  }  // Get the <span> element that closes the modal  var span = document.getElementsByClassName("close")[0];  // When the user clicks on <span> (x), close the modal  span.onclick = function() {    modal.style.display = "none";  }}并調用了這個函數：myBeautifulFunc('a', 'img01')結果是：它適用于第一張圖片，但是當我在第二張嘗試時，它看起來像這樣：https ://ibb.co/Mk8Xw1Z當我點擊它時，我只想顯示一張圖片，但它顯示了兩張圖片。我怎么解決這個問題？
