我目前正在嘗試制作多張圖片，點擊時會有不同的圖片
例如，當您單擊雪山影像時，它將顯示一張海灘影像，類似于以下內容：

對于您可以從 onClick 事件獲取 id 的每個 img 標簽，id 必須是唯一的。
function modal_open(clicked_id)
{
var modal = document.getElementById("myModal");
var img = document.getElementById(clicked_id);
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
img.onclick = function(){
modal.style.display = "block";
modalImg.src = this.src;
captionText.innerHTML = this.alt;
}
// 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";
}
}body {font-family: Arial, Helvetica, sans-serif;}
#myImg {
border-radius: 5px;
cursor: pointer;
transition: 0.3s;
}
#myImg:hover {opacity: 0.7;}

</div>uj5u.com熱心網友回復：
您的錯誤是因為 onclick 函式試圖將“假設”帶有 IDsrc的元素的 url 分配給，但 html 沒有帶有 id 的元素。<img>img01<img>
參考@Robin Hood答案，他的代碼解釋了正確的實作方式。
uj5u.com熱心網友回復：
根據@Robin Hood 的回答，我稍微調整了一下，讓您可以使用影像上的資料屬性指定您選擇的路徑。
所以喜歡
<img id="myImg1" src="https://www.w3schools.com/howto/img_lights.jpg" alt="修復多個影像中的問題，單擊時會顯示不同的影像？" data-path="https://picsum.photos/500?random=2" style="width:100%;max-width:300px" onm ouseover="modal_open(this.id)">
data-path="https://picsum.photos/500?random=2"是您放置要在模式中顯示的影像的源 URL 的位置。
還有一個小的 JS 調整，CSS 保持不變

var modal = document.getElementById("myModal");
var img = document.getElementById(clicked_id);
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");

modalImg.src = this.dataset.path; /* THIS IS THE ONLY JS CHANGE */
captionText.innerHTML = this.alt;
