帶有圖像描述的模態圖像我在這里找到了有關制作多個模態圖像的代碼。然而，當我打開模式時，我似乎找不到添加描述文本的最佳方法。我一直在關注這篇文章的第二個到最后一個答案的代碼： 頁面上的幾個模態圖像 這對我有很大幫助，但我需要描述文本而不是標題文本。如果有人愿意幫助我解決這個問題，我將不勝感激。先感謝您！代碼 ：#myImg { border-radius: 5px; cursor: pointer; transition: 0.3s;}#myImg:hover { opacity: 0.7;}.modal { display: none; /* Hidden by default */ position: fixed; /* Stay in place */ z-index: 1; /* Sit on top */ padding-top: 100px; /* Location of the box */ left: 0; top: 0; width: 100%; /* Full width */ height: 100%; /* Full height */ overflow: auto; /* Enable scroll if needed */ background-color: rgb(0, 0, 0); /* Fallback color */ background-color: rgba(0, 0, 0, 0.9); /* Black w/ opacity */}.modal-content { margin: auto; display: block; width: 80%; max-width: 700px;}#text { margin: auto; display: block; width: 80%; max-width: 700px; text-align: center; color: #ccc; padding: 10px 0; height: 150px;}.modal-content,#text { animation-name: zoom; animation-duration: 0.6s;}@keyframes zoom { from { transform: scale(0) } to { transform: scale(1) }}.close { position: absolute; top: 15px; right: 35px; color: #f1f1f1; font-size: 40px; font-weight: bold; transition: 0.3s;}.close:hover,.close:focus { color: #bbb; text-decoration: none; cursor: pointer;}@media only screen and (max-width: 700px) { .modal-content { width: 100%; }}</style></head>

您需要在單擊后img + text用so 換行，然后按屬性選擇內部內容并更改 modal 。只需對modalImg.src = this.src 進行小修改即可將modalImg.innerHTML = this.innerHTML; 像下面的片段一樣。 我希望下面的片段對您有很大幫助。divwrapped div.innerHTMLimg to divjs code
var modal = document.getElementById('myModal');
// to all images -- note I'm using a class!
var images = document.getElementsByClassName('myImg');
// the image in the modal
var modalImg = document.getElementById("img01");
// and the caption in the modal
var captionText = document.getElementsByClassName("text");
// Go through all of the images with our custom class
for (var i = 0; i < images.length; i++) {
var img = images[i];
// and attach our click listener for this image.
img.onclick = function(evt) {
modal.style.display = "block";
// modalImg.src = this.src;
modalImg.innerHTML = this.innerHTML;
captionText.innerHTML = this.alt;
}
}
var span = document.getElementsByClassName("close")[0];
span.onclick = function() {
modal.style.display = "none";
}
*,*:before, *:after{box-sizing: border-box;}

display: inline-block;

.myImg:hover {

將圖像和文本放在同一個容器中會簡單得多。
<div class="image-container">
<img class="myImg" src="http://onebigphoto.com/uploads/2012/10/midnight-sun-in-lofoten-norway.jpg" alt="Midnight sun in Lofoten, Norway" width="300" height="200">
<div class="text">The Beautiful mountain over the Norway River was a spectacular view to see..</div>
</div>
然后使用 JavaScript 聲明一個名為 modalContent 的變量并選擇您的容器。
var modalContent = getElementById('image-container');
它只是簡化了一切并減少了所需選擇器的數量。查看您的代碼，我無法理解每個圖像是單獨還是全部顯示在模式窗口中。我希望這有幫助。
