Question

我有一个简单的图像库，其中包含缩略图，当您单击图像时，图像会在弹出窗口中展开。

我的问题是我只能使此功能使用一张图像。

我知道身体在呼唤

<div id="myModal" class="modal">

<img class="modal-content" id="img01

并且脚本正在调用

var modalImg = document.getElementById("img01");

我无法弄清楚我需要对这些元素执行哪些操作才能使弹出功能适用于所有缩略图？任何帮助将是巨大的！

代码：

// Get the modal
var modal = document.getElementById('myModal');

// Get the image and insert it inside the modal - use its "alt" text as a 
caption
var img = document.getElementById('myImg');
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";
}

.thumbnails img {
  height: 80px;
  border: 4px solid #fff;
  padding: 1px;
  margin: 0 10px 10px 0;
}

.thumbnails img:hover {
  border: 4px solid #00ccff;
  cursor: pointer;
}

.thumbnails h2 {
  color: white;
}

.thumbnails h3 {
  color: white;
}

#myImg {
  border-radius: 0px;
  cursor: pointer;
  transition: 0.3s;
}

#myImg:hover {
  opacity: 0.7;
}

Answer 1

您正在使用唯一的ID。尝试使用类。

Answer 2

您是否对所有图像都使用相同的ID，如果是的话，因为ID是唯一的，将无法使用。您不能为不同的元素分配相同的ID

CSS和脚本库调整
