如何显示带有悬停效果字幕的模态图像？

Question

我有一个响应式图像网格，工作正常，我很满意。

现在我想为图像添加悬停效果，以便应用白色半透明滤镜并在图像上显示包含图像更多细节的文本。我还希望图像在单击时是模态的和弹出的。

当我应用悬停效果时，弹出图像似乎停止工作。谁能告诉我出了什么问题？注意：我知道悬停效果并未应用于所有图像。这是因为当我意识到它不起作用时我没有打扰。

var modalEle = document.querySelector(".modal");
var modalImage = document.querySelector(".modalImage");
Array.from(document.querySelectorAll(".ImgThumbnail")).forEach(item => {
   item.addEventListener("click", event => {
      modalEle.style.display = "block";
      modalImage.src = event.target.src;
   });
});
document.querySelector(".close").addEventListener("click", () => {
   modalEle.style.display = "none";
});

Answer 1

查看演示：https://codepen.io/turibamwe/pen/xxwGozx

使用这个 javascript:

<script>
var modalEle = document.querySelector(".modal");
var modalImage = document.querySelector(".modalImage");
Array.from(document.querySelectorAll(".ImgThumbnail + .overlay")).forEach(item => {
  var itemImage = item.parentNode.firstElementChild.getAttribute("src");
   item.addEventListener("click", event => {
      modalEle.style.display = "block";
      modalImage.src = itemImage//event.target.src;
   });
});
document.querySelector(".close").addEventListener("click", () => {
   modalEle.style.display = "none";
});
</script>

欢迎来到论坛:)

听起来好像当光标悬停在您的图像上时，悬停状态基本上是分层的在您的可点击图像元素的顶部，因此阻塞用户单击它并激活 pop-up 模式。尝试将您的侦听器也添加到您的悬停状态元素，或者将标题与图像组合在一起，以便它们都可以被点击。我已将您的示例与下面的此代码段配对。

干杯！

var modalEle = document.querySelector(".modal");
var modalImage = document.querySelector(".modalImage");
Array.from(document.querySelectorAll(".overlay")).forEach(item => {
  item.addEventListener("click", event => {
    modalEle.style.display = "block";
    modalImage.src = event.target.parentNode.querySelector(".ImgThumbnail").src;
  });
});
document.querySelector(".close").addEventListener("click", () => {
  modalEle.style.display = "none";
});

  color: #66704D;
  letter-spacing: 3px;
}


/*overlay*/

.container {
  position: relative;
  width: 300px;
  height: 200px;
}

.ImgThumbnail {
  display: block;
  width: 100%;

.overlay {
  position: absolute;
  top: 0;

  opacity: 0;
  transition: .5s ease;
  background-color: rgba(255, 255, 255, 0.9);
}

.container:hover .overlay {
  opacity: 1;
}

.text {
  color: #66704d;
  font-size: 20px;

  -webkit-transform: translate(-50%, -50%);
  -ms-transform: translate(-50%, -50%);
  transform: translate(-50%, -50%);
  text-align: center;
}


/*modal*/

.ImgThumbnail {

.modal {
