javascript - 具有多个图像的模态图像库

问题描述

我试图在我拥有的画廊上获得这个（ https://www.w3schools.com/howto/howto_css_modal_images.asp ）。我已经成功地让它工作了，但它只适用于一张图片，并且不能复制到画廊，因为它只适用于一张图片。

我发现这个人在 3 年前发布了同样的问题（模态图像库 - 多个图像）所以我一直在尝试遵循该修复但一直无法。

我一直在关注链接中的 CSS 和 JS 提示

// 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 = $('.myImg');
var modalImg = $("#img01");
var captionText = document.getElementById("caption");
$('.myImg').click(function() {
  modal.style.display = "block";
  var newSrc = this.src;
  modalImg.attr('src', newSrc);
  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";
}
/* Style the Image Used to Trigger the Modal */

.myImg {
  border-radius: 5px;
  cursor: pointer;
  transition: 0.3s;
}

.myImg:hover {
  opacity: 0.7;
}


/* The Modal (background) */

.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 (Image) */

.modal-content {
  margin: auto;
  display: block;
  width: 80%;
  max-width: 700px;
}


/* Caption of Modal Image (Image Text) - Same Width as the Image */

#caption {
  margin: auto;
  display: block;
  width: 80%;
  max-width: 700px;
  text-align: center;
  color: #ccc;
  padding: 10px 0;
  height: 150px;
}


/* Add Animation - Zoom in the Modal */

.modal-content,
#caption {
  -webkit-animation-name: zoom;
  -webkit-animation-duration: 0.6s;
  animation-name: zoom;
  animation-duration: 0.6s;
}

@-webkit-keyframes zoom {
  from {
    -webkit-transform: scale(0)
  }
  to {
    -webkit-transform: scale(1)
  }
}

@keyframes zoom {
  from {
    transform: scale(0)
  }
  to {
    transform: scale(1)
  }
}


/* The Close Button */

.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;
}


/* 100% Image Width on Smaller Screens */

@media only screen and (max-width: 700px) {
  .modal-content {
    width: 100%;
  }
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<!-- Trigger the Modal -->
<img id="SD" class="myImg" src="SD.jpg" alt="SD B">

<!-- The Modal -->
<div id="myModal" class="modal">

  <!-- The Close Button -->
  <span class="close" onclick="document.getElementById('myModal').style.display='none'">&times;</span>

  <!-- Modal Content (The Image) -->
  <img class="modal-content" id="modal-image">

  <!-- Modal Caption (Image Text) -->
  <div id="caption"></div>
</div>

Here is the fully working code: https://jsfiddle.net/dmvshn/75ueLgbt/
