javascript - 幻灯片中的几个模态图像

问题描述

因此，我使用了该线程中的一些代码来使幻灯片的图像可扩展。第一张幻灯片上的图像效果很好，但是当我单击第二张幻灯片上的图像时，整个模态图像会在第一张幻灯片中打开。

我希望幻灯片的每个图像都在它们所在的幻灯片中打开。如何更改我的代码来做到这一点？

// Get the modal
var modal = document.getElementById('myModal');

// Get the image and insert it inside the modal
var img = document.getElementsByClassName('myImg');
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");

var showModal = function() {
  modal.style.display = "block";
  modalImg.src = this.src;
  captionText.innerHTML = this.alt;
}

for (var i = 0; i < img.length; i++) {
  img[i].addEventListener('click', showModal);
}

// 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";
}
.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 */

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


/* Add Animation */

.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%;
  }
}
<div><img src="whatever.jpg" style="max-width: 100%;" class="myImg" alt="whatever"></div>

<div id="myModal" class="modal">
  <span class="close">&times;</span>
  <img class="modal-content" id="img01">
  <div id="caption"></div>
</div>

解决方案

为此，您可以使用http://fancybox.net/ ，您可以在其中找到模态图像的多个选项。您可以在那里制作画廊，也可以使用单个图像作为模态图像。
