链接到启动模式窗口而不是图像？

Question

我希望有人可以帮助我，因为我是一名业余编码员，并且我花了最近3或4个小时来尝试解决这个问题。与其单击窗口以模态启动我的图像，不如单击该链接以启动它，如何制作它？谢谢您的帮助！这是javascript，CSS和html：

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

modal.addEventListener('click',function(){
this.style.display="none";
})

// 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";
}

// Get all images and insert the clicked image inside the modal
// Get the content of the image description and insert it inside the modal image caption
var images = document.getElementsByTagName('img');
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
var i;
for (i = 0; i < images.length; i++) {
  images[i].onclick = function() {
    modal.style.display = "block";
    modalImg.src = this.src;
    modalImg.alt = this.alt;
    captionText.innerHTML = this.nextElementSibling.innerHTML;
  }
}

img.responsive {
  float: left;
  width: 32%;
  margin: 30px;
  float: left;
}

img.responsive:hover {
  border: 2px solid hotpink;
  cursor: pointer;
}


/* 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: rgba(0, 0, 0, 0.9);
  /* Black w/ opacity */
}


/* Modal Content (image) */

.modal-content {
  margin: auto;
  display: block;
}

/* 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 {
    transform: scale(0)
  }
  to {
    transform: scale(1)
  }
}

@keyframes zoom {
  from {
    transform: scale(0.1)
  }
  to {
    transform: scale(1)
  }
}


/* The Close Button */

.close {
  position: absolute;
  top: 75px;
  right: 35px;
  color: white;
  font-size: 60px;
  font-weight: bold;
  transition: 0.3s;
}

.close:hover,
.close:focus {
  color: white;
  text-decoration: none;
  cursor: pointer;
}

/* Clear Floats */

.clearfix:after {
  content: "";
  display: table;
  clear: both;
}

<img class="responsive" src="https://i.imgur.com/cQy7Yg.jpg">
<div class="clearfix"></div>

<!-- The Modal -->
<div id="myModal" class="modal">
  <span class="close">×</span>
  <img class="modal-content" id="img01">
  <div id="caption"></div>
</div>

您需要对代码进行以下更改才能做到这一点。希望对您有帮助！

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

modal.addEventListener('click', function() {
  this.style.display = "none";
})

// 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";
}



function launchModal(element) {
  // Get all images and insert the clicked image inside the modal
  // Get the content of the image description and insert it inside the modal image caption
  //var images = document.getElementsByTagName('img');
  var modalImg = document.getElementById("img01");
  var captionText = document.getElementById("caption");
  //var i;
  //for (i = 0; i < images.length; i++) {
  //images[i].onclick = function() {
  modalImg.src = element.getAttribute('data-src');
  modalImg.alt = this.alt;
  captionText.innerHTML = element.parentElement.children[1].innerHTML;
  modal.style.display = "block";
  //}
  //}
}

img.responsive {
  float: left;
  width: 32%;
  margin: 30px;
  float: left;
}

img.responsive:hover {
  border: 2px solid hotpink;
  cursor: pointer;
}


/* The Modal (background) */

.modal {

  /* Sit on top */
  padding-top: 100px;
  /* Location of the box */

  top: 0;
  width: 100%;
  /* Full width */
