javascript - 为不同的模态获取相同的图像

Question

即使我有不同的类，我也无法在我的模态中获取相同的图像......我确定这是我的 JS 代码，只是无法弄清楚......非常感谢任何帮助。

我还在学习 JS，但知道的就够危险了！我确信这不是最好的编码方式，但我从 W3schools 获取了基础知识并根据我的需要进行了调整。

起初只有一个模式可以工作，但我想出了如何使代码更详细，现在我得到了相同的图片。

我如何确保它选择了正确的？

这是我的代码：

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

// Get the button that opens the modal
var btn = document.getElementById("myBtn");

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];

// When the user clicks the button, open the modal 
btn.onclick = function() {
  modal.style.display = "block";
}

// When the user clicks on <span> (x), close the modal
span.onclick = function() {
  modal.style.display = "none";
}

// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
  if (event.target == modal) {
    modal.style.display = "none";
  }
}

// Get the modal
var modal2 = document.getElementById("myModal2");

// Get the button that opens the modal
var btn = document.getElementById("myBtn2");

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close2")[0];

// When the user clicks the button, open the modal 
btn.onclick = function() {
  modal.style.display = "block";
}

// When the user clicks on <span> (x), close the modal
span.onclick = function() {
  modal.style.display = "none";
}

// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
  if (event.target == modal) {
    modal.style.display = "none";
  }
}
</script>

<button id="myBtn">1</button> <!-- The Modal -->
<div id="myModal" class="modal"><!-- Modal content -->
  <div class="modal-content">
    <img class="img" src="https://bbk12e1-cdn.myschoolcdn.com/ftpimages/772/misc/misc_190683.123dx" /> 
    <span class="close">&#215;</span>
    <div>This is the Galbraith Building</div>
 </div>
</div>

<button id="myBtn2">2</button> <!-- The Modal -->
<div id="myModal2" class="modal2"><!-- Modal content -->
  <div class="modal-content2">
    <img class="img2" src="https://bbk12e1-cdn.myschoolcdn.com/772/photo/2015/06/orig_photo275070_2980857.jpg" /> 
    <span class="close2">&#215;</span>
  <div>This is the Galbraith Building</div>
</div>

您正在为这两个功能调用第一个模式。将第二组更改为 modal2.style.display ，它应该可以解决您的问题

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

// Get the button that opens the modal
var btn = document.getElementById("myBtn");

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];

// When the user clicks the button, open the modal 
btn.onclick = function() {
  modal.style.display = "block";
}

// When the user clicks on <span> (x), close the modal
span.onclick = function() {
  modal.style.display = "none";
}

// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
  if (event.target == modal) {
    modal.style.display = "none";
  }
}

// Get the modal
var modal2 = document.getElementById("myModal2");

// Get the button that opens the modal
var btn = document.getElementById("myBtn2");

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close2")[0];

// When the user clicks the button, open the modal 
btn.onclick = function() {
  modal2.style.display = "block";
}

// When the user clicks on <span> (x), close the modal
span.onclick = function() {
  modal2.style.display = "none";
}

// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
  if (event.target == modal) {
    modal2.style.display = "none";
  }
}
