试试这个： -

我稍微改了一下。 变化： -

1）。给定Id to Span Tag

2）。 JS中关于Span

的更改代码

3）。正确隐藏了Html中的Div和Img标签。

4）。在css文件中添加了类（.modal-backdrop）

＆＃13;
＆＃13; 
    // 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.getElementById("CloseModal");

    // 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";
        }
    }

您已将eventListener添加到关闭按钮，将另一个添加到窗口。

单击跨度时，将执行两个事件回调。您必须在span的click事件处理程序的回调中使用e.stopPropagation()来阻止它。

＆＃13;
＆＃13; 
// 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(e) {
  e.stopPropagation();
  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";
  }
}
＆＃13; 
/* 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, 0.4);
  /* Black w/ opacity */
}


/* Modal Content */

.modal-content {
  position: relative;
  background-color: #fefefe;
  margin: auto;
  padding: 0;
  border: 1px solid #888;
  width: 80%;
  box-shadow: 0 4px 8px 0 rgba(0, 0, 0, 0.2), 0 6px 20px 0 rgba(0, 0, 0, 0.19);
  -webkit-animation-name: animatetop;
  -webkit-animation-duration: 0.4s;
  animation-name: animatetop;
  animation-duration: 0.4s
}


/* Add Animation */

@-webkit-keyframes animatetop {
  from {
    top: -300px;
    opacity: 0
  }
  to {
    top: 0;
    opacity: 1
  }
}

@keyframes animatetop {
  from {
    top: -300px;
    opacity: 0
  }
  to {
    top: 0;
    opacity: 1
  }
}


/* The Close Button */

.close {
  color: white;
  float: right;
  font-size: 28px;
  font-weight: bold;
}

.close:hover,
.close:focus {
  color: #000;
  text-decoration: none;
  cursor: pointer;
}

.modal-header {
  padding: 2px 16px;
  background-color: #5cb85c;
  color: white;
}

.modal-body {
  padding: 2px 16px;
}

.modal-footer {
  padding: 2px 16px;
  background-color: #5cb85c;
  color: white;
}

.vege {
  float: left;
  width: 50%;
}
