尝试这个 ：-

我已经改变了一点。 变化 ：-

1）。 给定 Id 以跨越标签

2）。 更改了 JS 中有关 Span 的代码

3）。 正确关闭 html 中的 Div 和 Img 标签。

4）。 在 css 文件中添加类 (.modal-backdrop)

 // 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"; } }

 /* 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%; } .modal-backdrop { position: fixed; top: 0; right: 0; bottom: 0; left: 0; z-index: 1030; }

谢谢。

您已将一个 eventListener 添加到关闭按钮，并将另一个添加到窗口。

当您单击跨度时，将执行两个事件回调。 您必须通过在 span 的 click 事件处理程序的回调中使用e.stopPropagation()来防止它。

 // 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"; } }

 /* 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%; }
