如何添加多个模态？

Question

我目前正在从事博客设计，无法创建多个模式。 我认为应该在Javascript中定义模式。

 // 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"; } } 

 /* 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; } 

 <h2>Animated Modal with Header and Footer</h2> <!-- Trigger/Open The Modal --> <button id="myBtn">Open Modal</button> <!-- The Modal --> <div id="myModal" class="modal"> <!-- Modal content --> <div class="modal-content"> <div class="modal-header"> <span class="close">&times;</span> <h2>Modal Header</h2> </div> <div class="modal-body"> <p>Some text in the Modal Body</p> <p>Some other text...</p> </div> <div class="modal-footer"> <h3>Modal Footer</h3> </div> </div> </div>

由于您使用的是jQuery，因此可以通过使用通用类（例如：

<button class="myBtn">Open Modal 1</button>

<div class="modal">
  <div class="modal-content">
    <div class="modal-header">
      <span class="close">&times;</span>
      <h2>Modal Header 1</h2>
    </div>
    <div class="modal-body">
      <p>Some text in the Modal Body 1</p>
      <p>Some other text...</p>
    </div>
    <div class="modal-footer">
      <h3>Modal Footer 1</h3>
    </div>
  </div>
</div>

JS：

$('.myBtn').on('click', function(){
  $(this).next('.modal').show();
})

$('.close').on('click', function(){
  $(this).closest('.modal').hide();
})

希望这可以帮助。

 $('.myBtn').on('click', function(){ $(this).next('.modal').show(); }) $('.close').on('click', function(){ $(this).closest('.modal').hide(); }) 

 .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; }
