带页眉和页脚的双动画模态

Question

我发现了有关如何创建模态https://www.w3schools.com/howto/tryit.asp?filename=tryhow_css_modal2的信息

实际上我没有Java脚本知识

我需要您，以帮助我在一个.html第4或5页中创建JavaScript模式

我已经尝试过此代码：

 <script> // Get the modal var modal = document.getElementById('myModal'); var modal = document.getElementById('myModal2'); // Get the button that opens the modal var btn = document.getElementById("myBtn"); var btn = document.getElementById("myBtn2"); // 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"; } } </script> 

 <style> /* 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 Hecccccccccccccader</h2> </div> <div class="modal-body"> <p>Some text in the Modal Body</p> <p>Some other cccccccccccctext...</p> </div> <div class="modal-footer"> <h3>Modal ccccccccccccccFooter</h3> </div> </div> </div> <!-- Trigger/Open The Modal --> <button id="myBtn2">Open Modal</button> <!-- The Modal --> <div id="myModal2" class="modal"> <!-- Modal content --> <div class="modal-content"> <div class="modal-header"> <span class="close">&times;</span> <h2>Modaldddddddddddd Header</h2> </div> <div class="modal-body"> <p>Some textdddddddddddddddddd in the Modal Body</p> <p>Some otherdddddddddddddddddddd text...</p> </div> <div class="modal-footer"> <h3>Modal Footer</h3> </div> </div> </div>

结果这些按钮都不起作用或显示不正确

您好，模态正在使用ID，我们不能使用相同的ID，因此，我们需要像这样在模态中使用特定的变量，并从代码段中删除<script>

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

var modal2 = document.getElementById('myModal2');

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

var btn2 = document.getElementById("myBtn2");

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

var span2 = document.getElementsByClassName("close2")[0];

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

btn2.onclick = function() {
    modal2.style.display = "block";
}

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

// When the user clicks on <span> (x), close the modal
span2.onclick = function() {
    modal2.style.display = "none";
}

 // Get the modal var modal = document.getElementById('myModal'); var modal2 = document.getElementById('myModal2'); // Get the button that opens the modal var btn = document.getElementById("myBtn"); var btn2 = document.getElementById("myBtn2"); // Get the <span> element that closes the modal var span = document.getElementsByClassName("close")[0]; var span2 = document.getElementsByClassName("close2")[0]; // When the user clicks the button, open the modal btn.onclick = function() { modal.style.display = "block"; } btn2.onclick = function() { modal2.style.display = "block"; } // When the user clicks on <span> (x), close the modal span.onclick = function() { modal.style.display = "none"; } // When the user clicks on <span> (x), close the modal span2.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) { modal.style.display = "none"; } if (event.target == modal2) { modal2.style.display = "none"; } } 

 /* The Modal (background) */ .modal { display: none; 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); } /* 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,.close2 { color: white; float: right; font-size: 28px; font-weight: bold; } .close:hover, .close:focus,.close2:hover, .close2: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; }
