我找到了如何创建模态的信息 https://www.w3schools.com/howto/tryit.asp?filename=tryhow_css_modal2

事实上我没有java脚本知识

我需要你帮助我在一个 .html 页面中创建 4 或 5 个 JavaScript 模式

我已经尝试过这段代码:

<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无法正确显示

最佳答案

Hello 模态正在使用 ID,我们不能使用相同的 ID,因此,我们需要像这样为每个模态使用特定变量并删除 <script>来自片段

// 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";
}
}
