想要创建多个Modal弹出窗口..下面的代码适用于一个弹出窗口，但我怎样才能做3个弹出窗口？我只是在学习.. https://www.w3schools.com/howto/tryit.asp?filename=tryhow_css_modal显然整个代码都不会粘贴..使用手机

<!DOCTYPE html>
<html>
<head>
<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 {
background-color: #fefefe;
margin: auto;
padding: 20px;
border: 1px solid #888;
width: 80%;
}

/* The Close Button */
.close {
color: #aaaaaa;
float: right;
font-size: 28px;
font-weight: bold;
}

.close:hover,
.close:focus {

</div>

</div>
<script>
// 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";
}
}
</script>

您需要为每个模态提供唯一的ID并相应地绑定按钮。需要复制和更改的三件事是

按钮ID id =＆＃34; myBtn＆＃34; 改为 id =＆＃34; myBtn2＆＃34;
模态ID id =＆＃34; myModal＆＃34; 指向 id =＆＃34; myModal2＆＃34;
javascript按ID document.getElementById（＆＃39; myModal＆＃39;）;

现在，你的两个模态具有相同的id，而id应该是唯一的。因此，如果你想要第二个模态（并且你希望通过它的id与JavaScript中的模态进行交互），那么你需要为第二个模态分配一个唯一的id。

多个模态弹出窗口
