http://www.w3schools.com/css/css3_images.asp 上有一个很好的模态图像示例(请向下滚动到“图像模式(高级)”)或查看 http://www.w3schools.com/css/tryit.asp?filename=trycss_image_modal_js对于代码结果

如果我在一个网站上只使用一张图片,它对我来说是完美的。

但我想将图像模式用于不止一个图像。

如果我用相同的代码创建第二张图片,它就在那里,但是当你点击它时它不会打开模式

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

// Get the image and insert it inside the modal - use its "alt" text as a caption
var img = document.getElementById('myImg');
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
img.onclick = function(){
modal.style.display = "block";
modalImg.src = this.src;
modalImg.alt = this.alt;
captionText.innerHTML = this.alt;
}

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

// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}
#myImg {
border-radius: 5px;
cursor: pointer;
transition: 0.3s;
}

#myImg:hover {opacity: 0.7;}

/* 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(0,0,0,0.9); /* Black w/ opacity */
}

/* Modal Content (image) */
.modal-content {
margin: auto;
display: block;
width: 80%;
max-width: 700px;
}

/* Caption of Modal Image */
#caption {
margin: auto;
display: block;
width: 80%;
max-width: 700px;
text-align: center;
color: #ccc;
padding: 10px 0;
height: 150px;
}

/* Add Animation */
.modal-content, #caption {
-webkit-animation-name: zoom;
-webkit-animation-duration: 0.6s;
animation-name: zoom;
animation-duration: 0.6s;
}

@-webkit-keyframes zoom {
from {transform:scale(0)}
to {transform:scale(1)}
}

@keyframes zoom {
from {transform:scale(0.1)}
to {transform:scale(1)}
}

/* The Close Button */
.close {
position: absolute;
top: 15px;
right: 35px;
color: #f1f1f1;
font-size: 40px;
font-weight: bold;
transition: 0.3s;
}

.close:hover,
.close:focus {
color: #bbb;
text-decoration: none;
cursor: pointer;
}

/* 100% Image Width on Smaller Screens */
@media only screen and (max-width: 700px){
.modal-content {
width: 100%;
}
}
<!DOCTYPE html>
<html>

<body>


<img id="myImg" src="img_lights.jpg" alt=":) this modal is great" width="300" height="200">

<img id="myImg" src="img_lights.jpg" alt=":( this not" width="300" height="200">

<!-- The Modal -->
<div id="myModal" class="modal">
<span class="close">×</span>
<img class="modal-content" id="img01">
<div id="caption"></div>
</div>


</body>
</html>

我必须在代码中更改什么才能使其正常工作?

最佳答案

var img = document.getElementById('myImg');

这里应该使用动态id。
