How To Enlarge Multiple Pictures Using JavaScript
click picture outcome that I want with multiple pictures though I've been tasked with fixing this problem out and I just can't grasp it. I want to enlarge multiple pictures using J
Solution 1:
Here is a working solution using onclick. you have to pass image id dynamically in to script. Hope this will help your study.
function openModal(id) {
// 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(id);
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
modal.style.display = "block";
modalImg.src = img.src;
captionText.innerHTML = img.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";
}
} img: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 {-webkit-transform: scale(0)}
to {-webkit-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%;
}
}

<h2>Image Modal</h2>
<p>In this example, we use CSS to create a modal (dialog box) that is hidden by default.</p>
<p>We use JavaScript to trigger the modal and to display the current image inside the modal when it is clicked on. Also note that we use the value from the image's "alt" attribute as an image caption text inside the modal.</p>
<p>Don't worry if you do not understand the code right away. When you are done with CSS, go to our JavaScript Tutorial to learn more.</p>
<img id="myImg1" src="https://www.gstatic.com/webp/gallery/1.sm.jpg" alt="Pink hair kitty cat ^-^" width="300" height="200" onclick="openModal(this.id)">
<img id="myImg2" src="https://www.gstatic.com/webp/gallery/2.jpg" alt="Black hair kitty cat ^-^" width="300" height="200" onclick="openModal(this.id)">
<!-- The Modal -->
<div id="myModal" class="modal">
<span class="close">×</span>
<img class="modal-content" id="img01">
<div id="caption"></div>
</div>
</body>
</html>Solution 2:
You can make use of onclick event on image click. So i have added a onclick= somefunct(this) on each images.
Also make sure you include your script just above the closing body tag
i.e.
</body>
Now you can observe that the el that is passed as argument in somefunct is the element itself.
SO i have also modified your
var img = document.getElementById('myImg')
to
var img = el;
Also modified:
modalImg.src = this.src;
captionText.innerHTML = this.alt;
to
modalImg.src = el.src;
captionText.innerHTML = el.alt;
Here is the complete working one:
