In Bootstrap open Enlarge image in modal

371k Views Asked by At

How do I open / enlarge an image in a modal using jquery / js and not data attributes?

Anytime a user inserts an image into a content editor I need it to be clickable to expand in a modal with js, so I cannot rely on the user to input data attributes they don't know how to use.

I tried:-

<a href="/myImage.png" id="pop">
    <img src="/myImage.png" style="width: 400px; height: 264px;">
    Click to Enlarge
</a>

jQuery :-

$("#pop").on("click", function() {
   $(this).modal();
});

Do I need to add info to the jquery to pass the image source to appear in the modal?

Thank you!!!

You can try this code if you are using bootstrap 3:

HTML

<a href="#" id="pop">
    <img id="imageresource" src="http://patyshibuya.com.br/wp-content/uploads/2014/04/04.jpg" style="width: 400px; height: 264px;">
    Click to Enlarge
</a>
    
<!-- Creates the bootstrap modal where the image will appear -->
<div class="modal fade" id="imagemodal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">&times;</span><span class="sr-only">Close</span></button>
        <h4 class="modal-title" id="myModalLabel">Image preview</h4>
      </div>
      <div class="modal-body">
        <img src="" id="imagepreview" style="width: 400px; height: 264px;" >
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>
  </div>
</div>

JavaScript:

$("#pop").on("click", function() {
   $('#imagepreview').attr('src', $('#imageresource').attr('src')); // here asign the image to the modal when the user click the enlarge link
   $('#imagemodal').modal('show'); // imagemodal is the id attribute assigned to the bootstrap modal, then i use the show function
});

This is the working fiddle.

This plugin works great for me.

So I have put together a very rough modal in jsfiddle for you to take hints from.

JSFiddle

$("#pop").on("click", function(e) {
  // e.preventDefault() this is stopping the redirect to the image its self
  e.preventDefault();
  // #the-modal is the img tag that I use as the modal.
  $('#the-modal').modal('toggle');
});

The part that you are missing is the hidden modal that you want to display when the link is clicked. In the example I used a second image as the modal and added the Bootstap classes.

I know your question is tagged as bootstrap-modal (although you didn't mention Bootstrap explicity either), but I love to see the simple way W3.CSS solved this and I think it is good to share it.

  <img src="/myImage.png" style="width:30%;cursor:zoom-in"
  onclick="document.getElementById('modal01').style.display='block'">

  <div id="modal01" class="w3-modal" onclick="this.style.display='none'">
    <div class="w3-modal-content w3-animate-zoom">
      <img src="/myImage.png" style="width:100%">
    </div>
  </div>

Here is a link to the W3Schools modal image example to see the headers to make W3.CSS work.

Here is a solution I'm using for Bootstrap 5.

<!-- a link that triggers modal -->
<a href="#myModal" type="" class="" data-bs-toggle="modal" data-bs-target="#myModal">More details</a>

<div class="modal fade" id="myModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog modal-lg modal-dialog-scrollable">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">Image Title</h5>
        <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
      </div>
      <div class="modal-body">
        <!--        include image here-->
        <img src="images/img_example_8.png" alt="Image Title" class="img-fluid">
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
      </div>
    </div>
  </div>
</div>

The top-voted solution did not work for me as it uses Bootstrap 3 and my app does not. Basically I just followed the bootstrap 5 modal documentation. I made the modal size large so the image is larger.

I have change it little bit but still can not do few things.

I added that clicking on it close it - it was easy but very functional.

 <div class="modal-dialog" data-dismiss="modal">

I also need different description under each photo. I added description in footer just to show what I need. It need to change with every photo.

HTML

<div class="modal fade" id="imagemodal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog" data-dismiss="modal">
      <div class="modal-content"  >              
        <div class="modal-body">
          <button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">&times;</span><span class="sr-only">Close</span></button>
             <img src="" class="imagepreview" style="width: 100%;" >
        </div> 
     <div class="modal-footer">
       <div class="col-xs-12">
           <p class="text-left">1. line of description<br>2. line of description <br>3. line of description</p>
       </div>
     </div>         
   </div>
 </div>

JavaScript:

$(function() {
    $('.pop').on('click', function() {
        $('.imagepreview').attr('src', $(this).find('img').attr('src'));
        $('#imagemodal').modal('show');   
    });     
});

Also it would be nice if this window will open only on 100% of screen. Here picture inside with description have more than 100% and in become scrollable... and if screen in much bigger than pictures it shoud stop only on orginal size. for ex. 900 px and no bigger in height.

The two above it is not run.

The table edit button:

<a data-toggle="modal" type="edit" id="{{$b->id}}" data-id="{{$b->id}}"  data-target="#form_edit_masterbank" data-bank_nama="{{ $b->bank_nama }}" data-bank_accnama="{{ $b->bank_accnama }}" data-bank_accnum="{{ $b->bank_accnum }}" data-active="{{ $b->active }}" data-logobank="{{asset('components/images/user/masterbank/')}}/{{$b->images}}" href="#"  class="edit edit-masterbank"   ><i class="fa fa-edit" ></i></a>

and then in JavaScript:

$('.imagepreview555').attr('src', logobank);

and then in HTML:

<img src="" class="imagepreview555"  style="width: 100%;" />

Not it runs.

If you have an editor, this mean the images are dynamically added by Javascript, so when using jQuery you need to select the image tag starting from an object that is already in page.

My answer will work for both cases: images displayed when page load and images dynamically added after by Javascript.

I am using a class that can be added and will open the image in modal.

The image:

<img src='/assets/image.png' style='width:100px;' class='imageViewBig'/>

The modal:

<div class="modal fade" id="modalImgageView" tabindex="-1" aria-hidden="true">
<div class="modal-dialog modal-lg">
    <div class="modal-content">
        <div class="modal-body text-center">
            <button type="button" class="btn-close bg-dark" data-bs-dismiss="modal" aria-label="Close" style="position:absolute; top:5px;right:5px;"></button>
            <img src="assets/images/nophoto.png" alt="Image Title" class="img-fluid" id="modalImgageViewIMG">
        </div>
    </div>
</div></div>
  • the modal header and footer are removed
  • the "close" button is moved over the image in right corner
  • image from modal have id "modalImgageViewIMG" and is needed to change the "src" attribute

The jQuery:

$(document).on("click", ".imageViewBig", function() {
    let url = $(this).attr('src');
    $('#modalImgageViewIMG').attr('src', url);
    $('#modalImgageView').modal('toggle');

});
  • click event is set on $(document)
  • class "imageViewBig" have a listener for "click" event and will take the "src" from the clicked image and putted to image from modal
