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">×</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. Hope this helps :)

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">×</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.
This plugin works great for me.
So I have put together a very rough modal in jsfiddle for you to take hints from.
$("#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 boostrap-modal (althought you didn't mentioned Bootstrap explicity neither), but I loved to see the simple way W3.CSS solved this and I think 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>
I let you a link to the W3School modal image example to see the headers to make W3.CSS work.

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.
