Fancybox zoom

[DownPW]

Hello @phenomlab

I use fancy box like you on my nodebb Instance but I have no zoom when I click on a image :

I would like to include a zoom button like you and on Sudonix but with the possibility of zooming several times (once on your site) because I have image with little text

Here my code :

Header:

<!-- Fancybox -->
<script src="https://cdn.jsdelivr.net/npm/@fancyapps/ui@5.0/dist/fancybox/fancybox.umd.js"></script>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@fancyapps/ui@5.0/dist/fancybox/fancybox.css"/>

JS :

// ------------------------------------------
// Fancybox Media Reader
// ------------------------------------------
if (top.location.pathname !== '/login') {
    $(window).on('action:posts.loaded', function(data) {
        console.log("Polling DOM for lazyLoaded images to apply Fancybox");
        $(document).ready(function() {
            $('a').not('.forum-logo').not(".avatar").not(".emoji").not(".bmac-noanimate").each(function() {
                $('a[href*=".jpg"], a[href*=".jpeg"], a[href*=".png"], a[href*=".gif"], a[href*=".webp"]').addClass("noanimate");
            });
        });
    });
}
 
if (top.location.pathname !== '/login') {
    $(document).ready(function() {
        $(window).on('action:ajaxify.end', function(data) {
            this.$('a').not('.forum-logo').not(".avatar").not(".emoji").not(".bmac-noanimate").each(function() {
                $('a[href*=".jpg"], a[href*=".jpeg"], a[href*=".png"], a[href*=".gif"], a[href*=".webp"]').addClass("noanimate");
                data.preventDefault()
                // Strip out the images contained inside blockquotes as this looks nasty :)
                $('blockquote img').remove();
            });
            Fancybox.bind(
                'a[href*=".jpg"], a[href*=".jpeg"], a[href*=".png"], a[href*=".gif"], a[href*=".webp"]', {
                    groupAll: true,
                }
            );
        });
    });
}
 
// Chat fancybox - fires when chat module loaded and AJAX calls new chat
$(document).ready(function() {
    $(window).on('action:chat.loaded', function(data) {
            this.$('img').not('.forum-logo').not(".avatar").not(".emoji").not(".bmac-noanimate").each(function() {
                var newHref = $(this).attr("src");
                $(this).wrap("<a class='fancybox' href='" + newHref + "'/>");
                $('a[href*=".jpg"], a[href*=".jpeg"], a[href*=".png"], a[href*=".gif"], a[href*=".webp"]').addClass("noanimate");
                data.preventDefault();
                // Strip out the images contained inside blockquotes as this looks nasty :)
                $('blockquote img').remove();
            });
            Fancybox.bind(
                'a[href*=".jpg"], a[href*=".jpeg"], a[href*=".png"], a[href*=".gif"], a[href*=".webp"]', {
                    groupAll: true,
                }
            );
    });
});

Can you help me for this ?

@DownPW Technically, it should be possible with the addition of the below

          Toolbar: {
          display: {
            left: ["infobar"],
            middle: [
              "zoomIn",
              "zoomOut",
              "toggle1to1",
              "rotateCCW",
              "rotateCW",
              "flipX",
              "flipY",
            ],
            right: ["slideshow", "thumbs", "close"],
          },
        },

Meaning your code block becomes

function fancybox() {
if (top.location.pathname !== '/login') {
    $(document).ready(function() {
        $('a').not('.forum-logo').not(".avatar").not(".emoji").not(".bmac-noanimate").each(function() {
            $('a[href*=".jpg"], a[href*=".jpeg"], a[href*=".png"], a[href*=".gif"], a[href*=".webp"], a[href*=".svg"]').addClass("noanimate");
        });
    });
                Fancybox.bind(
            'a[href*=".jpg"], a[href*=".jpeg"], a[href*=".png"], a[href*=".gif"], a[href*=".webp"], a[href*=".svg"]', {
                          Toolbar: {
          display: {
            left: ["infobar"],
            middle: [
              "zoomIn",
              "zoomOut",
              "toggle1to1",
              "rotateCCW",
              "rotateCW",
              "flipX",
              "flipY",
            ],
            right: ["slideshow", "thumbs", "close"],
          },
        },
            }
        );
}
}

Note, that you just need to add/remove the elements in the toolbar you do not need. Obviously, zoomIn and zoomOut are the ones you are specifically interested in. However, if Fancybox detects that the image has already been zoomed as far as possible, then this will not work. You’d need an external library such as zoom.js to add this functionality, or perhaps simpler

jQuery Zoom

It seems www.jacklmoore.com declined to respond to the data request. The link will still work, but no preview is available.

A good example of how you’d make these two independent libraries work together is below

No preview available

It seems codepen.io declined to respond to the data request. The link will still work, but no preview is available.

It’s worth nothing that this specific code is based on Fancybox 3, so may need to be refactored to work with the latest version 5.
