How to make the inline CKEditor scroll inside div?

Question

The inline CKEditor is scrolling with the text correctly when the scroll is done on body. The following is an official demo.

http://sdk.ckeditor.com/samples/inline.html

However, when the scroll is not in a body but in a iframe or div, the scroll is not working even till the latest version now (version 4.5.5). There are some question asked here, for example,

Ckeditor inline editor stays on screen when scrolling a "scrollable" div

This solution works but I may have more than 20 editor on the same page and checking everyone is too heavy for my page.

CKEditor inline editor on elements within an iframe

Another solution that looks fine is not working for me, but what I want is some light solution like this one.

P.S. For those who want to test if your solution is working, here is beginning of the code that you may test on: https://jsfiddle.net/pteryvk3/6/

Answer 1

A bit tricky but I think this solution will work for you: https://jsfiddle.net/yfa5pjtx/1/

Note that in order to position the toolbar correctly I used the jquery-ui lib. It's possible to do positioning calculations without it, but it's much easier to use jquery-ui for that.

This is function that will do the magic for you:

function repositionCKEditorToolbar() {
    // If we don't have any active instance of CKEDITOR - return
    if (!CKEDITOR.currentInstance) {
        return;
    }
    // Save the elements we need to work with
    currentActiveEditor = $(CKEDITOR.currentInstance.element.$)
    currentToolbar = $('#cke_' + currentActiveEditor.attr('id'))

    // Save the heights we will need
    toolbar_height = currentToolbar.height()
    parent_height = currentActiveEditor.parent().outerHeight(true)

    if (currentActiveEditor.position().top > parent_height) {
        // In case the toolbar is "out" of the container we should hide it.
        // It can happen because the toolbar is placed (in the DOM) outside the container.
        currentToolbar.css({top: '-1000px'})
    } else if (currentActiveEditor.position().top > toolbar_height) {
        // In case we have enough space to position the toolbar above the editor
        currentToolbar.position({my: "left bottom", at: "left top", of: currentActiveEditor, collision: "none none"})
    } else {
        if (parent_height - currentActiveEditor.height() - currentActiveEditor.position().top > toolbar_height) {
            // Only if have enough space under the editor and that area is visible - put the toolbar there.
            currentToolbar.position({my: "left top", at: "left bottom", of: currentActiveEditor, collision: "none none"})
        }
    }
}
$('#container').on('scroll', function() {
    // Call the repositioning function on each scroll of the container
    repositionCKEditorToolbar();
});

UPDATE

Here is the same code, but without the requirements of JQuery-UI lib: Note the new absolutePositionFromTop function that is responsible for the feature we needed from the jquery-ui lib.

function absolutePositionFromTop(el) {
    fromTop = 0;
    while ($(el)[0] != $('body')[0]) {
        fromTop = fromTop + $(el).position().top
        el = $(el).parent()
    }
    return fromTop;
}

function repositionCKEditorToolbar() {
    // If we don't have any active instance of CKEDITOR - return
    if (!CKEDITOR.currentInstance) {
        return;
    }
    // Save the elements we need to work with
    currentActiveEditor = $(CKEDITOR.currentInstance.element.$)
    currentToolbar = $('#cke_' + currentActiveEditor.attr('id'))

    // Save the heights we will need
    toolbar_height = currentToolbar.height()
    parent_height = currentActiveEditor.parent().outerHeight(true)

    if (currentActiveEditor.position().top > parent_height) {
        // In case the toolbar is "out" of the container we should hide it.
        // It can happen because the toolbar is placed (in the DOM) outside the container.
        currentToolbar.css({top: '-1000px'})
    } else if (currentActiveEditor.position().top > toolbar_height) {
        // In case we have enough space to position the toolbar above the editor
        newTop = absolutePositionFromTop(currentActiveEditor) - currentToolbar.height()
        currentToolbar.css({top : newTop + 'px'});
    } else {
        if (parent_height - currentActiveEditor.height() - currentActiveEditor.position().top > toolbar_height) {
            // Only if have enough space under the editor and that area is visible - put the toolbar there.
            newTop = absolutePositionFromTop(currentActiveEditor) + currentActiveEditor.height()
            currentToolbar.css({top : newTop + 'px'});
        }
    }
}
$('#container').on('scroll', function(ev) {
    // Call the repositioning function on each scroll of the container
    repositionCKEditorToolbar();
});

And a working jsfiddle.

Great. Will give out the bounty and mark as correct answer if there are no better answer few days later, or if you provide a version without using jquery-ui now. – Landis

As of 4.4.3 this answer will also help: https://mcmap.net/q/664737/-ckeditor-quot-overflow-scroll-quot-on-parent-causes-toolbar-to-freeze-at-initial-position (one-liner) – Eratosthenes

Answer 2

The answer you linked to should work for you: https://mcmap.net/q/664736/-ckeditor-inline-editor-on-elements-within-an-iframe

But instead of using a costly .find(), put your ckeditor instances into an array and then loop through the array, accessing your elements with a snappy document.getElementsByClassName('ckeditor'); or something similar

Imprisonment

Mind giving a working example? You may take this jsfiddle that is not working as a start. jsfiddle.net/pteryvk3/6 Very likely to give you the bounty if you are able to give a working example. – Landis

Answer 3

https://jsfiddle.net/fxrgcauL/embedded/result/

function isScrolledOutOfView(container, elem) {
  var $elem = $(elem);
  var $container = $(container);

  var docViewTop = $container.scrollTop();
  var docViewBottom = docViewTop + $container.height();

  var elemTop = $elem.offset().top;
  var elemBottom = elemTop + $elem.height();

  return elemTop <= (docViewTop - $container.height());
}
$('#container').on('scroll', function(ev) {
  var container = this,
    currentEditor = CKEDITOR.currentInstance;
  if (typeof(currentEditor) != "undefined" && currentEditor != null) {
    if (isScrolledOutOfView(container, $('#' + currentEditor.element.$.id))) {
      currentEditor.fire('blur');
      $('#' + currentEditor.element.$.id).trigger('blur');
    }
  }
})

This is just making the editor box disappear when the div scroll out of the screen, but what I want is the editor box scroll together with the div, as shown in the official example. – Landis

I'm not sure I understand. i don't see the toolbox scrolling with it. Can you go to recordit.co and create a video so I can see what you mean? It's probably because you have a different resolution that it looks different. – Lanctot

Answer 4

Short and simple one write css override class

.cke_contents {
 overflow-y: scroll;
}

If scroll needs in all creditors. Else take the id of particular to override same as above. This will give the scroll to your content.

PS. Use inspect element to check your class. May be class name is different.

Latashialatch

I think you don't understand my question. There is a toolbox when you click the editablecontent div. What I want is the toolbox to be moving when you are scrolling the div. (like the action in the official example) – Landis
