How to use CKEditor in a Bootstrap Modal?

Question

If I use the CKEditor plugin in an HTML page based on a Bootstrap template, it works great, however if I insert the editor on a Bootstrap Modal like this

<!-- Modal --> 
<div class="modal fade" id="modalAddBrand" tabindex="-1" role="dialog" aria labelledby="modalAddBrandLabel" aria-hidden="true">   
  <div class="modal-dialog modal-lg">
     <div class="modal-content">
       <div class="modal-header">
         <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
         <h4 class="modal-title" id="modalAddBrandLabel">Add brand</h4>
       </div>
       <div class="modal-body">
             <form>
             <textarea name="editor1" id="editor1" rows="10" cols="80">
             This is my textarea to be replaced with CKEditor.
             </textarea>            <script>
             CKEDITOR.replace('editor1');
             </script>
             </form> 
       </div>
       <div class="modal-footer">
         <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
         <button id="AddBrandButton" type="button" class="btn btn-primary">Save</button>
       </div>
     </div>   
   </div> 
</div>

The editor works, but all the form controls on the popup windows of the editor are disabled, if you try to add a link or an image, for example, you cannot insert the URL or any description because the inputs are disabled.

Any workaround for this issue?

This is a fiddle example: http://jsfiddle.net/7zDay/

Answer 1

This should help http://jsfiddle.net/pvkovalev/4PACy/

$.fn.modal.Constructor.prototype.enforceFocus = function () {
    var $modalElement = this.$element;
    $(document).on('focusin.modal', function (e) {
        var $parent = $(e.target.parentNode);
        if ($modalElement[0] !== e.target && !$modalElement.has(e.target).length
            // add whatever conditions you need here:
            &&
            !$parent.hasClass('cke_dialog_ui_input_select') && !$parent.hasClass('cke_dialog_ui_input_text')) {
            $modalElement.focus()
        }
    })
};

Update October 2016:

CDN link for CKEditor has been changed, so I updated jsfiddle

This is late to answer but doing css trick will solve the issue.

Default z-index of Bootstrap modal is 10051 and default z-index of ckeditor dialog are 10010. The trick is just to increase ckeditor dialog z-index as below. put below code in your css file:

.cke_dialog
{
    z-index: 10055 !important;
}

Answer 3

See the response from aaronsnow to this thread on the ckeditor forum: http://ckeditor.com/forums/Support/Issue-with-Twitter-Bootstrap

He's given the code. Just put the code in js file and make sure you include the file after the jquery and bootstrap

Answer 4

  $(document).on({'show.bs.modal': function () {
                 $(this).removeAttr('tabindex');
      } }, '.modal');

Answer 5

Use the 100% working script..

<script type="text/javascript">
    // Include this file AFTER both jQuery and bootstrap are loaded.
    $.fn.modal.Constructor.prototype.enforceFocus = function() {
      modal_this = this
      $(document).on('focusin.modal', function (e) {
        if (modal_this.$element[0] !== e.target && !modal_this.$element.has(e.target).length 
        && !$(e.target.parentNode).hasClass('cke_dialog_ui_input_select') 
        && !$(e.target.parentNode).hasClass('cke_dialog_ui_input_textarea')
        && !$(e.target.parentNode).hasClass('cke_dialog_ui_input_text')) {
          modal_this.$element.focus()
        }
      })
    };
</script>

Thanks!

Answer 6

I was getting Uncaught TypeError: Cannot read property 'fn' of undefined

So I just replaced the $ inside the script provided by @Pavel Kovalev above to jQuery.

jQuery.fn.modal.Constructor.prototype.enforceFocus = function () {
    modal_this = this
    jQuery(document).on('focusin.modal', function (e) {
        if (modal_this.$element[0] !== e.target && !modal_this.$element.has(e.target).length
                && !jQuery(e.target.parentNode).hasClass('cke_dialog_ui_input_select')
                && !jQuery(e.target.parentNode).hasClass('cke_dialog_ui_input_text')) {
            modal_this.$element.focus()
        }
    })
};

Answer 7

Just open /core/config.js in ckeditor files than change "baseFloatZIndex" variable

baseFloatZIndex = 10000

to

baseFloatZIndex = 20000

It will change the start "z-index" of your editor box and the popups.

Answer 8

Don't know, maybe in my version it's already fixed, but my solution is:

    $("#messageModal").on('shown.bs.modal', function() {
     CKEDITOR.replace('message', {
       height: '400px',
       width: '100%'
     });
   })

Answer 9

All very simple:

$('#modal').removeAttr('tabindex');

$('#modal').focusout(function(){
    $(this).css({'position':'relative'});
});

$('#modal').focusin(function(){
    $(this).css({'position':'fixed'});
});

Answer 10

This is very short and simple. import CKEditor Javascript config files from the path they are store in your app. This is mine

<script type="text/javascript" src="{% static 'ckeditor/ckeditor-init.js' %}"></script>
<script type="text/javascript" src="{% static 'ckeditor/ckeditor/ckeditor.js' %}"></script>

After this you can call CKEditor to replace your textarea by doing this

CKEDITOR.replace('topic', {
          uiColor: '#9AB8F3',
			    language: "en-us",
			    toolbar: "Custom",
          height: "200",
          width: "400",
			    skin: "moono",
			    toolbar_Custom: [
			    	["Bold", "Italic", "Underline"], 
			    	["NumberedList", "BulletedList", "-", "Outdent", "Indent", "-", "JustifyLeft", "JustifyCenter", "JustifyRight", "JustifyBlock"], 
			    	["Link", "Unlink"]
			    ],  
});

Answer 11

I think i found some solution for this.

As @Pavel Kovalev suggested it have something to do with boostraps 4 JS and focus in modal script. I had just same problem as Yours.

There is an option for modals called "focus" which sets focus on initialized modals. Disabling this option makes all Your inputs in CKEditors modals work as they should. Not having focus on this modal i can live without :)

See details here: https://getbootstrap.com/docs/4.3/components/modal/#options

In my approach to this i finaly got something like this:

<div class="modal fade" data-focus="false" id="newsAdd" role="dialog" aria-labelledby="fieldAdd" aria-hidden="true">
...
</div>

Also it is propably good idea for some more extensive testing, especialy if You have multiple bootstrap modals with CKEditor on one page.

As for the all the "fixes" You can propably find on web. Have a look that they most likely refer to bootstrap 3 where events on modal are different so they simply cannot work. Including @Pavel Kovalev solution.

Answer 12

This worked for me with bootstrap 4.4 and ckeditor 4.14. All you need to do is to initialize the ckeditor in your modal's shown.bs.modal event.

$('#yourModal')
    .on('shown.bs.modal', (e) => {
        CKEDITOR.replace('editor')
});

worked like a charm.

Answer 13

I just remove the tabindex="-1" from the dialog main div element. Here is the sample code

<div class="modal fade" id="bs-example-modal-lg" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true">

I just remove this

tabindex="-1"

and it starts working.

Answer 14

For Bootstrap 4, this line will no longer work. They will need to figure out that it changed to:

$.fn.modal.Constructor.prototype._enforceFocus = function() {};

Instead of

$.fn.modal.Constructor.prototype.enforceFocus = function() {};

So, Code should be like this:

$.fn.modal.Constructor.prototype._enforceFocus  = function() {
        modal_this = this
        $(document).on('focusin.modal', function (e) {
          if (modal_this.$element[0] !== e.target && !modal_this.$element.has(e.target).length 
          && !$(e.target.parentNode).hasClass('cke_dialog_ui_input_select') 
          && !$(e.target.parentNode).hasClass('cke_dialog_ui_input_text')) {
            modal_this.$element.focus()
          }
        })
      };

Answer 15

Add this css to set the .cke_dialog_container z-index which is linked to your dialog container

.cke_dialog_container 
{
    z-index: 20000
}

and for the modal I have used something like given in an already answered post:

$("#createLot").on("show.bs.modal", function() {
        $(this).removeAttr('tabindex');
    })

This solved my problem of dialog box on link click.
