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

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()
        }
    })
};

All very simple:

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

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

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

Answer 3

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

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!

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"]
			    ],  
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<link href="http://netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" rel="stylesheet"/>

    </div>

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%'
     });
   })
