How to Destroy CKEditor in small screen devices

The CKeditor fires an event instanceReady once the instances are ready to be used.

So we need to create a listener which will listen for this event.

We will only execute the event handler if the browser window width is less than the some defined width for a small screen devices.

In Jquery the width of the browser window can be determined by $.width() method by calling on window object.

<script type="text/javascript">
$(document).ready(function() {
    function destroyCKEditor(minWidth) {
        if (typeof CKEDITOR != 'undefined' 
            && $( window ).width() < minWidth) {
            CKEDITOR.on("instanceReady", function(event)
            {
               $.each(CKEDITOR.instances, function(index, instance) {
                    instance.destroy();
               });
            });
        };
    }
    //usage 
    //destroy ck editor in devices less than 768px wide 
    destroyCKEditor(768);
});
</script>
