<script>
        Ext.onReady(function() {
            var TextArea = Ext.getCmp('ta');
            var HtmlEditor = MODx.load({
                xtype: 'modx-htmleditor',
                anchor: TextArea.anchor,
                width: 'auto',
                height: TextArea.height,
                name: TextArea.name,
                value: TextArea.getValue()
            });
    
            TextArea.el.dom.name = '';
            TextArea.el.setStyle('display', 'none');

            TextArea.getValue = function(){
                return HtmlEditor.getValue();
            };

            HtmlEditor.render(TextArea.el.dom.parentNode);
            HtmlEditor.editor.on('key', function(e){TextArea.fireEvent('keydown', e);});
        });
