在ckeditor中动态添加toolbargroup项

Question

config.toolbarGroups = [
        { name: 'basicstyles'},
        { name: 'colors'},
        { name: 'links', items : [ 'Source', 'RemoveFormat' , 'Blockquote','BulletedList'] },
        { name: 'clipboard', items: [ 'Undo','Redo'] }
    ];

现在我想将动态读取项目添加到剪贴板

这是我的编辑器初始化，

editor = CKEDITOR.replace('descr',{
            toolbar         : 'Full',
            resize_enabled  : false
            );

先谢谢!!
