You can use jquery to validate ck editor: my solution is using below code:

  $(document).ready(function(){

            $("#manageForm").validate(
            {
              debug: false,
                rules: { 

                    description:{
                         required: function() 
                        {
                         CKEDITOR.instances.description.updateElement();
                        },

                         minlength:10
                    }
                },
                messages:
                    {

                    description:{
                        required:"Please enter Text",
                        minlength:"Please enter 10 characters"


                    }
                }
            });
        });

有一个错字： minlenght:10应该是minlenght:10 minlength:10
