CKeditor and RSV validator issue

I'm using ckeditor in content management system but can't validate ckeditor textarea. Used following code

$("#submit_btn").click(function () {
    CKEDITOR.instances.content.updateElement();

        });

Now 开发者_运维百科the problems with RSV validator gone but now ckeditor gives bunch of errors

[12:12:41.635] ag.getOuterHtml is not a function @ http://localhost:81/core/includes/ckeditor/ckeditor.js:99
[12:12:41.694] af.getTarget().is is not a function @ http://localhost:81/core/includes/ckeditor/ckeditor.js:99
--
[12:13:40.869] Use of attributes' specified attribute is deprecated. It always returns true. @ http://localhost:81/admin/?page=add

How to fix that?
