带Codeigniter的CKeditor Ajax

I had successfully installed CKeditor plugin on a textarea in Html view in a codeingiter project.

the problem that I use "ajax" form post and it seems that the content of CKeditor textarea does not sent with other fields.

I tried this solution to add

var VariableName = escape(FCKeditorAPI.GetInstance('FCKEditorFieldName').GetXHTML());

but "firebug" show me an error message that "FCKeditorAPI is not defined" then the page redirected to a white page contains json output message.

can you help me to send content of CKeditor textarea with ajax.

Are you using CK editor or FCK editor?

With the first (non-jquery version) you just need the .getData() function to get the data content of the field:

CKEDITOR.replace( 'editor1' );
var field = CKEDITOR.instances.editor1.getData();

If you're using the jQUery Adapter I think it's enough doing:

var field = $( '#editor1' ).val();
