feeding elements with data, which contains ckeditor json2

Dear Sirs and Madam,

when trying to include json2.js

 CKEDITOR.scriptLoader.load( 'path_to_json2.js' );

in the window.onload function the ckeditor is not initializing anymore. When I ommit the inclusion, it works. firebug reports:

T[V].replace is not a function

in while have json2.js included.

I am trying to supply additional form-elements with data by ajax. Lastly I simply echoed html_entity_decoded html-code to the ajax handler which sets the contents of the editor, successfully.

Now I want to replace the simple echoing by a JSON formatted string, to get additional form-elements with data supplied,

$res = $db->get_content_by_id($par[0]);
$txstring = json_encode($res,null);
echo $txstring;

which delivers

[{"id":"4","description":"freizeit->videos","typ":"passage","htmlsnippet":"Olympus LS-20m"}]

in the editor.

While trying to decode the information on the client-js-side with:

var data = str.evalJSON();

it claims that evalJSON is not found. (since I omitted the inclusion of json2.js.


Is there a way to run json2.js with the "built-in" json of ckeditor in parallel?
If not, could anybody point me how to use ckeditors included json interface to feed the json-string to the individual form-elements , please ?

Hopefully it is clear what I intend to do.

thanks in advance and best regards
