Subject: [PATCH 1/2] Updating bug for fields with no Name nor Id

When using some WYSIWYG like summernote, by default, contenteditable area has not Id nor Name, in this cases the script generates error in "escapeCssMeta()" when trying to do replace on undefined because the string arg is the result of "idOrName()" on line #1009.
