how to validate an fckeditor using javascript

i have had some problems finding out how to validate the fckeditor. i just found out. in between the script tags for javascript, declare a variable for the edior: var editorValue = FCKeditorAPI.GetInstance('name_of_editor') ;

you can check if its empty by using this: if(editorValue.EditorDocument.body.innerHTML == "<p> <br> </p>"){
msg += " \n";
}

you use the "

" because by default, it places any value of the editor between the p and br tags.

im sure im saving some people the time it took me to figure it out.
