   function checkFCK(key)
   {
        var oEditor=FCKeditorAPI.GetInstance(key);
        var content=oEditor.GetXHTML(true);
        content=content.replace(/　/g,"");
        content=content.replace(/\s/g,"");
        content=content.replace(/ /g,"");
        content=content.replace(/<br\/>/g,"");
        content=content.replace(/<p><\/p>/g,"");
        content=content.replace(/<div><\/div>/g,"");
        if(content==null||content==""){
            oEditor.SetHTML("");
            return false;
        }
        return true;
   }
形式2：
    function GetMessageLength(str)
    {
        var oEditor = FCKeditorAPI.GetInstance(str) ;
        var oDOM = oEditor.EditorDocument ;
        var iLength ;
        if ( document.all ) // If Internet Explorer.
        {
            iLength = oDOM.body.innerText.length ;
        }
        else // If Gecko.
        {
            var r = oDOM.createRange() ;
            r.selectNodeContents( oDOM.body ) ;
            iLength = r.toString().length ;
        }
            return iLength
    }
