Encapsulates the JSON data, and for the code to be clear, this approach doesn't work.
/* Seems to be because the array format is not correct.
var datastr=jsondata ();
alert (DATASTR);
*/

var jsonstr= "";
jsonstr+= "\" name\ ":";
jsonstr+= "\" Tree\ "";
jsonstr+= ",";
jsonstr+= "\" id\ ":";
jsonstr+= "\" 123\ "";
jsonstr+= "}";
return jsonstr;
}
