function getRandomName(namesList, callback) { var realname = ""; client.get('userlist’, function (error, res) { var list = JSON.parse(res); var pos = Math.round(Math.random() * (list.length - 1)); var oo = list[pos]; realname = "[" + oo.user_code + "]" + oo.real_name; return callback(realname); }); };
