// Events data 
// public/javascripts/events.js 


var mongo = require('mongodb'); 
var monk = require('monk'); 
var db = monk('localhost:27017/soundevents'); 
var eventcollection = db.get('event'); 


var myEvents = eventcollection.find({}, {limit:1}, function(err, docs){}); 
var eventName = myEvents.docs.EventName; 


module.exports.myEvents = myEvents; 
module.exports.eventName = eventName;

要与正在使用的查找和使用one..better的findOne..Something像

var myEvents = eventcollection.findOne(query, [fields, [options]], callback); 

的限制开始如果没有标准，你正在寻找匹配，您可以查询空白太。

其次，find会返回一个游标/匹配结果列表。如果您需要访问使用中找到文档的属性，其中一个方法可以

var eventName = myEvents[0].EventName; 

，或者你可以通过正常的走了，因为/ foreach循环，然后得到的值。
