如何在Mongodb Node.js中创建和插入数组

Question

现在我的json是这样的：

{
        "_id" = 53a8a41c360ce27c26c374f1;
        eDate = "2014-06-05 16:10";
        eDesc = "Pay \U00a350";
        eEvent = "Victoria Center";
        eLink = "http://linkedin.com";
        eTitle = "Free movies";
    },
        {
        "_id" = 53a8a41f360ce27c26c374f2;
        eDate = "2014-06-05 16:10";
        eDesc = "Pay \U00a350";
        eEvent = "Victoria Center";
        eLink = "http://linkedin.com";
        eTitle = "Free movies";
    }

但是，我想将所有这些放在一个数组中，如下所示：

"eventList": [
       {
        "_id" = 53a8a41c360ce27c26c374f1;
        eDate = "2014-06-05 16:10";
        eDesc = "Pay \U00a350";
        eEvent = "Victoria Center";
        eLink = "http://linkedin.com";
        eTitle = "Free movies";
    },
        {
        "_id" = 53a8a41f360ce27c26c374f2;
        eDate = "2014-06-05 16:10";
        eDesc = "Pay \U00a350";
        eEvent = "Victoria Center";
        eLink = "http://linkedin.com";
        eTitle = "Free movies";
    }
]

这就是我插入数据库的方式：

 // Set our collection
    var collection = db.get('Events');

    // Submit to the DB
    collection.insert({
        "eTitle" : eTitle,
        "eDesc" : eDesc,
        "eDate" : eDate,
        "eLink" : eLink,
        "eEvent" : eEvent
    }, function (err, doc) {
        if (err) {
            // If it failed, return error
            res.send("There was a problem adding the information to the database.");
        }
        else {

            res.location("eventlist");
            // And forward to success page
            res.redirect("eventlist");
        }
    });

请问我该如何解决这个问题？抱歉，对于node.js和mongodb来说非常棒！非常感谢
