如何从猫鼬的对象数组中获取单个嵌套的对象？

Question

我想从猫鼬的对象的嵌套数组中检索单个对象。我在下面附加了示例json代码。

{
        "_id" : ObjectId("1"),
        "name" : "xxx",
        "votes" : [
                {
                        "actionType" : 11,
                        "voter" : [
                                {
                                        "user" : "john",
                                        "pass" : a 
                                },
                                {
                                        "user" : "david",
                                        "pass" : b
                                }
                        ]
                },
                {
                        "actionType" : 22,
                        "voter" : [
                                {
                                        "user" : "john",
                                        "pass" : c 
                                },
                                {
                                        "user" : "david",
                                        "pass" : d
                                }
                        ]
                }
        ]
}

预期结果为

{
   "user":"john",
   "pass":c
} 

说明：我要使用actionType = 22和user = john的用户对象

`var obj = {};
var votes = response.votes;
votes = response.votes[];
for(var i=0; i<votes.length; i++) {
    if(votes[i].actionTypes === 22) {
        var voter = votes[i].voter;
        for(var i = 0; i<voter.length;i++) {
                if(voter[i].name === 'john') {
                    obj.push(voter[i]);
                    break;
                } 
        }
    }
}
