javascript - Onclick 如何在 mongodb 中查找和更新投票？

Question

我正在创建一个投票系统，但我似乎无法找到一种方法来做我想做的事情（或者我正在寻找错误的事情）。基本上我正在尝试点击甚至触发此代码，而不是使用我的虚拟代码

{"_id": ObjectId("5b7b67247a3b516f8cb0c7d9")}

我希望它从我单击的那个中获取 ObjectId。我应该将其分配给 HTML 中的 ID 吗？

upvote: function(req, res, next){
    let userId = db.get().collection('users').findOne({"_id": ObjectId("5b6a39ff17e9af6c20b9c5a8")});
    let gameId = db.get().collection('matches').findOne({"_id": ObjectId("5b7b67247a3b516f8cb0c7d9")});

    userId.then(function(upvotedata){
        if(upvotedata){
            db.get().collection('matches').updateOne({"_id": ObjectId("5b7b67247a3b516f8cb0c7d9")}, { "$inc": { "currentvote": 1}});
            res.status(200).json();

        } else {
            return res.sendStatus(400);
        }
    });
    gameId.then(function(game){
        if(game){
        } else {
            return res.sendStatus(400);
        }
    });
},
