用随机对象填充对象，并在 javascript 中设置特定属性答案

【问题标题】：Populate a Object with random Objects, and setting specific properties in javascript用随机对象填充对象，并在 javascript 中设置特定属性

【问题描述】：

我正在使用 NodeJS 和 socket.io 创建一个在线浏览器纸牌游戏。

我在底部编写了代码，其中一个对象填充了两个玩家（0 和 1），然后每个玩家都得到一个持有牌组的对象，其中还有两个对象，即以对象的形式持有卡片。

userlists: { // I have more than just "g" in here, but for this part, only "g" is needed
    "g": { // Holds the different game-sessions
        "roomid": { // A Game-Session
            "Players": { // Contains the 2 Opponents
                0: { // Opponent 1
                    "deck": { // The deck of Opponent 1 (note that the different decks are no objects, though if needed, they could be)
                        "onHand": [ // Contains all the Cards "on-Hand"
                            {
                                "Type": "Knight",
                                ... // more properties
                                "position": 0 // The position of the Card on the hand of the Player
                            },
                            ... // more Cards
                        ],
                        "inBlock": [ // Contains all the reserve-Cards
                            ... // as in ["onHand"], but with ["position"]=null
                        ]
                    }
                },
                1: { // Opponent 2
                    ... // same as Opponent 1, just different deck of course
                }
            }
        }
    }
}

但由于这是一个问题，下面的代码实际上并没有产生预期的结果。实际上，它首先会输出所需的数字，但随后，在它被发送（function snddcks()）到客户端的位置，"position"（实际上也是所有其他属性），被复制了一些"Type"，所以所有"Type":"Knight" 都会有"position":0 等等。

这就是问题所在，我无法弄清楚它为什么会发生。

最后，我将快速解释一下过程：

嗯，首先，加入的玩家（NR 1，而不是 0）在userlists["g"][roomid] 中创建游戏会话对象（服务器端），其中 roomid 是随机生成的字符串李>
NR1，然后告诉 NR0 他已经加入，然后 NR0 将“playerhasjoined”发回服务器
然后在服务器端调用函数“populateDeck”，然后填充卡片组，首先是 NR0，然后是 NR1
最后，调用“snddcks”，然后将所有数据发送到两个客户端

所以在第 3 步中，所有“位置”和其他属性都已正确设置，但在第 4 步中，它们会被任何内容覆盖。

这是新代码：

function joingid() {
    var roomid = userlists["eo"][socket.username]["gid"];

    socket.state = "playing";
    socket.join(roomid);
    socket.leave("lobby");
    socket.leave("searching");

    socket.emit("playerfound", {
        gid: roomid
    });
    socket.broadcast.to(roomid).emit('playerjoined', {
        usr: socket.username,
        gid: roomid
    });
}
socket.on('playerhasjoined', function(data) {
    socket.state = "playing";
    socket.leave("lobby");

    var roomid = userlists["eo"][socket.username]["gid"];

    socket.broadcast.to(roomid).emit('otheropponent', {
        usr: socket.username
    });

    setTimeout(function() {
        populateDeck2(roomid, data["oppo"]);
    }, 500);
});

【问题讨论】：

服务器端需要什么超时？你为什么要递归迭代？
据我了解，NodeJS 几乎完全是异步的。另外，（我不太记得）超时是实际需要的地方，因为客户端不会在其他人之前收到特定数据..
它是运行时环境中带有一些库的 JS。只是不在浏览器中。没有理由为微不足道的迭代提供函数......尝试重写你的循环。并且不要在方法调用之前使用超时。没有意义。仅当您需要等待非阻塞源并估计阈值时。但这会很危险......
@LemmyTauer 然后你会推荐我，使用 for 或 while 循环，还是有另一种更清洁的方法？因为loop5 和6 实际上是不需要的，但我只是将它们放入snddcks 中，以测试它是否真的改变了什么。但显然它没有......而且，所有这些代码实际上都是服务器端的，所以它是 NodeJS，当你只是谷歌“node js async 吗？”时，你会得到很多结果，指出 Node 的异步自然。还是我还是在这里搞错了！？
使用 for 循环并注意您创建的闭包，因此可能会更改数据的“本地范围”副本......因此，要么在调用期间通过将其传递给函数范围来保存（需要一些更多地了解闭包）或尽量避免与回调嵌套过多...

【解决方案1】：

终于！！我刚刚解决了我的问题，虽然我花了 3 天的时间.. 非常感谢@LemmyTauer 提供帮助的 cmets :)

这是有趣的代码部分：

function generatedeckthigieandreturn(number) {
    var arr;
    arr = [];
    var fncs;
    fncs = [];
    var ARRAYTHINGIEd = [];

    function gRC() {
        console.log("gRC called");
        return standardDeckCards[Math.floor(Math.random() * standardDeckCards.length)];
    }

    for (var a = 0; a < number; a++) {
        console.log(a);
        fncs[a] = function(b) {
            console.log(a+" called");
            return function() {
                arr[b] = gRC();
                arr[b]["position"] = b;
                arr[b]["CID"] = "CID-"+(Math.floor((Math.random() * 900) + 100)).toString();
                console.log(JSON.stringify(arr[b], null, 4));
                return JSON.stringify(arr[b]);
            }
        };
    }
    for (var c = 0; c < number; c++) {
        ARRAYTHINGIEd.push(JSON.parse(fncs[c](c)()));
    }
    return ARRAYTHINGIEd;
}
for (var xa = 0; xa < 2; xa++) {
    userlists["g"][roomid]["Players"][xa]["deck"]["onHand"] = generatedeckthigieandreturn(5);
    userlists["g"][roomid]["Players"][xa]["deck"]["inBlock"] = generatedeckthigieandreturn(50);
}

所以最后，我使用JSON.stringify() 来保留 Card-Object，并使用JSON.parse() 将其恢复为“正常”格式。

这是“完整的固定问题”-代码：

function joingid() {
    var roomid = userlists["eo"][socket.username]["gid"];

    socket.state = "playing";
    socket.join(roomid);
    socket.leave("lobby");
    socket.leave("searching");

    socket.emit("playerfound", {
        gid: roomid
    });
    socket.broadcast.to(roomid).emit('playerjoined', {
        usr: socket.username,
        gid: roomid
    });
}
socket.on('playerhasjoined', function(data) {
    socket.state = "playing";
    socket.leave("lobby");

    var roomid = userlists["eo"][socket.username]["gid"];

    socket.broadcast.to(roomid).emit('otheropponent', {
        usr: socket.username
    });

    setTimeout(function() {
        populateDeck2(roomid, data["oppo"]);
    }, 500);
});


function populateDeck2(roomid, oppo) {
