再会;
我正在继续尝试为 Cardfight 创建套牌构建应用程序！先锋
有一条规则，一副牌不能超过 4 张同一张牌，一副牌不能超过 50 张牌。
我正在努力做到这一点，以便我有一个计数器，当卡片添加到牌组时会增加，当牌从牌组中取出时会减少。但是这个计数器必须针对每张从 0 开始并在每次将具有特定名称的卡添加到套牌时增加 1 的卡。
我有一个 vanguard 对象和数据库数组，可以在其中轻松创建新的 Vanguard 对象。我在 Vanguard 对象 ( this.cardLimit = 0) 中有一个变量，它将最初将每张新卡的卡限制设置为 0。
然后当一张新卡[addToDeck]被添加到卡组中时，它将在数据库中为该特定卡增加一个计数器：database[addToDeck].cardLimit++，直到达到最大值 4，之后这个 if 语句将不起作用：
if (deck.length < 51 && database[addToDeck].cardLimit < 5)
我的问题是 - 正如您将在下面的代码中看到的那样 - 当我使用 jquery 删除卡时，我无法找到减少此值的方法。我所做的是将卡片名称动态添加到 div，当单击该 div 中的卡片名称时，它不仅会从 div 中删除卡片，还会通过拼接从卡组数组中删除卡片。
我不能database[addToDeck].cardLimit--像你在我的代码中看到的那样做，因为我使用 jQuery 和“this”来专门指div被点击的部分。
那么我的问题是....如何根据我迄今为止提供的代码规范减少计数器？当我的用于移除部分牌组的 Jquery（代码中的最后一个 jQuery 实例）运行时，我需要减少已移除的特定卡片的计数器。
如果您需要任何进一步的澄清，请告诉我......我用简单的术语解释我的问题并不容易。非常感谢您的阅读。
