【问题描述】：
我目前的项目有很多代码，所以我会尽力解释我遇到的非常奇怪的问题。
我有一个名为 proDatabase 的数组数组，长度为 126 个条目，每个条目是一个长度为 4 个条目的数组。
我有一个按钮，单击该按钮后，每1.05 秒启动一个setInterval 函数以运行一个名为“getScore”的函数
getScore 包含对 API 的 ajax 调用，该 API 返回一个 JSON 对象，我从该对象收集了一堆数据，然后执行名为 calculateHmc 的计算函数。
calculateHmc 执行大计算并将值推送到全局数组。控制台然后记录这个数组的值以表明它是成功的。
我遇到的问题是，当我运行这个脚本大约需要 2.5 分钟（126 个条目 x 每个条目约 1.05 秒）时，结果会随着运行而变化。我的意思是，有时它会成功获取条目 5、6、7、8、9 的数组，但不会成功获取 10 和 11，而另一次它会获取 5、7、8、10、11 的数组，但不是 6 和 9。
我想也许是我进行 AJAX 调用的速度太快了，但我尝试将延迟设置为 2-5 甚至 9 秒，但问题仍然存在。
我最初使用带有 setTimeout 延迟的 for 循环并更改为 setInterval，因为我认为它可能更适合进行 AJAX 调用。
这是肉和土豆：

这是我的控制台输出，用于成功输入数组。在这里你可以看到它在counter == 9 时获取并推送一个数组。：
这是一个示例，说明它出于某种随机原因跳过此操作：
这两次运行之间没有代码更改。我所做的只是刷新页面并再次单击sendButton。
我意识到有很多东西需要吸收，但我不想简化我的代码并意外排除可能是问题的东西，因为我真的不知道为什么会发生这种情况。
非常感谢您的帮助！
【问题讨论】：
-
您必须等待
getScore完成才能更新计数器，尝试使用回调或承诺 -
那里有很多代码需要查看，但我建议的一件事是使用 setTimeout 而不是 setInterval。然而，不是仅仅将 setTimeouts 放在一个 for 循环中，而是在执行所有其他数据处理功能之后，让 setTimeout 的回调和 ajax 调用创建下一个。这样，各种超时/ajax 函数就不可能重叠。这样做的缺点是您可能会发现 ajax 调用之间的时间不是 100% 正常的，但我认为它对于您的目的来说已经足够接近了。
-
@charlietfl 我相信我确实展示了间隔循环和 ajax 调用，只需查看数组下方。
-
@RodrigoAssis 谢谢你，我会看看这些是什么。保罗也谢谢你，我需要看看回调是什么。
-
当函数不接受任何参数时，为什么要将
counter作为附加参数传递给setInterval？
