嵌套 For 循环在 27 项中的 22 项后退出，运行 在节点服务器端
Nested For loop exited after 22 items in 27 items, running on Node server side
[已修改]
这里可以提供一点帮助。
我 运行 遇到了 for 循环的问题。我有一个 for 循环嵌套在另一个中。外层循环只有 level 元素，而嵌套层只包含 27 个项目。
问题是安装程序在退出前只能 运行 通过嵌套数组的 22 项。
在服务器端 运行 设置，在 node.js 中完成。客户端是 React，它通过 websocket 与服务器通信。从控制台报告中，node.js 运行s 上述代码 3x；在所有这些时间里，只有 22 项超出了预期的 27 项。

我用你的数据试过你的代码，正如预期的那样，它遍历了所有 27 个项目。但是因为不满足某些条件，您正在为第 22 条记录设置 innError = true，并且永远不会将其设置回 false。
所以之后的所有项目都将被视为它们也有错误（这可能会让您相信它们没有被迭代）。只需尝试在内部循环中添加一个 console.log(j) 作为第一个语句。你会看到，它会打印出从 0 到 26 ...
的所有值
[已修改] 这里可以提供一点帮助。 我 运行 遇到了 for 循环的问题。我有一个 for 循环嵌套在另一个中。外层循环只有 level 元素，而嵌套层只包含 27 个项目。 问题是安装程序在退出前只能 运行 通过嵌套数组的 22 项。

我用你的数据试过你的代码，正如预期的那样，它遍历了所有 27 个项目。但是因为不满足某些条件，您正在为第 22 条记录设置 innError = true，并且永远不会将其设置回 false。
所以之后的所有项目都将被视为它们也有错误（这可能会让您相信它们没有被迭代）。只需尝试在内部循环中添加一个 console.log(j) 作为第一个语句。你会看到，它会打印出从 0 到 26 ...
