所以我有一个很长的代码，但是当我运行它时，我收到错误： ＆＃34;解析错误：语法错误，意外的文件结束＆＃34;
我用谷歌搜索了一下，在我看来，最常见的罪魁祸首是错过了一个支架。好吧，我认为这里的问题也是如此。但请允许我详细说明一下：
在我在线获取代码之前，这里是我的代码的简要概述：
这是我认为导致错误的有趣事情。所以在主循环中还有另外两个for循环，我将其命名为二级和三级循环。如果我为主循环放置结束括号（a＆＃34;}＆＃34;）在第三个循环开始之前，主循环的起始括号和结束括号连接（意味着，如果你单击其中一个括号，两者都会点亮绿色，因此它们连接）。但是，如果我在三级循环开始后放置结束括号，主循环的起始括号将不会与它连接。如果我在次级回路之前切断三级回路（从而使次级回路成为次级回路，反之亦然）并不重要，如果主回路的末端支架放置在后，则它将不会与起始支架连接。三级（第三）循环。
我已经多次查看过我的代码了。除了这两个支架外，所有其他支架相互连接。我没有看到任何单独的括号。也许它是某种内部错误，它应该在理论上起作用，但它实际上并不存在。坦率地说，我不是编程天才，所以我在这里发布这个问题：P。
这里是代码（我必须将它放在JavaScript / HTML / CSS片段预览中，因为＆＃34;代码示例＆＃34;混淆了文本，因为它认为每个括号都是新的代码示例）：
