SyntaxError：输入节点js的意外结束[关闭]答案

【问题标题】：SyntaxError : Unexpected end of input node js [closed]SyntaxError：输入节点js的意外结束[关闭]
【发布时间】：2021-06-17 16:21:59
【问题描述】：

我使用 c9.io 运行这个脚本，我得到这个错误。我试图自己找到错误，但对我来说似乎不可能，因为代码太大，如果有人可以帮助我，我将不胜感激。

错误：

调试器监听 [::]:15454 /home/ubuntu/workspace/server.js:341 }); ^

SyntaxError：输入意外结束在 createScript (vm.js:56:10) 在 Object.runInThisContext (vm.js:97:10) 在 Module._compile (module.js:542:28) 在 Object.Module._extensions..js (module.js:579:10) 在 Module.load (module.js:487:32) 在 tryModuleLoad (module.js:446:12) 在 Function.Module._load (module.js:438:3) 在 Timeout.Module.runMain [as _onTimeout] (module.js:604:10) 在 ontimeout (timers.js:386:14) 在 tryOnTimeout (timers.js:250:5)

【问题讨论】：

你真的应该结合条件来限制高层次的嵌套，深度嵌套使得调试这样的问题变得困难（同时增加了遇到它们的可能性）：if(as==data.secret && ban==0 && credits>=data.amount)
是的，这是真的不要做很多嵌套。您还可以使用辅助函数，例如查找数据是否为数组

标签： javascript jquery node.js

【解决方案1】：

好的 - 我想我找到了。您没有关闭 io.on 功能。尝试添加：

});

就在代码底部的 inArray 函数之前。让我知道这是否能解决问题。

或者它可能就在socket.on('showmssages',function(data) 之前，具体取决于该函数应该关闭的位置。但这肯定是问题所在。

【解决方案2】：

我确信我的错误是因为您的一个牙套没有打开和关闭。尝试查看line 341 of server.js 并尝试将其与左大括号匹配。您不必遍历所有代码。你很快就会找到它。

【讨论】：

第 341 行是最后一行，它是空的
正确 - 这意味着它位于代码深处。我现在正在找它
