我有这个变量（我相信它是json）。然后，我尝试使用JSON.parse（）将其传递给对象，该对象只是破坏脚本的执行。考虑到整个链以单引号开头和结尾，因此我删除了单引号，但这并不能解决问题。 在此在线工具（http://json.parser.online.fr/）中，变量正常转换。 有什么建议可以锁定此脚本并阻止将变量转换为对象？

答案 0 :(得分：1)
我看到两个单独的问题（在下面的@melpomene指出我错过了第一个问题之后！）：
请通过将其粘贴到（例如）Visual Studio Code中并将其保存为“ test.js”来进行验证。
这里是使用稍微简单一些的JSON文本示例的说明。
您不是在创建您想创建的继承体系，而是在创建8-）
您认为您要在c的{{1}}子项的b子项中放置某些内容，但实际上您是在{{1 }} a的子级。
看看这个：
b.c没有a这样的东西，因此您无法读取其属性a={"b.c":10}
console.log(a)
Result -> {b.c: 10}
a.b.c
Result -> * Error * cannot read property 'c' of undefined
。
相反，您必须阅读以下内容：
a.b您要达到的极限不是长度极限，而是表现力。您无法通过这种方式直接设置属性c及其子项a["b.c"]
Result -> 10
：
dates按如下所示重新构建JSON文本：
{“设置”：{“日期”：{“格式”：“ yyyy-MM-dd”，“语言环境”：“ en_US” .....}}}
或者，如果那样做太多，并且您完全控制了从format读取的软件，则可以保持JSON不变，而是着重读取此处的项目：
警报（obj.settings [“ dates.format”]）
，甚至为了使其在阅读时对自己的未来更加明显，请始终使用{ "settings": { "dates.format": "xxx" }}
表示法。这是Python中使用的格式，也可以在Javascript中使用：
提醒（obj [“ settings”] [“ dates.format”]）
答案 1 :(得分：-1)
let obj = {
name: "Mark",
surname: "Minerov"
};
let object = JSON.stringify(obj);
console.log(object); // {"name":"Mark","surname":"Minerov"}
let parsedObject = JSON.parse(object);
console.log(parsedObject); //normal object
尝试一下，我认为它将为您提供帮助。
