javascript - 如何检查一个对象中的所有数字是否在某个范围内？

Question

我想在我当前的 JS/jQuery 项目中包含的功能之一是允许用户导出和导入他们保存的数据。导入/导出数据只是通过 JSON.stringify 和 JSON.parse 运行的一个大对象，并且实现其基本版本效果很好，但我想验证导入的数据以确保它能够工作(这与其说是像 JavaScript 一样工作，不如说是在我正在制作的游戏规则范围内工作)。

我想提出一个更有效的脚本来验证这个大而复杂的对象。我关心的对象的唯一部分是数字，但它也包括字符串、数组、嵌套对象。一些嵌套对象包括我关心的数字，但也有更多其他垃圾，包括进一步的嵌套对象。目前，我使用 jQuery 的each() 函数来循环对象的每个子部分并对其进行评估，但这需要我为我关心的每个子部分编写一个each 函数。

如何为整个对象提供函数并让它仅查看数字以查看它们是否大于或小于设定值？

编辑:将对象粘贴到此处，目标是检查是否所有数字。有些需要在 0 到 3 之间，有些需要在 0 到 9 之间。

下面使用递归来搜索多维对象中的所有键，以查找小于或大于所提供数字的任何数字。

只需调用 checkObject(myStuff, 30, 60); 等函数，传入您的对象、允许的最低数量和允许的最高数量
