我在从 JSON 获取值时遇到问题，该值在键名中包含 space。我正在使用 JavaScript 来获取值，但如果密钥包含 space（与死亡擦肩而过）或者它是一个数字 (6)，我将无法使其工作。
有什么办法可以不编辑 JSON 文件吗？
提前致谢。 :)
有两种访问属性的方法；
foo.bar foo['bar']
你需要使用第二个选项来使用空格，例如foo['bar bar'].baz

我在从 JSON 获取值时遇到问题，该值在键名中包含 space。我正在使用 JavaScript 来获取值，但如果密钥包含 space（与死亡擦肩而过）或者它是一个数字 (6)，我将无法使其工作。
有什么办法可以不编辑 JSON 文件吗？
提前致谢。 :)
有两种访问属性的方法；
foo.barfoo['bar']
你需要使用第二个选项来使用空格，例如foo['bar bar'].baz
