Question

我对JSON世界有点新鲜。我必须使用JavaScript来创建以下类型的JSON结构。不知道如何实现这一目标。尝试使用以下代码，但无法将第二个元素（“12101”）以及人员添加到JSON Structure是我正在努力的地方。

var chat = {};
chat = {"101":{}};
chat["101"].people= {};
chat["101"].people = {"L0b12leL-Ar9GYKoAAAC":{}};
chat["101"].people.L0b12leL-Ar9GYKoAAAC = {"name":"vikram@qech.com"};
chat["101"].room= {};

实现JSON结构

    "people": {
      "L0b12leL-Ar9GYKoAAAC": {
        "name": "vikram@qtech.com",

Answer 1

这是无效的，因为属性名称包含破折号。

chat["101"].people.L0b12leL-Ar9GYKoAAAC = {"name":"vikram@qech.com"};

要正确访问它，请将其放在引号

中

chat["101"].people["L0b12leL-Ar9GYKoAAAC"] = {"name":"vikram@qech.com"};

Answer 2

像这样使用bracket notation as a property accessor：

chat["12101"].people = {};
chat["101"].people["L0b12leL-Ar9GYKoAAAC"] = {"name":"vikram@qech.com"};

有了它，它只是一项例行工作。它可能不会立即起作用，因为点符号属性访问需要valid identifier name。使用括号表示法，您可以使用任何字符串，如"L0b12leL-Ar9GYKoAAAC"。

另请注意，在JSON中，任何内容都可以作为属性名称使用，只要它放在引号中即可。 {"L0b12leL-Ar9GYKoAC":true} as valid为{"":true}。
