Javascript如何在下面的代码中获取属性

Question

code

当我尝试将其作为 code.attrs 或 code["attrs"] 时，它返回未定义的值 如果您有任何想法，请随时告诉我，我已经为此工作了好几个小时。

[
  <ref *1> SoupTag {
    parent: SoupTag {
      parent: [SoupTag],
      previousElement: [SoupString],
      nextElement: [SoupString],
      name: 'div',
      contents: [Array],
      attrs: [Object],
      hidden: false,
      builder: [TreeBuilder]
    },
    previousElement: SoupString {
      parent: [SoupTag],
      previousElement: [SoupComment],
      nextElement: [Circular *1],
      _text: '     \n                    \n                    \n                    '
    },
    nextElement: SoupString {
      previousElement: [Circular *1],
      nextElement: [SoupComment],
      _text: '\n                    \n\n                    '
    },
    name: 'img',
    contents: [],
    attrs: {
      src: 'https://img-c.udemycdn.com/course/750x422/4008038_0a54.jpg',

如果我正确理解阻尼数据结构的 sn-p，code 是一个包含一个对象的数组。如果您需要此对象的attr 属性，请尝试code[0].attrs。
