纠结了好久，一直没搞定。我正在尝试为此 JSON 中的每条路径创建数组。

真正的最终目标是用 D3 可视化每条路径，但现在我只是想弄清楚如何循环遍历数据并获取所有可能的路径。
输出应该看起来像这样，并考虑到它们可能是相同结构的更多层次。
WebApp : calendar (3151) -> ViewWorkout (521) -> BeginUserSession (12)
WebApp : calendar (3151) -> ViewWorkout (521) -> EditWorkout (134)
...
WebApp : calendar (3151) -> WebApp : athleteLoadedFromLibrary (1230) -> WebApp : calendar (731)
最佳答案
function rKeys(o, path="") {
if (!o || typeof o !== "object") return path;
return Object.keys(o).map(key => rKeys(o[key], path ? [path, key].join(".") : key))
}
const objectPaths = (o) => { return rKeys(o).toString().split(",") }
console.log(objectPaths({x: {y: {z: 1}, g: {a: 1, b: 2}}}))以上输出了一个由 . 分隔的路径列表。你的对象。然后，您可以使用 lodash 的 get 方法访问该值
const foo = {bar: {baz: "foo"}}
_.get(foo, "bar.baz") === "foo" // true
所以 rKeys 的输出很有用
