查找嵌套对象的键并返回其路径 [英] Find key of nested object and return its path

问题描述

有人知道一个好的javascript npm包(或具有一些好的功能)来查找JSON密钥并返回其路径(或路径(如果密钥在嵌套JSON中不止一次存在))

Does anyone know a good javascript npm package (or have some good function) to find a JSON key and return its path (or paths if key exists more than once in nested JSON)

for example:
var person={
"name":myName,
"address":{
"city",
"location":{
"long":123,
"lat":456
}
"long"

我想使用一个函数，该函数将返回此键的路径，在上面的示例中，键"long"存在两次:

I want to use a function that will return the path to this key, in above example the key "long" exist twice:

console.log(getKeyPath(person,"long"); //address.long，long

console.log(getKeyPath(person,"long"); //address.long , long

推荐答案

使用 obj-flatten 您可以将其制成平面对象:

Using obj-flatten you can make that a flat object:

var person = {
  "name": "your name"
  "location.long": 123,
  "location.lat": 456,
  "long": 42,
  ...
}

然后您只需要按该模式查询即可:

And then you simply have to query by that pattern:

var searchKey = "long";
var yourKeys = Object.keys(person).filter(function (c) {
   return c.split(".").indexOf(searchKey) !== -1;
});
// => ["location.long", "long"]
