I want to write a function where given a code value it gives me back the full path. is there any arrays package with mæde function for this purpose I tried the npm array-tools but no success a.where(json, { "id": idValue }) is giving an empty array, that I was hoping to show recursively.

what I need looks like

searchPath(array,"003") ==> "003,rtsp,parent"

• Aluan Haddad: That's not an array
• Mister Jojo: I do not think that it exists, the structure of objects are by nature very varied. they must be written case by case

Answer 1

Very similar task. You just should to save all your path and return this path when you find value (key)

Answer 2

1.flatten object 2. get keys 3. find key

const flatten = (obj, prefix = '', res = {}) => 
 Object.entries(obj).reduce((r, [key, val]) => {
 const k = `${prefix}${key}`
 if(typeof val === 'object'){ 
 flatten(val, `${k}.`, r)
 } else {
 res[k] = val
 }
 return r
 }, res)
const flattendObj = flatten(obj);
const found_path = Object.keys(falttendObj).find(key => key === match)

Answer 3

thank you for your answers it helped me learning something, however here is my solution that fits perfectly my needs

function getCamPath(idValue) {
 console.log("++++++++++++++++" + idValue);
 found_path = "";
 var path = "zone -";
 function search(path, obj, target) {
 var found = false;
 for (var k in obj) {
 if (obj.hasOwnProperty(k))
 if (obj[k] === target){
 value = obj.code 
 if(value)
 return path + "-" + value+ "-"
 else return path;
 }
 else if (typeof obj[k] === "object") {
 value = obj.code
 var result 
 if(value)
 result = search(path + "-" + obj.code + "-", obj[k], target);
 else result = search(path , obj[k], target);
 if (result)
 return result;
 }
 }
 return false;
 }
 var path = search(path,json,idValue);
 console.log("++++++++++++++++" + path);
 return path;
}
