Finding a key in json
-1
I have the following json:
let object = {
"statusCode": 200,
"body": [{
"id": "3",
"externalId": "billgates",
"status": "active",
"createdAt": "2018-11-14T08:36:50.967Z",
"updatedAt": "2018-11-14T08:36:50.967Z",
"firstName": "yehu",
"lastName": "da",
"email": "bg@g.com"
}
],
"headers": {
"x-powered-by": "Express",
"access-control-allow-origin": "*",
"content-type": "application/json; charset=utf-8",
"content-length": "189",
"etag": "W/"bd-Emx3/KChQLzf9+6bgFSHXPQgDTM"",
"date": "<<Masked>>",
"connection": "close"
},
"request": {
"uri": {
"protocol": "http:",
"slashes": true,
"auth": null,
"host": "mysite",
"port": "4202",
"hostname": "mysite",
"hash": null,
"search": "?username=billgates",
"query": "username=billgates",
"pathname": "/v1/users",
"path": "/v1/users?username=billgates",
"href": "http://mysite"
},
"method": "GET",
"headers": {
"Content-Type": "application/json",
"accept": "application/json",
"content-length": 2
}
}
}
i wrote a function that gets a key and a value and if key with that value found in json returns true otherwise false, here is the function:
let key = "externalId";
let value = "bilgates"
let findValue = function findValue(obj, key, value) {
for(let localKey in obj){
if(obj.hasOwnProperty(localKey)){
if(localKey === key){
res = obj[localKey] === value;
return res;
}
else{
let val = obj[localKey];
findValue(val, key, value);
}
}
}
}
let res = findValue(object, key, value)
console.log(res);
after running the function in VS Code (node.js) I get the following error:
RangeError: Maximum call stack size exceeded
after debugging the function, I could not found the problem. It seems that after some point, localKey will be always zero and obj[localKey] will be always 3.

hint ... it's"id": "3",that is causing the problem (you need to check ifobj[localKey]is an actual OBJECT before recursing ...you'll also need to recurse PROPERLY - because unless the key is found in the top level, you'll always get undefined once you fix your infinite recursion

Note that if you're dealing with a plain object without a meaningful internal prototype, thehasOwnPropertycheck is superfluous. (or just useObject.keys/entriesinstead, which only iterate over properties directly on the object)

Though a different solution, still you can try below approach
let object = {

"body": [{
"id": "3",
"externalId": "billgates",
"status": "active",
"createdAt": "2018-11-14T08:36:50.967Z",
"updatedAt": "2018-11-14T08:36:50.967Z",
"firstName": "yehu",
"lastName": "da",
"email": "bg@g.com"
}
],

"x-powered-by": "Express",

function findValue(obj, k, v) {
let res = false

hint ... it's
"id": "3",that is causing the problem (you need to check ifobj[localKey]is an actual OBJECT before recursing ...you'll also need to recurse PROPERLY - because unless the key is found in the top level, you'll always get undefined once you fix your infinite recursion– Bravo

Note that if you're dealing with a plain object without a meaningful internal prototype, the
hasOwnPropertycheck is superfluous. (or just useObject.keys/entriesinstead, which only iterate over properties directly on the object)– CertainPerformance

quickest fix for your code pastebin.com/8YQb4mQ3 - but I wouldn't do it this way at all

@Bravo why you wouldn't do it this way. whats wrong with it?
