find value in complex object javascript

Basically I have a complex object that retrieves the GPT API (google publisher tag) with this function:
googletag.pubads().getSlots();
The object value is something like this:
I need to know if there is a way to compare the value of each property with an X value without getting a problem of recursivity (because the object is huge and i need to to that validation several times)
Also, I tried to convert that object into a JSON with JSON.stringify(), and then tried to get the value with a regex, faster, but with this option, I have the problem with Cyclic Object Value.
Any suggestions ?

it's more simple. try it to convert it into an array and later use a filter for comparative with your value.
var objGoogle = {};
var arrayObjectGoogle = [objGoogle];
var filter = arrayObjectGoogle.filter(function(obj){
obj.yourAttr == yourValue; });
this will give you a second array with the values found it. later, index the array for pick up the value do you need.

Cant access single object in array?

Hi I am having problems with accessing Object in array... I dont know is it because i updated Chrome or because i added, and after removed Preact from my React application. Problem is this:
Tags is array of objects:
var fullTag = tags.filter(tag => tag.tagId==tagId);
console.log(fullTag);
And as a result i get this in console:
[{…}]
When i expand it i get this:(image)
So there's no way to access it except with
console.log(Object(fullTag[0]).tag);
In all other ways i get undefined... Why is this?! I can swear that i could access it with fullTag.tag until yesterday... Can someone explain me please?

The filter() method creates a new array with all elements that pass the test implemented by the provided callback function.
So, after you filter an array, you will obtain another array even if there is only one item which pass the test function. That's why you couldn't access it using fullTag.tag.
Solution is to access one element using its index.
let tags=[{"id":1,"tag":"tag1"},{"id":2,"tag":"tag2"}];
let tagId=1;
var fullTag = tags.filter(tag => tag.id==tagId);
console.log(fullTag);
console.log(Object(fullTag[0]).tag);
If tagId property is unique in your array you can use find method.
var fullTag = tags.find(tag => tag.id==tagId);
Now you can access your tag property in that way you wished.
console.log(fullTag.tag);

Read a HashMap in App Script

I try to read my data on a Hash Table but I search in the internet but i don't find a solution.
KPIs.push( {name: [data[0][j]], unite :[data[1][j]], order: [data[2][j]], column:[j] , area:[getArea(data[0][j])] } ) ;
I try :
KPIs.value["name"] // doesn't work
KPIs.length // work
How can I read this HashTable ?
Thanks for your help.

Based on your code it appears you are pushing an Object onto an Array, but you attempt to access the object properties directly on the Array, rather than on the element in the Array.
You'll first need to access the correct Array element, before attempting to access your object properties:
KPIs[0].name
or, to loop over them:
for(var i in KPIs){
var name = KPIs[i].name;
Logger.log(name);
}

Get Value of Child Object with JavaScript

I have a JSON collection produced from an object graph. Shown below is an example value. I am having trouble accessing the nested 'Type' object to retrieve any of it's values.
[{"Id":1,"Name":"My Name","Type":{"Id":1,"Name":"my Value"}}]
I am using a JS component that has a property that can be assigned a value similar to below.
myProperty: Type.Name, //Not working
Can someone recommend how I set this value?

What you have is a JavaScript array, not an object, and certainly not JSON. So if you have
var arr = [{"Id":1,"Name":"My Name","Type":{"Id":1,"Name":"my Value"}}]
you'd need to index it, and grab the Type object off of that.
var typeName = arr[0].Type.Name;

Javascript pushing objects into array changes entire array

I'm using a specific game making framework but I think the question applies to javascript
I was trying to make a narration script so the player can see "The orc hits you." at the bottom of his screen. I wanted to show the last 4 messages at one time and possibly allow the player to look back to see 30-50 messages in a log if they want. To do this I set up and object and an array to push the objects into.
So I set up some variables like this initially...
servermessage: {"color1":"yellow", "color2":"white", "message1":"", "message2":""},
servermessagelist: new Array(),
and when I use this command (below) multiple times with different data called by an event by manipulating servermessage.color1 ... .message1 etc...
servermessagelist.push(servermessage)
it overwrites the entire array with copies of that data... any idea why or what I can do about it.
So if I push color1 "RED" and message1 "Rover".. the data is correct then if I push
color1"yellow" and message1 "Bus" the data is two copies of .color1:"yellow" .message1:"Bus"

When you push servermessage into servermessagelist you're really (more or less) pushing a reference to that object. So any changes made to servermessage are reflected everywhere you have a reference to it. It sounds like what you want to do is push a clone of the object into the list.
Declare a function as follows:
function cloneMessage(servermessage) {
var clone ={};
for( var key in servermessage ){
if(servermessage.hasOwnProperty(key)) //ensure not adding inherited props
clone[key]=servermessage[key];
}
return clone;
}
Then everytime you want to push a message into the list do:
servermessagelist.push( cloneMessage(servermessage) );

When you add the object to the array, it's only a reference to the object that is added. The object is not copied by adding it to the array. So, when you later change the object and add it to the array again, you just have an array with several references to the same object.
Create a new object for each addition to the array:
servermessage = {"color1":"yellow", "color2":"white", "message1":"", "message2":""};
servermessagelist.push(servermessage);
servermessage = {"color1":"green", "color2":"red", "message1":"", "message2":"nice work"};
servermessagelist.push(servermessage);

There are two ways to use deep copy the object before pushing it into the array.
1. create new object by object method and then push it.
servermessagelist = [];
servermessagelist.push(Object.assign({}, servermessage));
Create an new reference of object by JSON stringigy method and push it with parse method.
servermessagelist = [];
servermessagelist.push(JSON.parse(JSON.stringify(servermessage));
This method is useful for nested objects.

servermessagelist: new Array() empties the array every time it's executed. Only execute that code once when you originally initialize the array.

I also had same issue. I had bit complex object that I was pushing in to the array. What I did; I Convert JSON object as String using JSON.stringify() and push in to the Array.
When it is returning from the array I just convert that String to JSON object using JSON.parse().
This is working fine for me though it is bit far more round solution.
Post here If you guys having alternative options

I do not know why a JSON way of doing this has not been suggested yet.
You can first stringify the object and then parse it again to get a copy of the object.
let uniqueArr = [];
let referencesArr = [];
let obj = {a: 1, b:2};
uniqueArr.push(JSON.parse(JSON.stringify(obj)));
referencesArr.push(obj);
obj.a = 3;
obj.c = 5;
uniqueArr.push(JSON.parse(JSON.stringify(obj)));
referencesArr.push(obj);
//You can see the differences in the console logs
console.log(uniqueArr);
console.log(referencesArr);

This solution also work on the object containing nested keys.
Before pushing, stringify the obj by
JSON.stringify(obj)
And when you are using, parse by
JSON.parse(obj);

As mentioned multiple times above, the easiest way of doing this would be making it a string and converting it back to JSON Object.
this.<JSONObjectArray>.push(JSON.parse(JSON.stringify(<JSONObject>)));
Works like a charm.
