How do you get a specific value from an object in javascript?

The Object.values() method returns an array of a given object's own enumerable property values, in the same order as that provided by a for...in loop. (The only difference is that a for...in loop enumerates properties in the prototype chain as well.)

Try it

Syntax

Parameters

obj

The object whose enumerable own property values are to be returned.

Return value

An array containing the given object's own enumerable property values.

Description

Object.values() returns an array whose elements are the enumerable property values found on the object. The ordering of the properties is the same as that given by looping over the property values of the object manually.

Examples

Using Object.values

const obj = { foo: 'bar', baz: 42 };
console.log(Object.values(obj)); // ['bar', 42]

// Array-like object
const arrayLikeObj1 = { 0: 'a', 1: 'b', 2: 'c' };
console.log(Object.values(arrayLikeObj1 )); // ['a', 'b', 'c']

// Array-like object with random key ordering
// When using numeric keys, the values are returned in the keys' numerical order
const arrayLikeObj2 = { 100: 'a', 2: 'b', 7: 'c' };
console.log(Object.values(arrayLikeObj2 )); // ['b', 'c', 'a']

// getFoo is property which isn't enumerable
const myObj = Object.create({}, { getFoo: { value() { return this.foo; } } });
myObj.foo = 'bar';
console.log(Object.values(myObj)); // ['bar']

// non-object argument will be coerced to an object
console.log(Object.values('foo')); // ['f', 'o', 'o']

I have this object:

var data = {"id": 1, "second": "abcd"};

These are values from a form. I am passing this to a function for verification.

If the above properties exist we can get their values with data["id"] and data["second"], but sometimes, based on other values, the properties can be different.

How can I get values from data independent of property names?

To access the properties of an object without knowing the names of those properties you can use a for ... in loop:

for(key in data) {
    if(data.hasOwnProperty(key)) {
        var value = data[key];
        //do something with value;
    }
}

In ES2017 you can use Object.values():

Object.values(data)

At the time of writing support is limited (FireFox and Chrome).All major browsers except IE support this now.

In ES2015 you can use this:

Object.keys(data).map(k => data[k])

If you want to do this in a single line, try:

Object.keys(a).map(function(key){return a[key]})

If you $ is defined then You can iterate

var data={"id" : 1, "second" : "abcd"};
$.each(data, function() {
  var key = Object.keys(this)[0];
  var value = this[key];
  //do something with value;
}); 

You can access it by following way If you know the values of keys

data.id

or

data["id"]

I am sorry that your concluding question is not that clear but you are wrong from the very first line. The variable data is an Object not an Array

To access the attributes of an object is pretty easy:

alert(data.second);

But, if this does not completely answer your question, please clarify it and post back.

Thanks !

Using lodash _.values(object)

_.values({"id": 1, "second": "abcd"})

[ 1, 'abcd' ]

lodash includes a whole bunch of other functions to work with arrays, objects, collections, strings, and more that you wish were built into JavaScript (and actually seem to slowly be making their way into the language).

How will you obtain the key value pair from the object?

Use the Object. keys() method to retrieve all of the key names from an object. We can use this method on the above runner object..

Key names must be strings, symbols, or numbers..
Values can be any type..
