javascript - Converting a JS object to an array using jQuery

Question

My application creates a JavaScript object, like the following:

myObj= {1:[Array-Data], 2:[Array-Data]}

But I need this object as an array.

array[1]:[Array-Data]
array[2]:[Array-Data]

So I tried to convert this object to an array by iterating with $.each through the object and adding the element to an array:

x=[]
$.each(myObj, function(i,n) {
    x.push(n);});

Is there an better way to convert an object to an array or maybe a function?

Answer 1

If you are looking for a functional approach:

var obj = {1: 11, 2: 22};
var arr = Object.keys(obj).map(function (key) { return obj[key]; });

Results in:

[11, 22]

The same with an ES6 arrow function:

Object.keys(obj).map(key => obj[key])

With ES7 you will be able to use Object.values instead (more information):

var arr = Object.values(obj);

Or if you are already using Underscore/Lo-Dash:

var arr = _.values(obj)
