This question already has an answer here:

I have a JSON array and I am trying to sort it by value. The problem I am having is that I am not able to keep the JSON structure with my sorting.

Here is the JSON array:

{
  caffeineoverdose: '2517',
  workhardplayhard: '761277',
  familia: '4633452'
}

I would like something like this:

{
  familia: '4633452',
  workhardplayhard: '761277',
  caffeineoverdose: '2517
}

Either you have a string in JSON format, an array, or most likely a regular javascript object? Which one is it ? –  adeneo Jan 7 at 16:55

It's not an array. It's an object. –  Eimantas Jan 7 at 16:55

you can't sort an object... but you can create a function and put that values into an array .. then sort. –  cocco Jan 7 at 16:56

First off, there is no such thing as a "JSON array". JSON is a string representation of data (like XML or CSV). If it's not a string, it's not JSON. Second, this would be a JavaScript object (not an array). Objects can not be sorted in JavaScript, only arrays can. You want your data to be in an array, such as: [{familia: '4633452'}, {...}]. then you can sort it. –  Rocket Hazmat Jan 7 at 16:57

Those are JavaScript object literals, the syntax is invalid for JSON. –  Quentin Jan 7 at 16:57

Here is everything you need.

Like i said already in the comments you can't sort an object.. but you can put it into an array and display the results.

var array=[],obj={
 caffeineoverdose:'2517',
 workhardplayhard:'761277',
 familia:'4633452'
};
for(a in obj){
 array.push([a,obj[a]])
}
array.sort(function(a,b){return a[1] - b[1]});
array.reverse();

THIS WORKED! THANKS :) –  basic1point0 Jan 7 at 17:34
    
Instead of using array.reverse(), you can just change the sort function to b[1] - a[1]. –  Rocket Hazmat Jan 7 at 17:40

That's not JSON, and it's not an array. It's a regular JavaScript object, and you cannot impose an ordering on the properties of an object.

If you want to maintain the order of your elements, you need an array (again, this isn't JSON, it is JavaScript):

[ [ 'familia', '4633452'] ,
  [ 'workhardplayhard', '761277'],
  [ 'caffeineoverdose', '2517']
]

To add, you can WRITE the object sorted, and you can have it displayed on screen sorted, but once it's defined as an object you lose the order. See stackoverflow.com/questions/5525795/… –  remus Jan 7 at 16:59

You could convert it into an array of objects:

[{ name: 'caffeineoverdose', number: '2517' }, {name: 'workhardplayhard', number: '761277'}, {name: 'familia', number: '4633452'}]

and then sort by id

array.sort(function(a,b){
    return a.number - b.number;
    }
);
