Sort numeric keys in object

Question

I have an object with keys and values are integer:

{
  10: 3,
  20: 3,
  30: 3,
  60: 1
}

I want to sort this object as

{
  60: 1,
  30: 3,
  20: 3,
  10: 3
}

Are you have any solutions to solve my problems?

Sorry for my bad English!

Answer 1

4.3.3 Object An object is a member of the type Object. It is an unordered collection of properties each of which contains a primitive value, object, or function. A function stored in a property of an object is called a method.

see Standard ECMA-262

Answer 2

I´ve prepared a little solution for you. Converting it first to an array, and then sorting by the property you need.

Also showing in the print the difference between objects {} and arrays [] . Check the fiddle, there you have a sorted array with the values from you object.

 var obj = { 10: 3, 20: 3, 30: 3, 60: 1 }; var keys = Object.keys(obj); var arr = []; for (i = 0; i < keys.length; i++) { arr.push({ val: obj[keys[i]], key: keys[i] }); } var ordered = false; while (!ordered) { var i = 0; ordered = true; for (i = 0; i < arr.length - 1; i++) { if (arr[i].val > arr[i + 1].val) { var pass = arr[i + 1].val; var passkey = arr[i + 1].key; arr[i + 1].val = arr[i].val; arr[i + 1].key = arr[i].key; arr[i].val = pass; arr[i].key = passkey; ordered = false; } } } var newObj = {}; for (i = 0; i < arr.length; i++) { newObj[arr[i].key] = arr[i].val console.log("val:" + arr[i].val + ",key:" + arr[i].key); } document.write("<p>THE ARRAY:" + JSON.stringify(arr) + "</p>"); document.write("<p>THE OBJECT:" + JSON.stringify(newObj) + "</p>");
