Question

My json object looks like this:

events:{
"2": {
    "action": "some value",
    "property": "some value"
}
"0": {
    "action": "some value",
    "property": "some value"
}
"1": {
    "action": "some value",
    "property": "some value"
}

}

I need to sort the properties of the object. Is there anyway to do this? The result should be like this:

events:{
"0": {
    "action": "some value",
    "property": "some value"
}
"1": {
    "action": "some value",
    "property": "some value"
}
"2": {
    "action": "some value",
    "property": "some value"
}

}

To guarantee order, like @Joseph said, it needs to be in an array:

var events = {
  "2": {
    "action": "some value",
    "property": "some value"
  },
  "0": {
    "action": "some value",
    "property": "some value"
  },
  "1": {
    "action": "some value",
    "property": "some value"
  }
};

var eventOrder = [];

for( var prop in events ){
  if( events.hasOwnProperty( prop ) ){
    eventOrder.push( prop );
  }
}

eventOrder.sort();

Note: this is going to sort by ALPHABETICAL order since you’re using strings, so if you have more than 9 items, you may end up with eventOrder as [ “1”, “10”, “2”, … ]. If this is not desired, you could parseInt before storing in the array, and the force to string later when you’re doing lookups.
