Sorting JSON by values

Question

I have a very simple JSON object like the following:

{
   \"people\":[
      {
         \"f_name\":\"john\",
         \"l_name\":\"doe\",
         \"sequence

Here's a multiple-level sort method. I'm including a snippet from an Angular JS module, but you can accomplish the same thing by scoping the sort keys objects such that your sort function has access to them. You can see the full module at Plunker.

$scope.sortMyData = function (a, b)
{
  var retVal = 0, key;
  for (var i = 0; i < $scope.sortKeys.length; i++)
  {
    if (retVal !== 0)
    {
      break;
    }
    else
    {
      key = $scope.sortKeys[i];
      if ('asc' === key.direction)
      {
        retVal = (a[key.field] < b[key.field]) ? -1 : (a[key.field] > b[key.field]) ? 1 : 0;
      }
      else
      {
        retVal = (a[key.field] < b[key.field]) ? 1 : (a[key.field] > b[key.field]) ? -1 : 0;
      }
    }
  }
  return retVal;
};
