Reorder Array Of Objects

  var originalObject = [{
  "CatID": 15,
  "Currently": "is One",
  "ParentID": 16,
  "Should": "should be One"
  }, {
  "CatID": 17,
  "Currently": "is Two",
  "ParentID": 16,
  "Should": "should be Two"
  }, {
  "CatID": 18,
  "Currently": "is Three",
  "ParentID": 16,
  "Should": "should be Three"
  }, {
  "CatID": 22,
  "Currently": "is Four",
  "ParentID": 16,
  "Should": "should be Seven"
  }, {
  "CatID": 28,
  "Currently": "is Five",
  "ParentID": 16,
  "Should": "should be Eight"
  }, {
  "CatID": 92,
  "Currently": "is Six",
  "ParentID": 18,
  "Should": "should be Four"
  }, {
  "CatID": 30,
  "Currently": "is Seven",
  "ParentID": 92,
  "Should": "should be Five"
  }, {
  "CatID": 95,
  "Currently": "is Nine",
  "ParentID": 30,
  "Should": "should be Six"
  }];

  var localParentID = '';
  var localArr = [];

  for (var i in originalObject) {
  var iObj = originalObject[i];

  $('#displayDiv').append('Parent is ' + iObj['ParentID'] + ' ' + iObj['Currently'] + ' ' + iObj['CatID'] + ' ' + iObj['Should'] + '<br />');
  }

How can I sort the array above so that the ouput matches "should" order as opposed to "currently" order? It should be ordered by currently with should ParentID being attached to currently CatID.
Can't quite make this behave.

 

Well first, switch that "should be x" text to just that number. Then do a Array.sort with a callback, so the callback can get at the object's 'Should' property. (not that a property should start with an upper-case letter implying that it is in fact a CLASS)

var data = [
	{
		"CatID": 15,
		"Currently": "is One",
		"ParentID": 16,
		"Should": 1
	}, {
		"CatID": 17,
		"Currently": "is Two",
		"ParentID": 16,
		"Should": 4
	}, {
		"CatID": 18,
		"Currently": "is Three",
		"ParentID": 16,
		"Should": 3
	}, {
		"CatID": 22,
		"Currently": "is Four",
		"ParentID": 16,
		"Should": 7
	}, {
		"CatID": 28,
		"Currently": "is Five",
		"ParentID": 16,
		"Should": 8
	}, {
		"CatID": 92,
		"Currently": "is Six",
		"ParentID": 18,
		"Should": 2
	}, {
		"CatID": 30,
		"Currently": "is Seven",
		"ParentID": 92,
		"Should": 5
	}, {
		"CatID": 95,
		"Currently": "is Nine",
		"ParentID": 30,
		"Should": 6
	}
];

function shouldCompare(a, b) { return a.Should - b.Should; }

data.sort(shouldCompare);

Code (markup):

That's it. The array is in the 'should' order.
