Sort array of objects by arbitrary list in JavaScript

Question

Given an array of objects like this:

objects = [
  { id: \'aaaa\', description: \'foo\' },
  { id: \'bbbb\', description: \'bar\' },
  { id: \'cccc\', descri         


        

Answer 1

Try this:

objects.sort(function(a, b){
    return order.indexOf(a.id) - order.indexOf(b.id)
});

Assuming the variables are like you declared them in the question, this should return:

[
    { id: 'bbbb', description: 'bar' },
    { id: 'aaaa', description: 'foo' },
    { id: 'cccc', description: 'baz' }
];

(It actually modifies the objects variable)
