Proper way to sort a backbone.js collection on the fly

Question

I can successfully do this:

App.SomeCollection = Backbone.Collection.extend({
  comparator: function( collection ){
    return( collection.get( \'lastName\' ) );         


        

Answer 1

Looking at the source code, it seems there's a simple way to do it, setting comparator to string instead of function. This works, given Backbone.Collection mycollection:

        mycollection.comparator = key;
        mycollection.sort();
