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

So, this was my solution that actually worked.

  App.Collection = Backbone.Collection.extend({

    model:App.Model,

    initialize: function(){
      this.sortVar = 'firstName';
    },

    comparator: function( collection ){
      var that = this;
      return( collection.get( that.sortVar ) );
    }

  });

Then in the view, I have to M-I-C-K-E-Y M-O-U-S-E it like this:

this.collections.sortVar = 'lastVar'

this.collections.sort( this.comparator ).each( function(){
  // All the stuff I want to do with the sorted collection... 
});

Since Josh Earl was the only one to even attempt a solution and he did lead me in the right direction, I accept his answer. Thanks Josh :)
