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

Change to comparator function by assigning a new function to it and call sort.

// Following example above do in the view:

// Assign new comparator
this.collection.comparator = function( model ) {
  return model.get( 'lastname' );
}

// Resort collection
this.collection.sort();

// Sort differently
this.collection.comparator = function( model ) {
  return model.get( 'age' );
}
this.collection.sort();
