Sorting a Backbone Collection After initialization

Question

I am using Backbone.js to render a list of items e.g Books. After the list is rendered, there are options for user to sort them. So if user clicks on Sort By Title, or Sort

Answer 1

This way works well and enables sorting by all attributes dynamically and handles ascending or descending:

var PhotoCollection = Backbone.Collection.extend({
    model: Photo,
    sortByField: function(field, direction){
            sorted = _.sortBy(this.models, function(model){
                return model.get(field);
            });

            if(direction === 'descending'){
                sorted = sorted.reverse()
            }

            this.models = sorted;
    }
});
