Reverse sort order with Backbone.js

Question

With Backbone.js I\'ve got a collection set up with a comparator function. It\'s nicely sorting the models, but I\'d like to reverse the order.

How can I sort the m

Answer 1

The following worked well for me:

comparator: function(a, b) {
  // Optional call if you want case insensitive
  name1 = a.get('name').toLowerCase();
  name2 = b.get('name').toLowerCase();

  if name1 < name2
    ret = -1;
  else if name1 > name2
    ret = 1;
  else
    ret = 0;

  if this.sort_dir === "desc"
    ret = -ret
  return ret;
}

collection.sort_dir = "asc";
collection.sort(); // returns collection in ascending order
collection.sort_dir = "desc";
collection.sort(); // returns collection in descending order
