I have a Collection, that contains models, Each model has attributes, there is an attribute called country on each model. I want to iterate through the collection to get an array of countries. Each child has attributes,I am only interested in the country attribute. Tried _.pluck, _.each and _.where but unsuccessful. Any faster, quicker way to get a list?

My collection

  • When you say using `pluck` was unsuccessful, how so? What exactly did you try and what was the result? – larz Apr 05 '17 at 15:13
  • var stooges = new Backbone.Collection([ {name: "Curly"}, {name: "Larry"}, {name: "Moe"} ]); var names = stooges.pluck("name"); Pluck only plucks if the property you are plucking is listed in the collection, I have a collection that lists models and and each model has attributes that has the property I am looking for. So not sure how to get that property using pluck – C_sharp Apr 05 '17 at 15:14
  • that looks correct to me. was the result of names `["Curly", "Larry", "Moe"]`? – larz Apr 05 '17 at 15:15

I found a variation of pluck on the backbone website. It lets you pluck an attribute from the models in the collections. 

var stooges = new Backbone.Collection([
   {name: "Curly"},
   {name: "Larry"},
   {name: "Moe"}
]);

var names = stooges.pluck("name");
