[SOLVED] How to get elements from object where in Backbone?

How to get elements from object where in Backbone?

I have object-model as:

var wo = new WordModel({
    "url": window.location.href,
    "time": toDay(),
    "w": w.trim()
});

timelineCollection.add(wo);

I try to get all element in timelineCollection where time is 04/02/2017. I tried this:

var o = {
    time: "04/02/2017"
};

var filtered = timelineCollection.where(o);
console.log(filtered);

But it does not work for me

Solution

Backbone's collection where function is really what you should use for this.

// short syntax, every object becomes a Backbone.Model by default.
var collection = new Backbone.Collection([{
    id: 0,
    time: "04/02/2017",
  }, {
    id: 1,
    time: "05/02/2017",
  },
  // you can mix both plain objects and Model instances
  new Backbone.Model({
    id: 2,
    time: "04/07/2017",
  }), new Backbone.Model({
    id: 3,
    time: "04/02/2017",
  })
]);

// passing an existing model works too.
var model = new Backbone.Model({
  id: 4,
  time: "04/02/2017",
});

collection.add(model);

console.log(collection.where({
  time: "04/02/2017"
}));
