backbone.jsHow do I use a Backbone.js collection to manage data?
A Backbone.js collection is a JavaScript object that can be used to manage data. It provides an API for adding, removing, and fetching models from the collection. Here's an example of how to create a collection and add models to it:
var MyCollection = Backbone.Collection.extend({});
var myCollection = new MyCollection();
myCollection.add([
{name: "John", age: 30},
{name: "Jane", age: 25},
{name: "Sam", age: 28}
]);
This code will create a new collection called MyCollection
and add three models to it. The models will have two properties each - name
and age
.
You can then access the models in the collection using the get
method. For example, to get the model with the name "John":
var johnModel = myCollection.get("John");
console.log(johnModel.get("age")); // 30
You can also use the each
method to loop through all the models in the collection:
myCollection.each(function(model) {
console.log(model.get("name"));
});
// John
// Jane
// Sam
You can find more information about Backbone.js collections in the official documentation.
