backbone.jsHow do I initialize a Backbone.js Model?
A Backbone Model is a basic unit of data that your application will be using. To initialize a Backbone Model, you need to create a new instance of the Model class, passing in an object literal with the desired properties.
var myModel = new Backbone.Model({
property1: 'value1',
property2: 'value2'
});
This creates a new Model instance with two properties, property1
and property2
, with the respective values of value1
and value2
.
You can also pass in an array of attributes to the constructor, which will be set as properties on the Model:
var myModel = new Backbone.Model([
{property1: 'value1'},
{property2: 'value2'}
]);
The Model constructor also takes an optional options
parameter, which can be used to define any additional options for the model:
var myModel = new Backbone.Model({
property1: 'value1',
property2: 'value2'
}, {
option1: 'optionValue1',
option2: 'optionValue2'
});
Once the Model is initialized, you can access the properties and options using the get()
method:
var property1 = myModel.get('property1'); // returns 'value1'
var option1 = myModel.get('option1'); // returns 'optionValue1'
You can also set values on the model using the set()
method:
myModel.set('property1', 'newValue1');
