backbone.jsHow can I set a model in Backbone.js?
Setting a model in Backbone.js is a simple process. To begin, you must first create a model object. This is done by extending the Backbone.Model class. For example:
var MyModel = Backbone.Model.extend({
defaults: {
name: '',
age: 0
}
});
Once you have a model object, you can create an instance of the model by using the new
keyword. The following example creates a new instance of the MyModel object:
var myModel = new MyModel();
You can then set attributes on the model instance using the set
method. This takes an object containing the attributes and their values. The following example sets the name
and age
attributes on the myModel
instance:
myModel.set({
name: 'John Doe',
age: 20
});
Finally, you can retrieve the attributes from the model instance using the get
method. This takes the name of the attribute you want to retrieve. The following example retrieves the name
attribute from the myModel
instance:
var name = myModel.get('name');
// Output: 'John Doe'
The set
and get
methods are the primary way to interact with a Backbone.js model.
