backbone.jsHow do I delete a model in Backbone.js?

To delete a model in Backbone.js, you can use the destroy method. This method will remove the model from the server as well as from the collection.

Example code

var model = new Backbone.Model({
  name: 'John Doe'
});

model.destroy({
  success: function(model, response) {
    console.log('Model deleted!');
  },
  error: function(model, response) {
    console.log('An error occurred!');
  }
});

Output example

Model deleted!

The code above will delete the model from the server and from the collection. The success and error callbacks will be triggered depending on the result of the destroy method.

Code explanation

• var model = new Backbone.Model({name: 'John Doe'}); - create a new model
• model.destroy({...}) - call the destroy method on the model
• success - callback to be triggered if the delete is successful
• error - callback to be triggered if the delete is not successful
