![]() If the input is invalid, it returns a specified error message or if the input is valid, it doesn’t specify anything and simply displays the result. Saves the data of the model by delegating to sync() method which reads and saves the model every time when a Backbone calls it.ĭestroys or removes the model from the server by using the Backbone.sync method which delegates the HTTP “delete” request. ![]() Merges the model’s state with attributes fetched from the server by delegating to Backbone.sync. Uses Backbone.sync to persist the state of a model to the server. Returns a copy of the attributes as an object for JSON stringification. The defaults hash (or function) can be used to specify the default attributes for your model. If you set the id in the attributes hash, it will be copied onto the model as a direct property.ĭefines a model’s unique identifier which contains the name of the member of the class which will be used as id.Ī special property of models, the cid or client id is a unique identifier automatically assigned to all models when they’re first created.Ĭhanges all the attributes that have changed after setting the attributes using the set() method. ![]() Removes all attributes from the model, including the idĪ special property of models, the id is an arbitrary string (integer id or UUID). Remove an attribute by deleting it from the internal attributes hash. If the attribute is set to a non-null or non-undefined value. It is like the get function, but returns the HTML-escaped version of a model’s attribute. Set a hash of attributes (one or many) on the model. Get the current value of an attribute from the model. When a model instance is created, the class’s constructor gets called and it is invoked by defining the initialize function when the model is created. If you define a preinitialize method, it will be invoked when the Model is first created, before any instantiation logic is run for the Model. To create a Model class of your own, you extend Backbone.Model and provide instance properties, as well as optional classProperties to be attached directly to the constructor function.įor use with models as ES classes.
