How to delete multiple models in backbone?

Question

JavaScript

Hello. Please tell me how can I remove several models from the collection. I do like this

addElement: function(el){
            if(this.collection.get(el.get('id')))
                this.collection.remove(el.get('id'));
            else
                this.collection.add(el);
            console.log(this.collection);
        }
....
....
....

_.each(this.collection.models, function(model){
                    model.destroy();
                });

but firstly, the models are partially deleted, secondly, the browser sends a delete request. But I need to remove some checked models from the collection. How to solve it?

What does "partly" mean? If you don't want the browser to send a delete request, then don't call the `destroy` method on the model. It is just what is needed so that the model is deleted from the database, that is, it is completely destroyed.
