Call Backbone.Model#destroy() to remove and destroy a model from a collection. Backbone has no batch removal facility so you will have to remove them one by one.

it is as simple as collection.add or collection.remove

Refer for removing same is applicable for add.this

to get a collection of selected models from backgrid

var selectedModels = grid.getSelectedModels();

to remove

backgriCollections.remove(selectedModels);

Very simple.

Just removing them won't destroy them on the server. You have to call destroy on every single one of the models to delete them on the server. – Y.H Wong Jun 25 '13 at 03:14
understood, You point is considered when it is removed from collection :) – Java Questions Jun 25 '13 at 10:03
