In my simple project I have 2 views - a line item view (Brand) and App. I have attached function that allows selecting multiple items:
var BrandView = Backbone.View.extend({
...some code...
toggle_select: function() {
this.model.selected = !this.model.selected;
if(this.model.selected) $(this.el).addClass('selected');
else $(this.el).removeClass('selected');
return this;
}
});
var AppView = Backbone.View.extend({
...some code...
delete_selected: function() {
_.each(Brands.selected(), function(model){
model.delete_selected();
});
return false;
},
});
Thing is, I want to know how many items are selected. In this setup selecting is NOT affecting the model and thus not firing any events. And from MVC concept I understand that views should not be directly talking to other views. So how can AppView know that something is being selected in BrandViews?
And more specifically, I AppView to know how many items were selected, so if more than 1 is selected, I show a menu for multiple selection.
