以下のような解決策も考えられます。
var OuterView = Backbone.View.extend({
initialize: function() {
this.inner = new InnerView();
},
render: function() {

this.$el.empty()
も可
this.$el.html(template);
this.$el.append(this.inner.$el);
this.inner.render();
}
});
var InnerView = Backbone.View.extend({
render: function
() {
this.$el.html(template);
this.delegateEvents();
}
});

QuotationMarkI wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.
