解決策
ビューが別のビューを含んでいる状況（例えば、フォトギャラリーのビューが拡大写真のビュー
を含む、など）で、子ビューから親ビューに対して描画あるいは再描画を行いたいことがあるでしょ
う。これはとても簡単に実現できます。
最も簡単な解決策は、
this.parentView.render();
のようにすることです。
しかし、ここでは制御の反転が望まれます。イベントを利用するのがよいでしょう。
特定のイベントが発生したときに描画を行いたいとします。イベント名は
somethingHappened
とします。親ビューは子ビューを監視し、イベントの発生を待ち受けます。イベントが発生すると
自身の描画を行います。
親ビューでは次のようにコードを記述します。
//
親ビューでの監視
this.listenTo(this.childView, 'somethingHappened', this.render);
//
親ビューでの監視解除
this.stopListening(this.childView, 'somethingHappened');
子ビューでの処理は以下のようになります。
//
イベントの発生
this.trigger('somethingHappened');
子ビューが
somethingHappened
イベントを発生させると、親ビューの
render
関数が呼び出さ
れます。
