簡単な説明：
私はFullcalendarJSと統合されたバックボーンアプリに取り組んでいます。イベントを作成または編集するときに、カレンダーをクリックすると、情報を求めるモーダルがポップアップ表示されます。問題は、モーダルがポップアップしたときに、「this.model」を使用し.get()て現在のイベント.set()に関する情報または新しいイベントに関する情報を表示する必要があることです。エラーが発生し続けます：
Uncaught TypeError：undefinedのメソッド'get'を呼び出すことが
できませんUncaughtTypeError：undefinedのメソッド'set'を呼び出すことができません
私の質問： クリックされたビューの現在のモデルを設定するための適切な方法は何ですか？
関連するコードは次のとおりです。
モデルとコレクション：
var Event = Backbone.Model.extend({
methodToURL: {
'create': addDayURL,
'update': addDayURL,
//'delete': '/user/remove'
},
sync: function(method, model, options) {
options = options || {};
options.url = model.methodToURL[method.toLowerCase()];
Backbone.sync(method, model, options);
}
});
var Events = Backbone.Collection.extend({
model: Event,
url: allDaysURL
});
