reactjs - 灵活的 storeListeners 事件发射器

Question

有没有办法发现哪个处理程序触发了事件？

例如，我的商店：

handlers: {
        surahReceived(payload) {
            this._surah = payload.surah;
            this.emitChange();
        },
        ayahsReceived(payload) {
            this.dispatcher.waitFor('AyahStore', function() {
                this._surah.ayahs = this.dispatcher.getStore(AyahStore).getAyahs();
            }.bind(this));
            this.emitChange();
        },
        surahListReceived(payload) {
            this._surahs = payload.surahs;
            this.emitChange();
        }
    }

当最后一个函数触发时，我的听众：

statics: {
        storeListeners: {
            _onSurahReceived: [SurahStore]
        }
    },

我想知道哪个函数触发了事件

Answer 1

我找到了答案：

您可以将参数传递给emitChange.

例如：

surahListReceived(payload) {
            this._surahs = payload.surahs;
            this.emitChange(1);
        }

那么在你看来：

statics: {
        storeListeners: {
            _onSurahReceived: [SurahStore]
        }
    },
_onSurahReceived: function(e) {
  console.log(e) // Should be 1
}
