是否可以在减速机本身发送动作？我有一个进度条和一个音频元素.目标是在音频元素中更新时间时更新进度条.但是我不知道将ontimeupdate事件处理程序放在何处,或者如何在ontimeupdate的回调中调度一个动作来更新进度条.这是我的代码:

//reducer

const initialState = {
    audioElement: new AudioElement('test.mp3'),
    progress: 0.0
}

initialState.audioElement.audio.ontimeupdate = () => {
    console.log('progress', initialState.audioElement.currentTime/initialState.audioElement.duration);
    //how to dispatch 'SET_PROGRESS_VALUE' now?
};


const audio = (state=initialState, action) => {
    switch(action.type){
        case 'SET_PROGRESS_VALUE':
            return Object.assign({}, state, {progress: action.progress});
        default: return state;
    }

}

export default audio;
