我如何根据按下的键使用 OnKeypress 来使用我的按钮

Question

你好，我想根据按下的键重现声音，但我如何传递到我的 onkeypress 中？我用 howler 重现声音，我使用映射功能为所有按钮重现和创建一个按钮，但我不知道如何将它与 onkeypress 一起使用，就像我希望它在我按下另一个键时改变按钮声音一样w等

//create an array for audioClips
const audioClips = [
{sound : bass, label: "BassDrum"},
{sound : hithat, label: "HitHat"},
{sound : ride, label: "Ride"},
{sound : snare, label: "Snare"},
{sound : splash, label: "Splash"},
{sound : tom, label: "Tom"},
]
class App extends Component {
SoundPlay = (src) => {
const sound = new Howl({
  src
});
sound.play();
}

RenderButtonAndSound = () => {
  return audioClips.map((soundObj,index) => {
    return(
      <button key={index}onKeyPress={() => this.SoundPlay(soundObj.sound)} onClick={() => 
 this.SoundPlay(soundObj.sound) }>
        {soundObj.label}
      </button>
    )
  });
  
 }

 render(){
Howler.volume(1.0)
return (
  <div className="App">
    <h2>
      My Virtual Drums
    </h2>
    {this.RenderButtonAndSound()}
  </div>
 );
 }
}

export default App;

使用 onKeyPress 事件，您可以检查正在输入的键。

   const keyboardEvents = (event) =>{
       console.log(event.key); // this will return string of key name like 'Enter'
       console.log(event.keyCode) //using keycode

  if (e.keyCode == 13) { //Press Enter
    this.SoundPlay(soundObj.sound)
  }

       //You can use If-Else or Switch statements to call different sound base on event.key
   }


RenderButtonAndSound = () => {
  return audioClips.map((soundObj,index) => {
    return(
      <button key={index} onKeyPress={(e) => this.keyboardEvents(e)} onClick={() => 
 this.SoundPlay(soundObj.sound) }>
        {soundObj.label}
      </button>
    )
  });
  
 }
