为什么点击时没有播放音频？

Question

I am creating a drum machine app. I can't find a method to play audio on pressing a button so I tried it my self. I created a separate method that returns audio element with source of audio file. I call that method on clicking a button but I can't hear any audio. Here is the code:

 class App extends Component {
  constructor(props){
      super(props);
            this.clicker=this.clicker.bind(this);

 }
  clicker(){
  return(
    <audio autoplay>
    <source src="./1.mp3" type="audio/mpeg"/>
    </audio>
   )
 }

render() {
 return (
  <div className="App">
    <input type="button" onClick={this.clicker} value="play">
    </input>
  </div>
  );
  }
 }

is my approach correct to creating a drum machine or is there any better way? any further help will be appreciated.. Thanks..

Answer 1

You need to add your audio player to the DOM then call play on it, here is a quick example.

 class App extends Component { constructor(props){ super(props); this.clicker=this.clicker.bind(this); } } render() { return ( <div className="App"> <input type="button" onClick="document.getElementById('myAudioPlayer').play()" value="play"> </input> </div> <audio autoplay id="myAudioPlayer"> <source src="./1.mp3" type="audio/mpeg"/> </audio> ); } }

Well after a little research and reading this HTML5 audio is not playing in my React app in localhost I get to know that you have to import mp3 files before using them as import mp3_file from {{filename}} . Then you can use them and it works.... Perfect!!
