按键发出声音？

Question

Hi I am new javascript and in need of some code. I would like some code that when the user presses the key "c" a sound file called sound1.mp3 plays and then the user presses the key "y" another sound file called sound2.mp3 plays.

Thanks

Thomas

Well, I can't really say you provided a lot of information, but with what you wrote this is the best I could come up with.

I am assuming you don't have a lot of experience with js, so I will do my best to explain what I have done here.

First I am registering an event handler on the document object, which means that it will call a function with the event ( e ). The anonymous function will then assign the top-level variable audio to a new Audio object with whatever file you want, and after that it will play it.

Feel free to ask any questions you might have.

var audio;

document.onkeypress = function (e) {
  switch(e.key) {
    case "c":
      audio = new Audio("sound1.mp3");
      break;
    case "y":
      audio = new Audio("sound2.mp3");
      break;
  }

  audio.play();
};
