如何在使用 1 类/1 ID 的同时使用 JavaScript 播放多个音频声音而不必使用多个函数来播放它们

Question

I have multiple audio files (5). I'm attaching the files to an image so that when they are clicked, they play a specific audio. However, I have to use 5 different IDs & functions to make them play a unique sound.

HTML:

<img src="image1" alt="" class="box rounded shadow-lg cursor-pointer" id="" value="PLAY" onclick="ricekrispy()">
        
<audio id="ricekrispy" src="sound.mp3"></audio>

<img src="image2" alt="" class="box rounded shadow-lg cursor-pointer" id="" value="PLAY" onclick="skittles()">
        
<audio id="skittles" src="sound.mp3"></audio>

<img src="image3" alt="" class="box rounded shadow-lg cursor-pointer" id="" value="PLAY" onclick="Mandms()">
        
<audio id="Mandms" src="audio3.mp3"></audio>

<img src="image4" alt="" class="box rounded shadow-lg cursor-pointer" id="" value="PLAY" onclick="nuggets()">
        
<audio id="nuggets" src="audio4.mp3"></audio>

<img src="image5" alt="" class="box rounded shadow-lg cursor-pointer" id="" value="PLAY" onclick="fries()">
        
<audio id="fries" src="audio5.mp3"></audio>

JavaScript:

function ricekrispy() {
    let audio = document.getElementById('ricekrispy');
    audio.play();
  }

  function skittles() {
    let audio = document.getElementById('skittles');
    audio.play();
  }

  function mandms() {
    let audio = document.getElementById('mandms');
    audio.play();
  }

  function nuggets() {
    let audio = document.getElementById('nuggets');
    audio.play();
  }

  function fries() {
    let audio = document.getElementById('fries');
    audio.play();
  }

I reused the functions and changed the name 1 by 1. I'm looking for a way to use a forEach to grab the element/ID/class without having to put script onto the element

(value="play" & onclick="function()")

Answer 1

The OP might consider a more modern and generic DOM scripting approach which frees the OP from most id attributes and from inline-scripting.

The next following implementation uses...

• the Selectors API which enables the OP of accessing any single element-node or node-list customized / according to the OP's needs,

• Event Listeners ,

• Events ,

• Handler Functions .

One would query a node-list of image elements which all feature a custom data-audio-source attribute.

document.querySelectorAll('img[data-audio-source]');

Such data-* global attributes are good for carrying additional information which relates to the very element that is featuring it. Here one would assign the audio-source that is related to its image.

<img src="/path/to/image" data-audio-source="/path/to/audio" />

One then needs to subscribe forEach node-list's image-element an event-listener with a callback-function which handles eg the image-element's 'click' -event .

The handler-function which gets passed as callback to addEventListener expects an event -object as its sole parameter. The event's currentTarget does refer to the clicked image-element (the very target of the event subscription). Since such an element features a custom data-audio-source attribute one can read the attribute-value via the element's related dataset -property...

const source = elmImg.dataset.audioSource;

Within the handler one would query the correct audio-player element, pause it, assign the correct media-source/reference to it and start play ing it (again).

 function handleAutoPlay(evt) { const elmImg = evt.currentTarget; const source = elmImg.dataset.audioSource; const elmPlayer = document.querySelector('#auto-player'); elmPlayer.pause(); elmPlayer.src = source; elmPlayer.play(); } document.querySelectorAll('img[data-audio-source]').forEach(elmImg => elmImg.addEventListener('click', handleAutoPlay) );

 body { margin: 0; } p { margin: 0 0 5px 0; } img[data-audio-source] { height: 70px; cursor: pointer; }
