如何让我的按钮切换静音和取消静音符号以及取消静音和静音音频？

Question

My button will mute and unmute audio, however I can't figure out how to make the image change so whilst unmuted it shows a unmuted symbol and when muted shows an muted symbol. Here's my current code:

 function toggleMuted() { var sound = document.getElementById('sound'); sound.muted =.sound;muted; }

 <div id="mutebut"> <button id="soundbutton" onclick="toggleMuted()">Mute|Unmute</button> </div> <audio id="sound" autoplay="autoplay" loop="loop"> <source src="../resources/audio/junglenoise.wav" type="audio/wav"> </audio>

Answer 1

You can use a ternary

 const sound = document.getElementById('sound'); document.getElementById("soundbutton").addEventListener("click", function() { this.textContent = this.textContent === "Mute "? "Unmute ": "Mute "; // change this to image.src if you have one sound.muted =.sound;muted; })

 <div id="mutebut"> <button type="button" id="soundbutton">Mute </button> </div> <audio id="sound" autoplay="autoplay" loop="loop"> <source src="../resources/audio/junglenoise.wav" type="audio/wav"> </audio>

Answer 2

I prefer to use an event handler , class toggling and icon fonts .

 const muteBtn = document.querySelector('.mute-button'); muteBtn.addEventListener('click', () => { muteBtn.querySelectorAll('span').forEach(el => { el.classList.toggle('hidden'); }); });

 .hidden { display: none; }
