图像在按钮单击时成功随机化，但不会播放声音。我不知道音频 JS 有什么问题，但它一直困扰着我。我想让两者在单击同一个按钮时随机执行。我正在使用 Chrome 来测试我的工作。<script type = "text/javascript"> //Create random picture array function imgchange() { var myImages1 = new Array(); myImages1[1] = "Matthew1.jpg"; myImages1[2] = "Matthew2.jpg"; myImages1[3] = "Matthew3.jpg"; myImages1[4] = "Matthew4.jpg"; //Image Array myImages1[5] = "Matthew5.jpg"; myImages1[6] = "Matthew6.jpg"; myImages1[7] = "Matthew7.jpg"; var rnd = Math.floor(Math.random() * myImages1.length);// Random Choice of Image if (rnd == 0) { rnd = 1; } document.getElementById("gen-img").src = myImages1[rnd];//Gets Image } function playRandomSound() { //An array to house all of the URLs of your sounds var sounds = new Audio["sound1.mp3", "sound2.mp3", "sound3.mp3", "sound4.mp3"]; //This line will select a random sound to play out of your provided URLS var soundFile = sounds[Math.floor(Math.random() * sounds.length)]; //Find the player element that you created and generate an embed file to play the sound within it document.getElementById("Button").innerHTML = "<embed src=\"" + soundfile + "\" hidden=\"true\" autostart=\"true\" loop=\"false\" />"; </script><body style="height: 663px"> <div class="Title" id="title">Alright! Alright! Alright!</div> <p><img id="gen-img" src="img/who/1.jpg"></p> <p> <input id="Button" type="button" value="Random" onclick="imgchange(); playRandomSound();"/></p> </body>

您必须像这样创建一组声音：
var sounds = ["sound1.mp3", "sound2.mp3", "sound3.mp3", "sound4.mp3"].map(
(sound) => new Audio(sound)
);
您在开头的行中也有一个错字document.getElementById("Button").innerHTML，soundFile有一个大写字母F。虽然我认为您不需要那条线，但您可以通过调用play()它来播放声音，例如soundFile.play()，请查看下面的代码段：
//Create random picture array
function imgchange() {
var myImages1 = new Array();
myImages1[1] = "Matthew1.jpg";
myImages1[2] = "Matthew2.jpg";
myImages1[3] = "Matthew3.jpg";
myImages1[4] = "Matthew4.jpg"; //Image Array
myImages1[5] = "Matthew5.jpg";
myImages1[6] = "Matthew6.jpg";
myImages1[7] = "Matthew7.jpg";
var rnd = Math.floor(Math.random() * myImages1.length); // Random Choice of Image
if (rnd == 0) {
rnd = 1;
}
document.getElementById("gen-img").src = myImages1[rnd]; //Gets Image
}
function playRandomSound() {
//An array to house all of the URLs of your sounds
var sounds = [
new Audio(
"https://interactive-examples.mdn.mozilla.net/media/examples/t-rex-roar.mp3"
),
];
// var sounds = new Audio([
// ("sound1.mp3", "sound2.mp3", "sound3.mp3", "sound4.mp3")
// ]();
//This line will select a random sound to play out of your provided URLS
var soundFile = sounds[Math.floor(Math.random() * sounds.length)];
soundFile.play()
//Find the player element that you created and generate an embed file to play the sound within it
document.getElementById("Button").innerHTML =
'<embed src="' +
soundFile +
'" hidden="true" autostart="true" loop="false" />';
}
<div class="Title" id="title">Alright! Alright! Alright!</div>
<p><img id="gen-img" src="img/who/1.jpg" /></p>
<p>
<input id="Button" type="button" value="Random" onclick="imgchange(); playRandomSound();" />
</p>
