点击按钮时图片随机化成功，但声音无法播放。我不知道音频JS有什么问题，但它一直让我感到困惑。我想在点击同一个按钮的时候，让两者随机执行。我使用Chrome浏览器来测试我的工作。
<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>你要创建一个声音的数组，像这样。
var sounds = ["sound1.mp3", "sound2.mp3", "sound3.mp3", "sound4.mp3"].map(
(sound) => new Audio(sound)
);
你还有一个错别字，在开头的那一行 document.getElementById("Button").innerHTML, soundFile 有资本 F. 虽然我觉得你不需要那条线，但你可以通过呼叫来播放声音 play() 上，像 soundFile.play()请检查下面的片段。
//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" />';
