Javascript -播放声音和数组中的随机值
Javascript -播放声音和数组中的随机值
提问于 2018-10-13 01:26:41
我正在试着做一个随机问题的测验。我希望每个问题都伴随着一个声音剪辑，一旦问题显示，它就会自动播放。我也想有一个按钮，使用户可以重新播放的声音剪辑。我如何才能做到这一点呢？
我知道如何用audioClips.play();播放单独的音频剪辑。但是，如果播放来自数组的音频剪辑，与问题“同步”呢？
这就是我到目前为止所知道的：
var country = ["Italy", "Spain", "Portugal", "France", "Greece", "Ireland", "Germany"];
var audioClips = ["italy.mp3", "spain.mp3", "portugal.mp3", "france.mp3", "greece.mp3", "ireland.mp3", "germany.mp3"];
var capital = ["rome", "madrid", "lisbon", "paris", "athens", "dublin", "berlin"];
var random001 = Math.floor(Math.random() * country.length);
document.getElementById("country").textContent = country[random001];
function submit001() {
var b = input001.value.toLowerCase();
var text;
if (b === capital[random001]) {
goToNextQuestion();
text = "Correct!";
} else {
text = input001.value.bold() + " is not correct!";
}
document.getElementById("input001").value = "";
document.getElementById("answer001").innerHTML = text;
}
function goToNextQuestion() {
document.getElementById("answer001").innerHTML = "";
random001 = Math.floor(Math.random() * country.length);
document.getElementById("country").innerHTML = country[random001];
document.getElementById("input001").focus();
}<p id="message001">What is the capital of <text id="country"></text>?</p>
<input type="text" id="input001" autofocus onKeyDown="if(event.keyCode==13) submit001()">
<p id="answer001"></p>
<button onclick="playAudio()" type="button">Replay Audio</button>

function playAudio() {
// if you know how to play audio then follow these step
//1. get file name from audioClips array at index randome001 like
audioClip = audioClips[random001]
// do whatever you need to do before playing audio like loading audio file or whatever
//2. play audioClip.
