Question

Chrome汽车政策在2018年4月发生了变化。我愿利用其中的一项政策: 如果用户与领域(浮标、主线等)互动,则允许与声音自动交换。因此,我有一个网页。

<a href="d2.php">dictation</a>

当用户在上页上点击链接时,第二页(d2.php)被装上。其内容如下:

<!DOCTYPE html>
<html>
<body>

<h1>The audio autoplay attribute</h1>

<p>Click on the play button to play a sound:</p>

<audio controls autoplay>
  <source src="https://www.w3schools.com/tags/horse.ogg" type="audio/ogg">
  <source src="https://www.w3schools.com/tags/horse.mp3" type="audio/mpeg">
  Your browser does not support the audio element.
</audio>

</body>
</html>

The audio autoplay works on Chrome as expected. Also it can be verified that the autoplay works with Edge and Opera. However,

It does not work with Firefox 117.0.1 (64-bit), ie, audio is not autoplayed.
With a version of Safari I installed on my Ubuntu using WINE, it give me "Your browser does not support the audio element." message.

I would consider the Safari message is caused by my Ubuntu - WINE installation. However, could anybody help me with the firefox audio autoplay? I am open to any solution with HTML, PHP, and JaveScript. Thanks in advance.

PS:我阅读了许多因特网上的“html声自动”节目。

<编码> 在缺席的情况下,-(至少至最新版本)(截至今天:>117.0.1),自动演播音被封,因此,如果在同一页上出现人的互动,则必须启动(例如,点击子)。

So, apart from the built-in "play" button in the audio element, you may use JS (say associated with the click of a button) to trigger the audio play, you may (as a demonstration):

Assign the audio an ID (e.g. audio1)
Trigger play(), such as document.getElementById( audio1 ).play();

因此,该法典是:

<!DOCTYPE html>
<html>
<body>

<h1>The audio autoplay attribute</h1>

<p>Click on the play button to play a sound:</p>

<audio controls autoplay id=audio1>
  <source src="https://www.w3schools.com/tags/horse.ogg" type="audio/ogg">
  <source src="https://www.w3schools.com/tags/horse.mp3" type="audio/mpeg">
  Your browser does not support the audio element.
</audio>

<input type=button onclick="javascript:play1();" value="Play">
</body>
</html>

<script>
function play1(){
document.getElementById( audio1 ).play();
}
</script>

click settings in Firefox,
click privacy & security,
scroll to "Autoplay" and click "Settigs"
choose choose "Allow Audio and Video"

如果你做上述工作,那么如果该网页装上了火ox,就会允许自动播放录音。
