+<h3 id="基本用法">基本用法</h3>
+
+<p>你可以完全使用 JavaScript 的 {{domxref("HTMLAudioElement.Audio", "Audio()")}} 构造函数来创建一个 <code>HTMLAudioElement</code> ：</p>
+
+<pre class="brush: js notranslate">var audioElement = new Audio('car_horn.wav');
+</pre>
+
+<p>然后你可以在这个元素上调用 <code>play()</code> 方法</p>
+
+<pre class="brush: js notranslate">audioElement.play();</pre>
+
+<div class="note">
+<p>一个常见的需求是在页面加载后马上去播放音频，现代浏览器的默认自动播放策略会阻止这一行为，参见 <a href="https://hacks.mozilla.org/2019/02/firefox-66-to-block-automatically-playing-audible-video-and-audio/">firefox</a> 和 <a href="https://developers.google.com/web/updates/2017/09/autoplay-policy-changes">chrome</a> 寻找最佳实践和解决方案。</p>
+</div>
+
+<p>一些经常被使用的属性，包括 {{domxref("HTMLMediaElement.src", "src")}}、{{domxref("HTMLMediaElement.currentTime", "currentTime")}}、{{domxref("HTMLMediaElement.duration", "duration")}}、{{domxref("HTMLMediaElement.paused", "paused")}}、{{domxref("HTMLMediaElement.muted", "muted")}} 和 {{domxref("HTMLMediaElement.volume", "volume")}}。以下这段代码赋值音频文件的播放时长给一个变量：</p>
+
+<pre class="brush: js notranslate">var audioElement = new Audio('car_horn.wav');
+audioElement.addEventListener('loadeddata', () =&gt; {
+  let duration = audioElement.duration;
+  // duration 变量现在存放音频的播放时长（单位秒）
+})</pre>
