Let’s give an example tutorial on the use of html5 audio tags

html5 audio tags automatically play and pause

This is a mobile WeChat H5 activity page. One of the requirements is that the background music will automatically start playing after opening the page. Click the music icon button to control its playback and pause.

On the mobile side, for music playback, automatic playback and pause, the audio tag is necessary, so just start writing:

<code class="language-html"><i class="icon-music-outer">  
    <i class="forbid icon-music"></i>  
     <audio loop autoplay="autoplay" controls id="bgMusic" src="./music/musicMin.mp3">  
     </audio>  
</i>  
<script>  
    var $music = $(&#39;.icon-music-outer&#39;);  
    var $forbid = $music.find(&#39;.forbid&#39;);  
    var audio = document.getElementById(&#39;bgMusic&#39;);  
      $music.on(&#39;click&#39;, function () {  
        if ($forbid.hasClass(&#39;icon-music&#39;)) {  
            $forbid.removeClass(&#39;icon-music&#39;).addClass(&#39;icon-forbidMusic&#39;);  
        } else {  
            $forbid.removeClass(&#39;icon-forbidMusic&#39;).addClass(&#39;icon-music&#39;);  
        }  
  
        if (audio.paused) {  
            audio.play();  
            return  
        }  
        audio.pause();

How to use html5 audio tag? HTML5 autoplay implementation code example

## Simulate on Chrome browser, click on the small speaker, you can synchronously control the audio tag to play and pause, and it can also play automatically.

So I put it on my mobile phone and tested it, and the results came out. . . . .

Everything is normal on the Android phone;

But on the Apple phone, it cannot play automatically when you first enter the page

After checking a lot of information, I found out that this This is because Apple prohibits the automatic playback of audio unless the user actively triggers it in order to prevent the user from being in a traffic environment, which will lead to the theft of traffic. Of course, there are still ways to meet the demand. After all, it is run under someone else's WeChat browser. People have to lower their heads when they are under the eaves!

Another js file introduced by WeChat developers. The overall writing method is as follows: jq and native writing method
