javascript - Muting audio source from within an html iframe possibly using JS -


i working on gallery page quite few external html pages embedded using iframe, however, of these external pages have audio embedded them mute.

here sample code html files

gallery.html

<div id="pages">     <iframe id="embed" src="https://xyz.com/page1.html"></iframe>     <iframe id="embed" src="https://sdf.com/page2.html"></iframe> </div>

page1.html

<html>   <head>      <!-- head stuff-->   </head>   <body>      <audio autoplay>        <source src="http://audio.url/somefile.ogg" type="audio/ogg">        <source src="http://audio.url/somefile.mp3" type="audio/mpeg">        browser not support audio tag.      </audio>      <!--some more body content>   <body>  </html>

also, since i'm dealing multiple external pages, audio tags might not have ids attached them. makes document.getelementbyid() non-reliable option. i've experimented document.getelementsbytagname("input") couldn't quite audio muted. can please me this?

since these pages being served different domains not able access html within iframe due same origin policy.
