HTMLMediaElement.seekable

The seekable read-only property of the HTMLMediaElement returns a TimeRanges object that contains the time ranges that the user is able to seek to, if any.

SyntaxEdit

var seekable = audioOrVideo.seekable;

Value

A TimeRanges object.

ExamplesEdit

This example will listen for audio data to be loaded for the element `example`. It will then check if at least the current playback position has been loaded. If it has, the audio will play.

<audio id="example" preload="auto">
 <source src="sound.ogg" type="audio/ogg" />
</audio>

var obj = document.getElementById('example');

obj.addEventListener('loadeddata', function() {

  if(obj.readyState >= 2) {
    obj.play();
  }

});

SpecificationsEdit

Browser compatibilityEdit

[1] Available after switching the about:config preference media.mediasource.enabled to true. In addition, support was limited to a whitelist of sites, for example YouTube, Netflix, and other popular streaming sites. The whitelist was removed and Media Source Extensions was enabled by default in 42+ for all sites.
