    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.

    Syntax

    var seekable = audioOrVideo.seekable;

    Value

    A TimeRanges object.

    Examples

    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();
  }

});
