javascript - How to set volume of audio object?

Question

I know that i can create an audio object like this:

var audio = new Audio("test.wav");

And i know how i can play the audio:

audio.play();

I used the following for loop to output all functions from audio:

var myAudioObject = new Audio();

for (var key in myAudioObject)
{
   if (typeof myAudioObject[key] === "function")
   {
       console.log(key);
   }
}

Answer 1

It's not a function, it's a property called volume.

audio.volume = 0.2;

HTMLMediaElement volume ^MDN
