Add a stop function to the html5 audio element

By | June 30, 2013

The Audio element of html5 does not yet have a stop function, but has a pause function. So here is a simple trick to add a stop function to your Audio elements by modifying the prototoype of the class.

//Give the Audio element a stop function
HTMLAudioElement.prototype.stop = function()
	this.currentTime = 0.0;

The function would first pause the audio element, then would set the seek position to 0.0 which is the beginning.
Can be used comfortably like this

var aud = new Audio();
aud.src = 'background.ogg';;

//stop it

The technique can be used to add more useful functions to the element as per the need.

Note :

You could try adding to Audio class directly like this

Audio.prototype.stop = function()
	this.currentTime = 0.0;

Using the above, aud.stop() would work in chrome and opera but not in Firefox (v. 17.0.1 at the time of writing this article).
