How to play audio?

Question

I am making a game with HTML5 and JavaScript.

How could I play game audio via JavaScript?

Answer 1

Easy with Jquery

// set audio tags with no preload

// add jquery to load

$(".my_audio").trigger('load');

// write methods for playing and stopping

function play_audio(task) {
      if(task == 'play'){
           $(".my_audio").trigger('play');
      }
      if(task == 'stop'){
           $(".my_audio").trigger('pause');
           $(".my_audio").prop("currentTime",0);
      }
 }

// decide how to control audio

PLAY
STOP

EDIT

To address @stomy's question, here is how you would use this approach to play a playlist:

Set your songs in an object:

playlist = {
    'song_1' : 'audio/splat.mp3',
    'song_2' : 'audio/saw.mp3',
    'song_3' : 'audio/marbles.mp3',
    'song_4' : 'audio/seagulls.mp3',
    'song_5' : 'audio/plane.mp3'
}

Use the trigger and play functions as before:

$(".my_audio").trigger('load');

function play_audio(task) {
      if(task == 'play'){
           $(".my_audio").trigger('play');
      }
      if(task == 'stop'){
           $(".my_audio").trigger('pause');
           $(".my_audio").prop("currentTime",0);
      }
 }

Load the first song dynamically:

keys = Object.keys(playlist);
$('.my_audio').append("");

Reset the audio source to the next song in the playlist, when the current song ends:

count = 0; 
$('.my_audio').on('ended', function() { 
   count++;  
   $("#sound_src").attr("src", playlist[keys[count]])[0];
   $(".my_audio").trigger('load');
   play_audio('play');
});
