javascript - How to add a mute button to my app? -


i have few events in app make sounds.

for example,

  • background music looped
  • background on click makes sound
  • when 2 rectangles collide makes sound

what want have button when clicked toggles between letting sounds play , not letting them play.

i don't want have load of if statements on each sound, there way around ?

here how im calling sounds @ moment 

//html     <div id='mainright'></div>  //js var mainright = $('#mainright');     $(mainright).width(windowdim.width/2).height(windowdim.height);     $(mainright).addclass('mainright');      var sounds = {          coinhit : new audio('./sound/coincollect.wav'),         playerclick : new audio('./sound/playerclick.wav'),         gameover : new audio('./sound/gameover.wav'),         backgroundmusic : new audio('./sound/backgroundmusic.wav')      }      sounds.backgroundmusic.addeventlistener('ended', function() {         this.currenttime = 0;         this.play();      }, false);     sounds.backgroundmusic.play();     sounds.backgroundmusic.volume = 0.01;      $('#mainright').click(function()     {         sounds.playerclick.load();         sounds.playerclick.play();     }

try this...

function toggleaudio() {     for(var key in sounds) {         sounds[key].muted = !sounds[key].muted;     } }

just fire every time hit mute button. toggle muted state of each audio object in sounds object.
