Question

Can i create multiples functions inside for loop?

var mySound1 = new buzz.sound( "laser-01", { formats: [ "ogg", "mp3", "acc" ]});
var mySound2 = new buzz.sound( "alien-noise-01", {formats: [ "ogg", "mp3", "acc" ]});

var sound = [mySound1, mySound2]

// additional sounds
var $i;
for ( $i = 0; $i< sound.length; $i++){
    function playsound[$i](){   
           a[$i].play().fadeIn().loop();
        }
}

playsound1();

Answer 1

You’d be better off just passing $i as a parameter to the playsound function

var sounds = [
    new buzz.sound( "laser-01", { formats: [ "ogg", "mp3", "acc" ]}),
    new buzz.sound( "alien-noise-01", {formats: [ "ogg", "mp3", "acc" ]})
];

var playsound = function (i) {   
   sounds[i].play().fadeIn().loop();
}

playsound(1);

And if you really want the playsound1() style function name, you could eval it (though I suggest against adding this):

for (var i = 0; i < sounds.length; i++){
    eval('var playsound' + (i+1) + ' = function() { playsound(' + i + '); };');
}

playsound1();
playsound2();
