setTimeout or setInterval or requestAnimationFrame

Question

For HTML5 games,with canvas animation for mobile devices.

I\'m facing some performance issues which differ the speed between each device and the others.

Answer 1

window.requestAnimFrame = function(){
    return (
        window.requestAnimationFrame       || 
        window.webkitRequestAnimationFrame || 
        window.mozRequestAnimationFrame    || 
        window.oRequestAnimationFrame      || 
        window.msRequestAnimationFrame     || 
        function(/* function */ draw1){
            window.setTimeout(draw1, 1000 / 60);
        }
    );
}();
   window.requestAnimFrame(draw);
})();

use this function for all cases
