Like i explain here , i can\'t use window.setTimeout() anymore and any window classical functions like clearInterval etc ...); but i need calling a JS block code as an async one
Try using jQuery version 3.0 .animate(), which now uses requestAnimationFrame
// Creates a jQ object where elem set to index of [0]
// a plain object with value of 0 `{to:0}`
// call .animate() chained to the jQ object
// Animates `{to:0}` value from 0 - 1
// $({to:0}).animate({to:1}
var duration = 5000;
$({to:0}).animate({to:1}, duration, function() {
// do stuff after `duration` elapsed
$("#messageTimer").html("Happy New Year ! (working version)")
})
