I found that the $(window).resize() will be triggered when you scroll up/down the website on a mobile device. To prevent this happens, we could add a checking on the screen width.

var width = $(window).width();
$(window).resize(function(){
  if ($(window).width() != width) {
    // Only action on screen width change
    width = $(window).width();
  }
});

Done =)
