On screen in normal mode use at the click of a button the targeting of the screen to a div at the top:
$('html,body').animate({scrollTop:$('.backTop').offset().top}, 150);
But, having the screen in full screen how to make this function work?
Resolved,
Simply by using:
$('html,body').animate({scrollTop:$('.backTop').offset().top}, 150);
I was assigning to the scroll of the body, but should be assigning to the scroll of the div that is in fullscreen, getting:
$('#leitor').animate({
scrollTop: $(".backTop").offset().top
}, 150);
To solve your problem simply replace the code:
$('html,body').animate({scrollTop:$('.backTop').offset().top}, 150);
For this $('#leitor').animate({scrollTop:$('.leitor_top').offset().top}, 150);
For those who are in full screen is the div called "reader". I hope I have helped!
Try this:
var suaDiv = document.getElementById("leitor");
suaDiv.scrollTop = 0;
