Question

I have the code of go to top sroll function. The button that am fixed in my home page is showing when am redirecting home page i dont want that button in top of my home page i want that button while scrolling down wot i do?

Answer 1

i think i didn't get your question right but maybe you need to try "position: fixed" for the tag?! is that what you are looking for?

edit:

set your top-button to invisible:

#top {
  visibility: hidden;
}

when the user scrolls you activate it!

$(window).scroll(function () { 
  $('#top').css("visibility", "visible"); 
});

when the top-button is clicked you simply hide it again:

$('#top').click(function () { 
  $('#top').css("visibility", "hidden"); 
});
