Navigation With Jquery Smooth Scroll Causes Weird Behavior

Post a Comment
I have a navigation on my website that is powered by jQuery to smooth-scroll to the target ID, but it is acting very strange (Chrome, Firefox): Sometimes it doesn't actually move

Solution 1:

Here's a working version. Apparently this is due to the overflow-x:hidden from body's CSS rule. See this question.

Removed that rule, now it seems perfectly fine (or prefer the codepen below that, since SO's fullpage version is bugging out a bit):

$("#scrollOne").click(function() {
  $('html,body').animate({
    scrollTop: $("#one").offset().top
  }, 750);
});

$("#scrollTwo").click(function(e) {
  $('html,body').animate({
    scrollTop: $("#two").offset().top
  }, 750);
});

$("#scrollThree").click(function() {
  $('html,body').animate({
    scrollTop: $("#three").offset().top
  }, 750);
});

$("#scrollFour").click(function() {
  $('html,body').animate({
    scrollTop: $("#four").offset().top
  }, 750);
});
@import url("https://fonts.googleapis.com/css?family=Muli:400,600,700");
@keyframes nav-item {
  from {
    transform: translateY(-100px) translateX(-20px); }
  to {
    transform: translateY(0) translateX(0); } }

@keyframes nav-item-alt {
  from {
    opacity: 0; }
  to {
    opacity: 1; } }

Codepen version

Unrelated: I would also suggest adding .stop() before each .animate() call so every new animation stops the previous one.

Solution 2:

offset().top values change when page scrolled. so, you need to save those values at the beginning, also you should re-assign those values when window size changes. 

var oneTop = $("#one").offset().top;
    var twoTop = $("#two").offset().top;
    var threeTop = $("#three").offset().top;
    var fourTop = $("#four").offset().top;

Solution 3:

The problem is that you have height:100% on the body, so the offset returns wrong values (correct, but not what you expect).

Give height:auto and min-height:100% to body and it will work correctly.
