Disable elastic scrolling in Safari [duplicate]

Answer 1

You could check if the scroll-offsets are in the bounds. If they go beyond, set them back.

var scrollX = 0;
var scrollY = 0;
var scrollMinX = 0;
var scrollMinY = 0;
var scrollMaxX = document.body.scrollWidth - window.innerWidth;
var scrollMaxY = document.body.scrollHeight - window.innerHeight;

// make sure that we work with the correct dimensions
window.addEventListener('resize', function () {
  scrollMaxX = document.body.scrollWidth - window.innerWidth;
  scrollMaxY = document.body.scrollHeight - window.innerHeight;
}, false);

// where the magic happens
window.addEventListener('scroll', function () {
  scrollX = window.scrollX;
  scrollY = window.scrollY;

  if (scrollX <= scrollMinX) scrollTo(scrollMinX, window.scrollY);
  if (scrollX >= scrollMaxX) scrollTo(scrollMaxX, window.scrollY);

  if (scrollY <= scrollMinY) scrollTo(window.scrollX, scrollMinY);
  if (scrollY >= scrollMaxY) scrollTo(window.scrollX, scrollMaxY);
}, false);

Answer 2

None of the above solutions worked for me, however instead I wrapped my content in a div (#outer-wrap) and then used the following CSS:

body {
   overflow: hidden;
}
#outer-wrap {
    -webkit-overflow-scrolling: touch;
     height: 100vh;
     overflow: auto;
}

Obviously only works in browsers that support viewport widths/heights of course.

There are a to of situations where the above CSS solutions do not work. For instance a transparent fixed header and a sticky footer on the same page. To prevent the top bounce in safari messing things and causing flashes on full screen sliders, you can use this.

    if (navigator.userAgent.indexOf('Safari') != -1 && navigator.userAgent.indexOf('Chrome') == -1) {

        $window.bind('mousewheel', function(e) {

            if (e.originalEvent.wheelDelta / 120 > 0) {

                if ($window.scrollTop() < 2) return false;
            } 
        });

    }
