Retain scrollbar position even after reloading using javascript

You can use session storage to store the position then get back to the position when the page is reloaded, like this:

$(window).scroll(function() {
  sessionStorage.scrollTop = $(this).scrollTop();
});

$(document).ready(function() {
  if (sessionStorage.scrollTop != "undefined") {
    $(window).scrollTop(sessionStorage.scrollTop);
  }
});

Here is the JSFiddle demo
