How can I retain the scroll position of a scrollable area when pressing back button?

Question

I have a long list of links inside a big scrollable div. Each time when a user click on a link then click the back button, it starts at the very top of the div. It is not user friendly to our users. Any ways to let the browser scroll to the previous position when pressing the back button?

Thank you very much!

Answer 1

During page unload, get the scroll position and store it in local storage. Then during page load, check local storage and set that scroll position. Assuming you have a div element with id element. In case it's for the page, please change the selector :)

$(function() {    $(window).unload(function() {       var scrollPosition = $("div#element").scrollTop();       localStorage.setItem("scrollPosition", scrollPosition);    });    if(localStorage.scrollPosition) {       $("div#element").scrollTop(localStorage.getItem("scrollPosition"));    } });

I think we should save scroll data per page, also we should use session storage instead of local storage since session storge effects only the current tab while local storage shared between all tabs and windows of the same origin

$(function () {
            var pathName = document.location.pathname;
            window.onbeforeunload = function () {
                var scrollPosition = $(document).scrollTop();
                sessionStorage.setItem("scrollPosition_" + pathName, scrollPosition.toString());
            }
            if (sessionStorage["scrollPosition_" + pathName]) {
                $(document).scrollTop(sessionStorage.getItem("scrollPosition_" + pathName));
            }
        });

I had the same problem with a simple user interface consisting of a fixed menu div and a scrolling document div ("pxeMainDiv" in the code example below). The following solution worked for me in Chrome 47.0.2526.106 m and in Firefox 43.0.3. (My application is for use in-house and I did not need to cater for old versions of IE).

$(document).ready(function(){
    if (history.state) {
       $("#pxeMainDiv").scrollTop(history.state.data);
    }
    $("#pxeMainDiv").scroll(function() {
       var scrollPos = $("#pxeMainDiv").scrollTop();
       var stateObj = { data: scrollPos };
       history.replaceState(stateObj, "");
    });
});

On the div scroll event, the scroll position of the div is stored in the state object inside the browser history object. Following a press of the Back button, on the document ready event, the scroll position of the div is restored to the value retrieved from the history.state object.

This solution should work for the reverse navigation of an arbitrarily long chain of links.
