I am trying to retrieve the scroll position when a user navigates back in the browser history using HTML5 popstate handler.
Here is what I have:
$(document).ready(function () {
$(window).on('popstate', PopStateHandler);
$('#link').click(function (e) {
var stateData = {
path: window.location.href,
scrollTop: $(window).scrollTop()
};
window.history.pushState(stateData, 'title', 'page2.html');
e.preventDefault();
});
});
function PopStateHandler(e) {
alert('pop state fired');
var stateData = e.originalEvent.state;
if (stateData) {
//Get values:
alert('path: ' + stateData.path);
alert('scrollTop: ' + stateData.scrollTop);
}
}
<a id="link" href="page2.html"></a>
When I navigate back, I am unable to retrieve the values of the stateData.
I presume this is because the popstate is retrieving the values of the initial page load and not the state I pushed to the history when the hyperlink was clicked.
How could I go about getting the scroll position on navigating back?
