• 1 And it's just within your own domain, no referrers from cross origins? You could maybe store the previous url in local storage or a cookie ? – adeneo Commented Apr 6, 2016 at 10:12
• 2 Is this just asking about referrals within your own site? Or from a different origin? – T.J. Crowder Commented Apr 6, 2016 at 10:13

How to get previous url including hash fragment using JavaScript?

As you've noted, the hash fragment part of that means you can't use document.referrer.

If the previous page was on the same origin: You'd need to have code on that page recording the full URL, for instance in sessionStorage.

On the previous page, perhaps each time hashChange is fired:

sessionStorage.setItem("last-url", location);

On the new page, to get the URL:

var lastUrl = sessionStorage.getItem("last-url");

If the previous page was on a different origin: I'm fairly certain you can't.

I need to get the previous url to redirect to the previous page.

Actually, you don't. You can just use history.go(-1) or history.back() to do that, which work regardless of the origin of the previous page.

May be you can use onhashchange event. When url is changed,it produces a event with old url and new url. The oldurl has even the hash part

try for previous url,

    function backtopage() {

    window.history.back();
}

$(window).bind('statechange',function(){
    // Prepare Variables
    var State = History.getState(),
        url = State.url,
        states = History.savedStates,
        prevUrlIndex = states.length - 2,
        prevUrl = states[prevUrlIndex].hash;
});

Try this one::

In previous page url:
www.mysite.com/users/register/#1

In Current Page:
$(document).ready(function() {
   var referrerUrl =   document.referrer.replace("#","e");
   var correctUrl=referrerUrl.replace("e","#");
});
