I wrote a script that works on Greasemonkey extension to insert a link to a certain site. The problem is that it works only on the first page of that site. I need a script (Javascript only) that triggers a function when the URL is changed.

I find something related to location.hash but unfortunatelly it doesn't work for me.

var last_hash = "";

setInterval(function() {
hash = window.location.hash;

if(last_hash != hash && hash.length != 1) {
    processing();
    }
last_hash = window.location.hash;
}, 250);

Any ideas?

See the answers here: http://stackoverflow.com/questions/680785/on-window-location-hash-change - you shouldn't be running this in an interval. browsers can just listen on their own (I should say you shouldn't HAVE to run this in an interval. not saying it is specifically wrong) – Kai Qing Aug 13 '15 at 22:27
Like this `$(window).on('hashchange', function() { //.. work .. });`. – Praveen Kumar Purushothaman Aug 13 '15 at 22:32

@Praveen - right exactly, but with raw js it would be a little more verbose – Kai Qing Aug 13 '15 at 22:34
@KaiQing No buddy, don't say that. We have to give a lot of like: `window.onhashchange = function () {};`. But yeah, that's easy too! – Praveen Kumar Purushothaman Aug 13 '15 at 22:35
Thanks. I will check that. – Ace of Hz Aug 13 '15 at 22:38

@praveen - I bet you're right about that too. It's been a while since I did raw JS for this. For all I know all current browsers are equipped to handle that case (which actually looks LESS verbose) – Kai Qing Aug 13 '15 at 22:38
This is it. Thanks for help. – Ace of Hz Aug 13 '15 at 22:40
Yup. Sure... Enjoy! `:)` – Praveen Kumar Purushothaman Aug 13 '15 at 22:43
