URL Change Event - JavaScript

Question

I have a setTimeout that records the URL in a variable called newURL.

function checkURL() {
    var newURL = window.location;
} setInterval(checkURL, 1000);

What I would like to happen, is that a certain function must be executed, when the URL changes. Could someone help me here please?

Not sure why the page wouldn't reload before you could catch the change in the url. You can also take a look a window.onunload

var checkURL = (function () {
    var oldURL = location.href;
    return function (fn) {
        var newURL = location.href;
        if (fn && oldURL !== newURL) {
            fn(oldURL, newURL);
        }
        oldURL = newURL;
    };
}());
