I am trying to put the Back Button Redirect Script function to good use. I have a plugin which plays background (user-initiated) music on my site. As long as the user clicks forward, the music streams continuously and nearly uninterrupted from page to page, without restarting. If the user clicks the back button (or refreshes), the music stops and they must manually press play to restart the stream. The author says they have no way to resolve it. I'm not giving up just yet.

My thought is, why not use JavaScript to record the browser's previous page URL, then capture the back button trigger and send the user "forward" to that URL, thus keeping the music stream intact while honoring the user's desire to go back a page?

Conceptually, being a supernoob at JavaScript, I patched this together from different sources on here and codingbeautydev...

$(window).bind("onpopstate", function (e) {
    const previousPage = document.getElementById("previous-page");
    previousPage.textContent = document.referrer;

    window.history.pushState({ page: 1 }, "", "");
    window.onpopstate = function (event) {
        if (event) {
            window.location.href = previousPage;
        }
    };
});

My first thought is there are surely some syntex errors in there at my doing and potentially much more that need be modified, but I'm hoping someone can easily touch up my rough sketch. Additionally, beyond making this work, I see the limits of this allowing only 1-page of history, and I'm curious if there's a way to nest it into a stack of a few pages to which could be visited in reverse order, all the while moving "forward". First things first though, then on to bigger and better.

Thanks guys!
