My current phosphate code

test.js

$(document).ready(function(){
    var scratch_player = $(".stage");
    var url = window.location.href;
    url = url.substr(33,40);
    $(scratch_player).empty();
    $(scratch_player).append("<script src='https://phosphorus.github.io/embed.js?id=", url, "&auto-start=false&light-content=false'></script>");
});
