Here's how you redirect a URL in JavaScript. Just set the value of window.location.replace to the URL you want.
<script type="text/javascript"> window.location.href = "http://www.url.com" </script>
When redirecting, window.location.replace is preferred over window.location.href.
// similar behavior as an HTTP redirect
window.location.replace("http://stackoverflow.com");
// similar behavior as clicking on a link
window.location.href = “http://stackoverflow.com”;
