JavaScript: Change Page Title in Browser dynamically

If you want to change the title of a website dynamically using JavaScript, you can just use this simple line:

<script type="text/javascript">
  document.title = 'My New Title';
</script>

You only have to set a string to "document.title" and the title shown in the browser is changing.

Please note: it is not a good idea to use this function for search engine optimization (SEO) reasons, because most search engines are ignoring JavaScript, so that this script does not have any effect. But of course, you can use the script to give users a better orientation when dynamically changing the content of the web page.
