Question

How can I capture a new request (e.g. link click, page refresh, etc.) in an html page?

Let’s say I need to do some stuff when user decides to go to another page or refresh the current page.

Answer 1

Look at the the window.onbeforeunload and window.onunload events

You can also capture any link clinks easily [jQuery sample]:

$('a').on('click', function() {
     // do your stuff

     // follow the link
     window.location.href = this.href;
});
