title: Is there a Javascript function to listen for new network events?
body: <p>I am trying to see if there is a 'DOMContentLoaded' equivalent of listening for other network events. For example, if the DOM is finished loading but the page loads dynamic content based on user interaction, can I track that new network event? Or at least know when one of those events occurs?</p>
  <p>Edit: I am specifically looking for a document wide event listener rather than just an event listener for a single element.</p>
