How to tell if a page has been reloaded in Firebug or Chrome Developer tools?

Question

I have a page where if I select an entry from a drop down menu, part of the page flickers and the url changes. I didn't write the code for this page but I think it did something in the background to load or reload at least part of itself.

But when I look in the Network tab of Chrome developer tools or Firebug, I don't see a network call to the new url. So how could the url of the page change without a network call being shown in these tools?

Is there a way to tell with either of these tools if window.onload or document.ready has fired at this point?

Answer 1

You can use breakpoints on event listeners to see if certain events are triggered or not. See the documentation.

Or, Chrome devtools can list the event handlers registered on any element. Just inspect the element and expand the Event Listeners panel.
