Javascript Question

Run JavaScript code on window close or page refresh?

Is there a way to run a final JavaScript code when a user closes a browser window or refreshes the page?

I'm thinking of something similar to onload but more like onclose? Thanks.

I don't like the onbeforeunload method, which always yields to a confirmation box popping up (leave page/ stay on mozilla) or (reload/ don't reload on chrome). Is there a way to execute the code quietly?


Ok, I found a working solution for this, it consists of using the beforeunload event and then making the handler return null. This executes the wanted code without a confirmation box popping-up. It goes something like this:

window.onbeforeunload = closingCode;
function closingCode(){
   // do something...
   return null;

Hope this helps.
