How can I detect what messages have been "alerted" by javascript?

I'd like a way to detect when a message alerts to the browser and what the message is.  How can I do this?

Basically I want the page to refresh if a certain message ever gets alerted/popped up in the browser.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.


Try something like this:

<meta http-equiv="X-UA-Compatible" content="IE=8" />
<script src="" type="text/javascript"></script>

var nativeAlert = window.alert;
window.alert = overrideAlert;

function overrideAlert( message ) {
  var last = $(".dialog:last");
  var entry = last.clone().show();
  $("fieldset", entry).append( message );
  $("fieldset>legend", entry).text( new Date().toString() );
  last.before( entry );

  nativeAlert( "*"+message );


  alert( "Hello World" );
  alert( "Goodbye cruel world" );



<div class="dialog" style="display:none;">

Forgive my ignorance but I really don't even know how to use that.  I placed that on the page and it displayed messages when I had an alert popup and also when I didn't have an alert popup.
