Question

I am javascript newbie. I need to collect the packet traces for a webpage by reloading it in the same tab every 30 seconds. How can I do this using javascript?

Answer 1

You can either use a HTML only solution:

<meta http-equiv="refresh" content="30; URL=http://www.yourdomain.com/yoursite.html">

Or use Javascript:

setTimeout(function(){
   window.location.reload(1);
}, 30000);

Both ways refresh the current page every 30 seconds. Right from MDC:

Reload the document from the current
URL. forceget is a boolean, which,
when it is true, causes the page to
always be reloaded from the server. If
it is false or not specified, the
browser may reload the page from its
cache.
