Rails - Feb 2007 - AJAX status update to application just before a external site's button/link sends the user to another site ???

Hi,

I''m incorporating a Palpal donate button on my site, however
I''d like to be
able to send an update (AJAX) to my application to alert it to the fact that
the user has clicked on donate, and hence would be in the process of being
taken to the PayPal site.

Is there a way to wrap an AJAX update back to my application around an
external site''s link that I embed.

Tks
Greg

Take a look at how any popular web analytics package handles the
tracking of outclicks.  For example:

    http://s10.sitemeter.com/js/counter.asp     (Note: Copyright)

Basically, you add an onclick event handler to every link in the
document by iterating over document.links.

Ciao,
Sheldon.

Well they both support iterating over document elements (although
iterating over document.links is easy enough), and from there I''d
imagine it''s just the usual remote post handling.
