Hey,
what I try to do is when a user clicked an image button on my
site, I use onClick to trigger a dialog box and at the same time I use
button.attach("onClick", savecookie) to mark this visitor so that next
time he comes back I can recognize him.If he did not click this image
button on my site, next time I would treat him as a new visitor.
My dialog box works as I expected but it seems that savecookie
function does not do its job since I could not find any cookies
stored. I am using IE7. Anyone has any idea about this? It means that
I cannot trigger two functions from one onclick?
