Hi Joel!
Than for your detailed JavaScript help. However, as you have also pointed
out, my requirement is to have tool-tip sort of thing for the generated on
dynamically generated code, including hyperlinks and images.
I hope somebody will be able to throw some light on it. You can get the
details of this query at ND forums by searching for tool tip text.
Thanx.
