Yes, a save dialog.
Just a normal standard download but, as there is some time consuming
processing related to the download, I want some busy icon to tell the user
that something is happening. There not all so good to see the browser
status bar and they click again and again until the save dialog box finally
pop up.
Maybe a normal link with some ajax events to control the link icon could do
it. Chang to busy icon when "onclik" and change it back when "onload" .
Could that do it ?
Javascript and ajax is not my strong side, any suggestion appreciated.
Thanks.
