I have some links that when the user clicks one, it links to a php script which runs some stored procedures to generate data and then calls another script to download the data as an excel spreadsheet. This all works fine.
What I'd like to do is have a loader gif appear beside the link that was clicked clicked and when the dialog appears to get the user to save the file, have that gif disappear again.
Can I track this event at all to achieve this? Not had much luck so far.
