I have a grails application with a http-link to a controller export method. This creates an excel-file and send it to the browser. This can take several minutes.
I now creates a spinner.gif and show this when the user clicks on the export link via $('#wait').show();. This spinner blocks the whole application! (that was the plan :-) )
The problem now is, how can I hide the spinner again. I found no method in JQuery with can be handle the event "Excel-File was sent to browser".
Even when I try to redirect the page after the export call in the controller, I get an error, because there might be only one answer (document) sent to the requesting browser.
Is there an easy way, if any?
