To get my data, I need to make a chain of Ajax calls to an API, where the 1st call gets a parameter that needs to be sent in the 2nd call, and where the 2nd call gets a parameter that needs to be sent in the 3rd call and so on... When I've gotten all the necessary filter parameters, I can make like the 5th and last call to receive my filtered data. THEN I want to append it to the table. Meanwhile, I want DataTable to show "Loading" as it does for a singel Ajax call.
How do I do this?
