Server-side processing, possible to return addition page.info() data?

dnorman

I am using custom server-side processing for some tables with DataTables 1.10.15.

Is it possible to have the server supply extra information to the page.info() API?

Like how recordsFiltered on the server translates to recordsDisplay in page.info().

I maintaining a "selected" state of all the selected rows on the server and would like to return a recordsSelected amount along with the typical server-side data that gets sent back.

e.g.

    {
    draw: 1,
    recordsTotal: 10000,
    recordsFiltered: 500,
    recordsSelected: 25,
    data: {}
    }

I see that in fnDrawCallback I can access the oSettings.json to retrieve the data (oSettings.json.recordsSelected) but I would like to make it part of the page.info() data to be used elsewhere outside of fnDrawCallback.

You can use ajax.json() to get the last JSON response at anytime you like. You can use the xhr event to retrieve the JSON response once its received.

Excellent, thank you, that does exactly what I am looking for! Wow, I overlooked that, right at the top of the API docs too.
