Ajax and custom parameters - howto/best practice?

I've been rewriting a user management backend for a CMS system. The system has a very large number of users, and in the pre-Datatables version we've had an option to filter by "groups" and the account state.

In past uses of Datatables with a similar use-case I've reloaded the page, but I'd really like set pass the value to the Ajax Call and reload/redraw the table with fresh data.

In the Datatables version I'm using an Ajax-backed for all table data, and I would like to be able to pass parameters along with the Ajax-calls when they're set.

Is it possible?

    The code is quite similar to the example here:
    http://datatables.net/1.5-beta/examples/data_sources/server_side.html

    In this case, I'd like to be able to pass a value (through) to the ajax call to restrict the results to only include Windows browsers.

    Hi mahler,

    You can add custom variables to the get request as shown in this demo: http://datatables.net/1.5-beta/examples/server_side/custom_vars.html

    Thank, it was just the example I needed :)

    Tips for others with a similar need...

    I added the "fnServerData" from the custom_vars example, and changed the array passed ind the aoData.push to contain the selected values from the two drop-downs. That was fine, but the table also needed to reload the data once the values for the dropdowns changed.

    To fix this I had to add the fnReloadAjax plugin available here http://datatables.net/plug-ins#extras - and attached to the change-event on the two dropdowns with state and group, but once that was in place, everything works just fine.
