Getting and evaluation additional data from server reply

Phil1881

Hello everybody!

First of all: Thanks for this great tool. I really like it!

I created a nice table with server side processing and a separate form with advanced search options. Thanks to the function fnServerParams I can add these extra parameters to the request.

Some input fields need to be validated by the server. I would like to return an error message to the client if this failed. Simply imagine a date input...

Is there a JS function call with which I can interpret the server reply?

Thanks for your ideas!

Yes, listening for the `xhr` event is currently the easiest option - http://datatables.net/docs/DataTables/1.9.4/#xhr . The other option is to override fnServerData .

Hi Allan,

thanks a lot for your fast answer.

I'm asking myself why I didn't find the documentation linked in your answer (http://datatables.net/docs/DataTables/1.9.4/). It's explaining many questions I had and answered myself by try and error. Why don't you link these docs more prominently?
