What you have is a unparsed object, You can use JSON.parse() to parse it and get a object.

var obj = JSON.parse('{ "sEcho": 1, "iTotalRecords": 54, "iTotalDisplayRecords": 54, "aaData": [ [ "79", "testowy2", "testowy samochod", "12.00", "14.00", "2147483647", "posciel", "" ] ] }');

How I can display data from 1st post?

Sergio Over a year ago

@user3211948, then you can use obj.sEcho, or obj.iTotalRecords- did you check my demo?

Yes I checked it displays data in aaData but how I can separate each value in this data?

Sergio Over a year ago

@user3211948 Since aaData is a array with a array inside, you first need to use aaData[0] to reach the inner array, then use numbers from 0 to reach the one you want. For example aaData[0][3] will give you "12.00"

It works thanks. Can you tell me one more thing. How can I check how many arrays are in aaData?
