how to call data from function to Ajax? for update Laravel

I created record function to get data

function record(){
       SLTypeCPAMO_FLAG_ar: $('input[name="SLTypeCPAMO_FLAG_ar"]').val(),
      SLTypeRTI_FLAG_ar: $('input[name="SLTypeRTI_FLAG_ar"]').val(),
}

in ajax:

   data: { _token: '', sl:record() },

when i click update the success will appear but empty in database
