මේකේ, routesOutput කියන array එක ඇතුලේ weekly කියල තව array එකක් තියෙනව. ඒක ඇතුලේ flight_ids කියල එකක් තියෙනව. මේ පහල විධියට.

• routesOutput[0].schedules.weekly[0].flights.flight_ids

ඒ වගේම, schedulesOutput කියන array එක ඇතුලේත් flight_ids කියල තියේනව. මේ පහල විධියටම.

• schedulesOutput[0].flights.flight_ids

මම for loops පාවිච්චි කරල , ඒවා loop කරල, arrays 2ම එක සමාන flight_ids තියේන ඒවා අරගෙන, ඒවා එක array එකකට push කරා. නමුත්, routesOutput[0].schedules.weekly[0].flights.flight_ids[0] හා [1] එකම element එකකට push කරන්න තමයි මට ඕන.

මෙහම තමයි මට ලැබුනේ.

[
  {
    "ori_sub_origin": "CMB",
    "ori_sub_desti": "MLE"
  },
   {
    "desti_sub_origin": "MLE",
    "desti_sub_desti": "IST"
  },
 ]

මේ විධියටයි මට ඕන වෙන්නේ.

    "ori_sub_origin": "CMB",
    "ori_sub_desti": "MLE",
    "desti_sub_origin": "MLE",

  }
 ]

මෙන්න මගේ කෝඩ් එක.
