How do I parse JSON Data in a loop?

{"realms":[{"type":"rp","population":"medium","queue":false,"wintergrasp":{"area":1,"controlling-faction":1,"status":0,"next":1462710723768},"tol-barad":{"area":21,"controlling-faction":0,"status":1,"next":1462710700949},"status":true,"name":"Zirkel des Cenarius","slug":"zirkel-des-cenarius","battlegroup":"Embuscade / Hinterhalt","locale":"de_DE","timezone":"Europe/Paris","connected_realms":["zirkel-des-cenarius","todeswache"]}]}
[/code:t1iilrg9]

example for multiple realms:
[code:t1iilrg9]{"realms":[{"type":"pvp","population":"high","queue":false,"wintergrasp":{"area":1,"controlling-faction":0,"status":0,"next":1462710732001},"tol-barad":{"area":21,"controlling-faction":0,"status":0,"next":1462712427270},"status":true,"name":"Aegwynn","slug":"aegwynn","battlegroup":"Misery","locale":"de_DE","timezone":"Europe/Paris","connected_realms":["aegwynn"]},{"type":"pve","population":"medium","queue":false,"wintergrasp":{"area":1,"controlling-faction":1,"status":0,"next":1462710724874},"tol-barad":{"area":21,"controlling-faction":1,"status":1,"next":1462710703055},"status":true,"name":"Aerie Peak","slug":"aerie-peak","battlegroup":"Reckoning / Abrechnung","locale":"en_GB","timezone":"Europe/Paris","connected_realms":["bronzebeard","aerie-peak"]},{"type":"pvp","population":"medium","queue":false,"wintergrasp":{"area":1,"controlling-faction":0,"status":0,"next":1462710910703},"tol-barad":{"area":21,"controlling-faction":0,"status":1,"next":1462710887883},"status":true,"name":"Agamaggan","slug":"agamaggan","battlegroup":"Reckoning / Abrechnung","locale":"en_GB","timezone":"Europe/Paris","connected_realms":["agamaggan","crushridge","bloodscalp","twilights-hammer","hakkar","emeriss"]}
[/code:t1iilrg9]

I tried  but I get an error when I try to load the AJAX data.

[i]also..[/i]perhaps would be better to write json for multiple realms
like this:
[code:2gfer4bq]{

      },
      "tol-barad": {
        "area": 21,
        "controlling-faction": 0,
