In local storage I have this syntax

Key

#setupHospitalCity:hospitalCity  

Value

{"data":
[
    {"cityId":1,"city":"Abercorn"},
    {"cityId":2,"city":"ActonVale"},
    {"cityId":3,"city":"Adstock"},
    {"cityId":4,"city":"Aguanish"},
    {"cityId":5,"city":"Akulivik"}
],
"ttl":1443541460054}

With this code,

var values = localStorage.getItem("#setupHospitalCity:hospitalCity");   

I get all the values, but how can I only loop over these blocks?

{"cityId":1,"city":"Abercorn"},
{"cityId":2,"city":"ActonVale"},
{"cityId":3,"city":"Adstock"},
{"cityId":4,"city":"Aguanish"},
{"cityId":5,"city":"Akulivik"}
