Loading JSON file into script variable

Question

I have a JSON file with city names and their ids. I want to load only the city names into a script variable so I can use that variable as a source in autocomplete for jQuery.

Data Example:

{
    "cities": [
        {
            "id": 1440,
            "name": "Bundi"
        },
        {
            "id": 850,
            "name": "Beed"
        },
        {
            "id": 1409,
            "name": "Kankroli"
        },
        {
            "id": 1913,
            "name": "Muniyal Herbals And Ayurvedic Remedies Limited"
        },
        {
            "id": 2418,
            "name": "Kunnicode"
        }]
}

names = cities.map(function(v){ return v.name })

var someVar = JSON.parse(someStringContainingYourJSON) 


someVar.cities[0].id.. etc
someVar.cities[1].id

or you can use

$.getJSON('/url',function(someVar){
   someVar.cities[0].id.. etc
    someVar.cities[1].id

})
