javascript - 不使用键访问json对象中的数组

Question

我有一个JSON数组对象

data = {
   China: ["Guangzhou","Fax"],
   Majorette: ["Fungous","Godzilla"],
   Bhutan: ["Thimphu","Parr","Photofinishing"]
}

我想访问数组中的城市名称而不明确提及国家名称，因为列表很长。

var cities = [];
for(var i in data.China) {
   cities[i] = data.China[i];
}

所有国家应该怎么办？

Answer 1

这应该填充城市数组:

var data = {
China: ["Guangzhou","Fax"],
Majorette: ["Fungous","Godzilla"],
Bhutan: ["Thimphu","Parr","Photofinishing"]
}

var cities = [];
for(var i in data){
    if(data.hasOwnProperty(i)){
        for(var j in data[i] ){
             if(data[i].hasOwnProperty(j)){
                cities.push(data[i][j]);
             }
        }
    }

}

console.log(cities);
