jquery – 打印json对象的键和值

我有2个外部json文件,我必须使用键和值从这些文件中读取数据.我的应用程序不依赖于obj.name等.请帮我打印这些值.

Planets.json

{
"Planets": [
  { "name": "Mercury","color": "Orange","distance": "57.91 km","radius": "2340 km","year": "0.24085 Earth","day": "88 days","mass": "0.054 Earth"
  },{ "name": "second","mass": "0.054 Earth"
  }

}

Airports.json

{
"Airports": [
  {
    "lisTing": "East 34th Street Heliport","iata": "TSS","type": "Heliport","size": "Tiny"
  }

}

这是我正在尝试的代码.

$.ajax({
                url:"planets.json",dataType: "json",success:function(json){
                    $.each(json,function(key,value){
                        console.log(key + ": " + value);
                    });
                }

            });

我把它放在控制台中

行星：[对象]

$.each(json.Planets[0],value){
    console.log(key + ": " + value);
});

$.each(json[Object.keys(json)[0]][0],value){
    console.log(key + ": " + value);
});

$.each(json,function(k,v){
    $.each(v[0],value){
        console.log(key + ": " + value);
    });
})

json[Object.keys(json)[0]].forEach(function(v){
    $.each(v,value){
        console.log(key + ": " + value);
    });
});

$.each(json,v){
    v.forEach(function(v1){  
        $.each(v1,value){
            console.log(key + ": " + value);
        });
    });
})
