我有这个对象数组:
var vigilantes = [
{
"fullName": "Tony Stark",
"classRoom": "XI",
"city": "NYC",
"job": "Engineer",
"studies": "MIT",
"markAV": 10,
},
{
"fullName": "Hulk Green",
"classRoom": "IV",
"city": "Beijing",
"job": "Physicist",
"studies": "Harvard",
"markAV": 9,
},
{
"fullName": "Thor Norse",
"classRoom": "XX",
"city": "Oslo",
"job": "God",
"studies": "U of Norway",
"markAV": 8.5,
},
{
"fullName": "Bruce Wayne",
"classRoom": "XIX",
"city": "Gotham",
"job": "Richamn",
"studies": "U of Gotham",
"markAV": 8,
},
{
"fullName": "Peter Parker",
"classRoom": "XI",
"city": "NYC",
"job": "Photographer",
"studies": "Syracuse U",
"markAV": 7.5,
}
]
我想按城市过滤它,但我需要创建一个包含共享同一城市的对象的新数组。在此示例中,所需的结果将是两个对象的数组,因为它们将NYC共享为城市:
var vigilantes = [
{
"fullName": "Tony Stark",
"classRoom": "XI",
"city": "NYC",
"job": "Engineer",
"studies": "MIT",
"markAV": 10,
},
{
"fullName": "Peter Parker",
"classRoom": "XI",
"city": "NYC",
"job": "Photographer",
"studies": "Syracuse U",
"markAV": 7.5,
}
]
我知道我可以按照这样过滤城市:
var nyc = "NYC"
var oslo = "Oslo"
var gotham = "Gotham"
var beijing = "Beijing"
var res = vigilantes.filter(function (vigilante) {
return beijing.indexOf(vigilante.city) >= 0;
});
但我正在寻找更轻松的事情!
非常感谢你的帮助,因为你可以看到我是编程方面的新手!

您可以将哈希表作为对具有相同城市的数组的引用。
.as-console-wrapper { max-height: 100% !important; top: 0; }
