我使用Ajax读取以下对象并将它们存储在一个数组中:

var homes = [
    {
        "h_id": "3",
        "city": "Dallas",
        "state": "TX",
        "zip": "75201",
        "price": "162500"
    }, {
        "h_id": "4",
        "city": "Bevery Hills",
        "state": "CA",
        "zip": "90210",
        "price": "319250"
    }, {
        "h_id": "5",
        "city": "New York",
        "state": "NY",
        "zip": "00010",
        "price": "962500"
    }
];

如何使用JavaScript 创建一个函数来按price属性按升序 或 降序对对象进行排序？

我有一个数组(请参阅下面的数组中的一个对象),我需要使用JavaScript对firstname进行排序.我该怎么做？

var user = {
   bio: null,
   email:  "user@domain.com",
   firstname: "Anna",
   id: 318,
   lastAvatar: null,
   lastMessage: null,
   lastname: "Nickson",
   nickname: "anny"
};

这是我的JSON文件的一个例子.

[
    {"Variable":"Hello","Variable1":20}, {"Variable":"Hi","Variable1":30},
    {"Variable":"How","Variable1":40}, {"Variable":"Who","Variable1":50},
    {"Variable":"Where","Variable1":60}, {"Variable":"This","Variable1":100},
    {"Variable":"Pork","Variable1":10}, {"Variable":"Creep","Variable1":90},
    {"Variable":"Mega Creeps","Variable1":80}, {"Variable":"LOL","Variable1":0},
    {"Variable":"ROFL","Variable1":0}, {"Variable":"LMAO","Variable1":0},
    {"Variable":"POP","Variable1":0}, {"Variable":"LOVE","Variable1":0},
    {"Variable":"PICK","Variable1":0}, {"Variable":"WHIZ","Variable1":0},
    {"Variable":"BORED","Variable1":0}, {"Variable":"KILLAH","Variable1":0},
    {"Variable":"LOLLING","Variable1":0}, {"Variable":"HALOO  HALOO","Variable1":0}
]

如何才能从最高的Variable1号码中获得前10名？但是要将JSON文件作为相同的格式传递.

这是我从foursquare获得的JSON的一部分.

JSON

tips: {
    count: 2,
    groups: [
    {
        type: "others",
        name: "Tips from others",
        count: 2,
        items: [
        {
            id: "4e53cf1e7d8b8e9188e20f00",
            createdAt: 1314115358,
            text: "najja?i fitness centar u gradu",
            canonicalUrl: "https://foursquare.com/item/4e53cf1e7d8b8e9188e20f00",
            likes: {
                count: 2,
                groups: [
                {
                    type: "others",
                    count: 2,
                    items: []
                }],
                summary: "2 likes"
            },
            like: false,
            logView: true,
            todo: {
                count: 0
            },
            user: {
                id: "12855147",
                firstName: "Damir",
                lastName: "P.",
                gender: "male",
                photo: {
                    prefix: "https://irs1.4sqi.net/img/user/",
                    suffix: "/AYJWDN42LMGGD2QE.jpg"
                }
            }
        },
        {
            id: …

我需要以角度,字母顺序(升序)对列表进行排序,但是如果要在列表末尾推送项目的前缀,则需要特殊字符.例如:列表应该像:

Apple
Banana
*Apple

建议任何建议.

我有以下JSON树:

[
  {
    "category":"PASTAS",
    "createdAt":"2016-01-01T19:47:57.813Z",
    "currency":"$",
    "dishName":"Spaghetti",
    "estTime":"10-20 min",
    "price":10,
    "subName":"Pasta",
    "updatedAt":"2016-04-28T20:48:06.800Z"
  },
  {
    "category":"PIZZAS",
    "createdAt":"2016-04-19T21:44:56.285Z",
    "currency":"$",
    "dishName":"Ai Funghi Pizza ",
    "estTime":"20-30 min",
    "price":20,
    "subName":"Pizza",
    "updatedAt":"2016-04-28T20:58:39.499Z"
  },
  {
    "category":"PIZZAS",
    "createdAt":"2016-04-19T21:44:56.285Z",
    "currency":"$",
    "dishName":"Seafood Pizza",
    "estTime":"20-30 min",
    "price":10,
    "subName":"Pizza",
    "updatedAt":"2016-04-28T20:58:39.499Z"
  }
]

正如您在JSON树中看到的那样,元素category:"PIZZAS"重复两次,我想要做的是创建一个新数组或组织这些结果以避免在所有其他重复项中重复,即在上面的示例中,会得到这样的最终结果:

 Pastas:
 Spaghetti

 Pizza:
 Ai Fungi Pizza,
 Seafood Pizza

关于如何实现想要结果的任何想法？
