通过添加两个辅助函数，可以简单地解决这类问题。sortByKey接受一个数组和一个函数，该函数应返回一个项目列表，用于与每个数组条目进行比较。

这利用了javascript对简单值的数组进行智能比较的事实，即[2]<[2,0]<[2,1]<[10,0]。

// Two helpers: function cmp(a, b) { if (a > b) { return 1 } else if (a < b) { return -1 } else { return 0 } } function sortByKey(arr, key) { arr.sort((a, b) => cmp(key(a), key(b))) } // A demonstration: let arr = [{a:1, b:2}, {b:3, a:0}, {a:1, b:1}, {a:2, b:2}, {a:2, b:1}, {a:1, b:10}] sortByKey(arr, item => [item.a, item.b]) console.log(JSON.stringify(arr)) // '[{"b":3,"a":0},{"a":1,"b":1},{"a":1,"b":10},{"a":1,"b":2},{"a":2,"b":1},{"a":2,"b":2}]' sortByKey(arr, item => [item.b, item.a]) console.log(JSON.stringify(arr)) // '[{"a":1,"b":1},{"a":2,"b":1},{"a":1,"b":10},{"a":1,"b":2},{"a":2,"b":2},{"b":3,"a":0}]'

我从Python的列表中偷取了这个想法。排序功能。

只需遵循排序标准列表

即使要封装36个排序标准，这段代码也将始终保持可读和可理解

Nina在这里提出的解决方案当然非常优雅，但它意味着要知道在布尔逻辑中，值为0对应的值为false，并且布尔测试在JavaScript中可以返回除true / false以外的值(这里是数值)，这对于初学者来说总是令人困惑。

还要考虑谁需要维护您的代码。也许会是你:想象一下你自己花了几天的时间在另一个人的代码上，然后有了一个有害的错误……你读了几千行充满技巧的文章，都累坏了

const 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: '6', city: 'Dallas', state: 'TX', zip: '75000', price: '556699' } , { h_id: '5', city: 'New York', state: 'NY', zip: '00010', price: '962500' } ] const fSort = (a,b) => { let Dx = a.city.localeCompare(b.city) // 1st criteria if (Dx===0) Dx = Number(b.price) - Number(a.price) // 2nd // if (Dx===0) Dx = ... // 3rd // if (Dx===0) Dx = ... // 4th.... return Dx } console.log( homes.sort(fSort))

另一种方式

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":"6", "city":"Dallas", "state":"TX", "zip":"75000", "price":"556699"}, {"h_id":"5", "city":"New York", "state":"NY", "zip":"00010", "price":"962500"} ]; function sortBy(ar) { return ar.sort((a, b) => a.city === b.city ? b.price.toString().localeCompare(a.price) : a.city.toString().localeCompare(b.city)); } console.log(sortBy(homes));

对于你的具体问题，一个非通用的，简单的解决方案:

homes.sort(
   function(a, b) {          
      if (a.city === b.city) {
         // Price is only important when cities are the same
         return b.price - a.price;
      }
      return a.city > b.city ? 1 : -1;
   });

您可以使用链式排序方法，取值的增量，直到它达到不等于零的值。

var data = [{ 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: "6", city: "Dallas", state: "TX", zip: "75000", price: "556699" }, { h_id: "5", city: "New York", state: "NY", zip: "00010", price: "962500" }]; data.sort(function (a, b) { return a.city.localeCompare(b.city) || b.price - a.price; }); console.log(data); .as-console-wrapper { max-height: 100% !important; top: 0; }

或者，使用es6，简单地:

data.sort((a, b) => a.city.localeCompare(b.city) || b.price - a.price);

下面是我基于施瓦兹变换的解决方案，希望你觉得有用。

function sortByAttribute(array, ...attrs) {
  // generate an array of predicate-objects contains
  // property getter, and descending indicator
  let predicates = attrs.map(pred => {
    let descending = pred.charAt(0) === '-' ? -1 : 1;
    pred = pred.replace(/^-/, '');
    return {
      getter: o => o[pred],
      descend: descending
    };
  });
  // schwartzian transform idiom implementation. aka: "decorate-sort-undecorate"
  return array.map(item => {
    return {
      src: item,
      compareValues: predicates.map(predicate => predicate.getter(item))
    };
  })
  .sort((o1, o2) => {
    let i = -1, result = 0;
    while (++i < predicates.length) {
      if (o1.compareValues[i] < o2.compareValues[i]) result = -1;
      if (o1.compareValues[i] > o2.compareValues[i]) result = 1;
      if (result *= predicates[i].descend) break;
    }
    return result;
  })
  .map(item => item.src);
}

下面是一个如何使用它的例子:

let games = [
  { name: 'Pako',              rating: 4.21 },
  { name: 'Hill Climb Racing', rating: 3.88 },
  { name: 'Angry Birds Space', rating: 3.88 },
  { name: 'Badland',           rating: 4.33 }
];

// sort by one attribute
console.log(sortByAttribute(games, 'name'));
// sort by mupltiple attributes
console.log(sortByAttribute(games, '-rating', 'name'));
