不正确的旧答案：

arr.sort((a, b) => a.name > b.name)

更新

博尚的评论：

arr.sort((a, b) => a.name < b.name ? -1 : (a.name > b.name ? 1 : 0))

更可读的格式：

arr.sort((a, b) => {
  if (a.name < b.name) return -1
  return a.name > b.name ? 1 : 0
})

没有嵌套的三元组：

arr.sort((a, b) => a.name < b.name ? - 1 : Number(a.name > b.name))

说明：Number（）将强制为true，并强制为false。

我没有看到任何类似于我的实现。此版本基于施瓦茨变换习惯用法。

function sortByAttribute(array, ...attrs) {
  // Generate an array of predicate-objects containing
  // 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);
}

下面是如何使用它的示例：

let games = [
  { name: 'Mashraki',          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'));

一个按属性对对象数组进行排序的简单函数：

function sortArray(array, property, direction) {
    direction = direction || 1;
    array.sort(function compare(a, b) {
        let comparison = 0;
        if (a[property] > b[property]) {
            comparison = 1 * direction;
        } else if (a[property] < b[property]) {
            comparison = -1 * direction;
        }
        return comparison;
    });
    return array; // Chainable
}

用法：

var objs = [ 
    { first_nom: 'Lazslo', last_nom: 'Jamf'     },
    { first_nom: 'Pig',    last_nom: 'Bodine'   },
    { first_nom: 'Pirate', last_nom: 'Prentice' }
];

sortArray(objs, "last_nom"); // Asc
sortArray(objs, "last_nom", -1); // Desc

我知道已经有很多答案了，包括那些带有localeCompare的答案，但如果您出于某种原因不想/不能使用localeCompae，我建议您使用此解决方案，而不是三元运算符解决方案：

objects.sort((a, b) => (a.name > b.name) - (a.name < b.name));

有人可能会说，这段代码在做什么并不明显，但在我看来，三元运算符更糟糕。如果一个三元运算符足够可读，那么两个三元操作符一个嵌入另一个-真的很难读而且很难看。只有两个比较运算符和一个减号运算符的单行代码非常容易阅读，因此很容易推理。

我一直在各种项目中使用这个实用程序，而且效果很好。它也非常模块化：

传递要排序的键的名称选择排序是升序还是降序

按KeyUtil.js排序对象数组

// Sort array of objects by key
// ------------------------------------------------------------
const sortArrayOfObjsByKey = (array, key, ascdesc) =>
  array.sort((a, b) => {
    const x = a[key];
    const y = b[key];
    if (ascdesc === 'asc') {
      return x < y ? -1 : x > y ? 1 : 0;
    }
    if (ascdesc === 'desc') {
      return x > y ? -1 : x < y ? 1 : 0;
    }
    return null;
  });

按KeyUtil.test.js排序对象数组

import sortArrayOfObjsByKey from './sortArrayOfObjsByKeyUtil';

const unsortedArray = [
  {
    _id: '3df55221-ce5c-4147-8e14-32effede6133',
    title: 'Netlife Design',
    address: {
      PostalAddress: {
        streetAddress: 'Youngstorget 3',
        addressLocality: 'Oslo',
        addressRegion: null,
        postalCode: '0181',
        addressCountry: 'Norway',
      },
    },
    geopoint: { lat: 59.914322, lng: 10.749272 },
  },
  {
    _id: 'cd00459f-3755-49f1-8847-66591ef935b2',
    title: 'Home',
    address: {
      PostalAddress: {
        streetAddress: 'Stockfleths gate 58A',
        addressLocality: 'Oslo',
        addressRegion: null,
        postalCode: '0461',
        addressCountry: 'Norway',
      },
    },
    geopoint: { lat: 59.937316, lng: 10.751862 },
  },
];

const sortedArray = [
  {
    _id: 'cd00459f-3755-49f1-8847-66591ef935b2',
    title: 'Home',
    address: {
      PostalAddress: {
        streetAddress: 'Stockfleths gate 58A',
        addressLocality: 'Oslo',
        addressRegion: null,
        postalCode: '0461',
        addressCountry: 'Norway',
      },
    },
    geopoint: { lat: 59.937316, lng: 10.751862 },
  },
  {
    _id: '3df55221-ce5c-4147-8e14-32effede6133',
    title: 'Netlife Design',
    address: {
      PostalAddress: {
        streetAddress: 'Youngstorget 3',
        addressLocality: 'Oslo',
        addressRegion: null,
        postalCode: '0181',
        addressCountry: 'Norway',
      },
    },
    geopoint: { lat: 59.914322, lng: 10.749272 },
  },
];

describe('sortArrayOfObjsByKey', () => {
  it(`sort array by 'title' key, ascending`, () => {
    const testInput = sortArrayOfObjsByKey(unsortedArray, 'title', 'asc');
    const testOutput = sortedArray;
    expect(testInput).toEqual(testOutput);
  });
});

您还可以创建一个动态排序函数，根据传递的值对对象进行排序：

function dynamicSort(property) {
    var sortOrder = 1;
    if(property[0] === "-") {
        sortOrder = -1;
        property = property.substr(1);
    }
    return function (a,b) {
        /* next line works with strings and numbers, 
         * and you may want to customize it to your needs
         */
        var result = (a[property] < b[property]) ? -1 : (a[property] > b[property]) ? 1 : 0;
        return result * sortOrder;
    }
}

所以你可以有一个这样的对象数组：

var People = [
    {Name: "Name", Surname: "Surname"},
    {Name:"AAA", Surname:"ZZZ"},
    {Name: "Name", Surname: "AAA"}
];

…当你这样做时，它会起作用：

People.sort(dynamicSort("Name"));
People.sort(dynamicSort("Surname"));
People.sort(dynamicSort("-Surname"));

事实上，这已经回答了问题。下面的部分是因为许多人联系我，抱怨它不适用于多个参数。

多个参数

您可以使用下面的函数生成具有多个排序参数的排序函数。

function dynamicSortMultiple() {
    /*
     * save the arguments object as it will be overwritten
     * note that arguments object is an array-like object
     * consisting of the names of the properties to sort by
     */
    var props = arguments;
    return function (obj1, obj2) {
        var i = 0, result = 0, numberOfProperties = props.length;
        /* try getting a different result from 0 (equal)
         * as long as we have extra properties to compare
         */
        while(result === 0 && i < numberOfProperties) {
            result = dynamicSort(props[i])(obj1, obj2);
            i++;
        }
        return result;
    }
}

这将使您能够执行以下操作：

People.sort(dynamicSortMultiple("Name", "-Surname"));

子类化数组

对于我们中能够使用ES6的幸运者，ES6允许扩展本机对象：

class MyArray extends Array {
    sortBy(...args) {
        return this.sort(dynamicSortMultiple(...args));
    }
}

这将实现：

MyArray.from(People).sortBy("Name", "-Surname");
