let propName = 'last_nom';

let sorted_obj = objs.sort((a,b) => {
    if(a[propName] > b[propName]) {
        return 1;
    }
    if (a[propName] < b[propName]) {
        return -1;
    }
    return 0;
}

//This works because the js built-in sort function allows us to define our
//own way of sorting, this funny looking function is simply telling `sort` how to
//determine what is larger. 
//We can use `if(a[propName] > b[propName])` because string comparison is already built into JS
//if you try console.log('a' > 'z' ? 'a' : 'z')
//the output will be 'z' as 'a' is not greater than 'z'
//The return values 0,-1,1 are how we tell JS what to sort on. We're sorting on the last_nom property of the object. 
//When sorting a list it comes down to comparing two items and how to determine which one of them is "larger". 
//We need a way to tell JS how to determine which one is larger. 
//The sort defining function will use the case that returns a 1 to mean that a > b
//and the case that returns -1 to mean that a < b

我还没有看到这种特别的方法，所以这里有一个我喜欢使用的简洁的比较方法，它适用于字符串和数字类型：

常量对象=[{first_nom:'Lazslo'，last_nom:'Jamf'}，{first_nom:'猪'，last_nom:'Bodine'}，｛first_nom:'海盗'，last_nom:'Prentice'｝];常量排序依据=fn=>{常量cmp=（a，b）=>-（a<b）||+（a>b）；return（a，b）=>cmp（fn（a），fn（b））；};const getLastName=o=>o.last_nom；const sortByLastName=sortBy（getLastName）；objs.sort（sortByLastName）；console.log（objs.map（getLastName））；

sortBy（）的解释

sortBy（）接受一个fn，该fn从一个对象中选择一个值用于比较，并返回一个可以传递给Array.prototype.sort（）的函数。在本例中，我们正在比较o.last_nom。每当我们收到两个对象，例如

a = { first_nom: 'Lazslo', last_nom: 'Jamf' }
b = { first_nom: 'Pig', last_nom: 'Bodine' }

我们将它们与（a，b）=>cmp（fn（a），fn（b））进行比较。鉴于此

fn = o => o.last_nom

我们可以将比较函数扩展为（a，b）=>cmp（a.last_nom，b.last_nom）。由于逻辑OR（||）在JavaScript中的工作方式，cmp（a.last_nom、b.last_nom）相当于

if (a.last_nom < b.last_nom) return -1;
if (a.last_nom > b.last_nom) return 1;
return 0;

顺便说一下，这在其他语言中被称为三向比较“宇宙飞船”（<=>）运算符。

最后，这里是不使用箭头函数的ES5兼容语法：

var对象=[{first_nom:'Lazslo'，last_nom:'Jamf'}，{first_nom:'猪'，last_nom:'Bodine'}，｛first_nom:'海盗'，last_nom:'Prentice'｝];函数sortBy（fn）{函数cmp（a，b）{return-（a＜b）| |+（a＞b）；}返回函数（a，b）{return cmp（fn（a），fn（b））；}；}函数getLastName（o）｛return o.last_nom；｝var sortByLastName=sortBy（getLastName）；objs.sort（sortByLastName）；console.log（objs.map（getLastName））；

示例用法：

objs.sort(sortBy('last_nom'));

脚本：

/**
 * @description
 * Returns a function which will sort an
 * array of objects by the given key.
 *
 * @param  {String}  key
 * @param  {Boolean} reverse
 * @return {Function}
 */
const sortBy = (key, reverse) => {

  // Move smaller items towards the front
  // or back of the array depending on if
  // we want to sort the array in reverse
  // order or not.
  const moveSmaller = reverse ? 1 : -1;

  // Move larger items towards the front
  // or back of the array depending on if
  // we want to sort the array in reverse
  // order or not.
  const moveLarger = reverse ? -1 : 1;

  /**
   * @param  {*} a
   * @param  {*} b
   * @return {Number}
   */
  return (a, b) => {
    if (a[key] < b[key]) {
      return moveSmaller;
    }
    if (a[key] > b[key]) {
      return moveLarger;
    }
    return 0;
  };
};

如果您有嵌套对象

const objs = [{
        first_nom: 'Lazslo',
        last_nom: 'Jamf',
        moreDetails: {
            age: 20
        }
    }, {
        first_nom: 'Pig',
        last_nom: 'Bodine',
        moreDetails: {
            age: 21
        }
    }, {
        first_nom: 'Pirate',
        last_nom: 'Prentice',
        moreDetails: {
            age: 22
        }
    }];

nestedSort = (prop1, prop2 = null, direction = 'asc') => (e1, e2) => {
        const a = prop2 ? e1[prop1][prop2] : e1[prop1],
            b = prop2 ? e2[prop1][prop2] : e2[prop1],
            sortOrder = direction === "asc" ? 1 : -1
        return (a < b) ? -sortOrder : (a > b) ? sortOrder : 0;
    }

并称之为

objs.sort(nestedSort("last_nom"));
objs.sort(nestedSort("last_nom", null, "desc"));
objs.sort(nestedSort("moreDetails", "age"));
objs.sort(nestedSort("moreDetails", "age", "desc"));

试试看：

ES5之前

// Ascending sort
items.sort(function (a, b) {
   return a.value - b.value;
});


// Descending sort
items.sort(function (a, b) {
   return b.value - a.value;
});

ES6及以上

// Ascending sort
items.sort((a, b) => a.value - b.value);

// Descending sort
items.sort((a, b) => b.value - a.value);

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");
