对对象数组进行排序的简单函数 [英] Simple function to sort an array of objects

问题描述

我想创建一个(非匿名)函数，该函数按键name 的字母顺序对对象数组进行排序.我只编写直接的 JavaScript，所以框架对我没有任何帮助.

I would like to create a (non-anonymous) function that sorts an array of objects alphabetically by the key name. I only code straight-out JavaScript so frameworks don't help me in the least.

var people = [
    {'name': 'a75', 'item1': false, 'item2': false},
    {'name': 'z32', 'item1': true,  'item2': false},
    {'name': 'e77', 'item1': false, 'item2': false}
];

推荐答案

这个怎么样?

var people = [
{
    name: 'a75',
    item1: false,
    item2: false
},
{
    name: 'z32',
    item1: true,
    item2: false
},
{
    name: 'e77',
    item1: false,
    item2: false
}];

function sort_by_key(array, key)
{
 return array.sort(function(a, b)
 {
  var x = a[key]; var y = b[key];
  return ((x < y) ? -1 : ((x > y) ? 1 : 0));
 });
}

people = sort_by_key(people, 'name');

这允许您指定要用来对数组进行排序的键，这样您就不受限于硬编码的名称排序.它将对所有共享用作它们的键的属性的任何对象数组进行排序.我相信这就是您要找的?

This allows you to specify the key by which you want to sort the array so that you are not limited to a hard-coded name sort. It will work to sort any array of objects that all share the property which is used as they key. I believe that is what you were looking for?
