Question

已经看到有关排序javascript对象的问题，但没有看到如何对对象内的对象进行排序。

我在下面有一个包含多个对象的javascript对象（实际上数据要大得多）。如何按照last_name中的值按升序或降序对“数据”内的所有内容进行排序，并输出一个新的已排序的“数据”对象？

{"data":[
    {"DT_RowId":"row_1","first_name":"Tiger","last_name":"Nixon","age":"61"},
   {"DT_RowId":"row_2","first_name":"Garrett","last_name":"Winters","age":"63"},
    {"DT_RowId":"row_3","first_name":"Ashton","last_name":"Cox","age":"66"},
    {"DT_RowId":"row_4","first_name":"Cedric","last_name":"Kelly","age":"22"},
    {"DT_RowId":"row_5","first_name":"Airi","last_name":"Satou","age":"33"}
    ],"options":[],"files":[]}

Answer 1

尝试lodash orderBy

_.orderBy(data.data, ['first_name'],['asc']);

Answer 2

试试这个：

data.data.sort((a, b) => {
  if (a.first_name < b.first_name)
    return -1
  if (a.first_name > b.first_name)
    return 1
  return 0
})

在此工作：https://jsfiddle.net/6hw777kr/

Answer 3

您可以使用下面的Array.prototype.sort： -

o.data.sort(({ last_name: a }, { last_name: b }) => {
    return (a < b) ? -1 : ((a > b) ? 1 : 0);
});

let o = {
  "data": [{
      "DT_RowId": "row_1",
      "first_name": "Tiger",
      "last_name": "Nixon",
      "age": "61"
    },
    {
      "DT_RowId": "row_2",
      "first_name": "Garrett",
      "last_name": "Winters",
      "age": "63"
    },
    {
      "DT_RowId": "row_3",
      "first_name": "Ashton",
      "last_name": "Cox",
      "age": "66"
    },
    {
      "DT_RowId": "row_4",
      "first_name": "Cedric",
      "last_name": "Kelly",
      "age": "22"
    },
    {
      "DT_RowId": "row_5",
      "first_name": "Airi",
      "last_name": "Satou",
      "age": "33"
    }
  ],
  "options": [],
  "files": []
};
o.data.sort(({ last_name: a }, { last_name: b }) => {
    return (a < b) ? -1 : ((a > b) ? 1 : 0);
});
console.log(o);

Answer 4

您可以使用自定义比较器的数组排序方法。将您的比较逻辑放在函数中。这种排序将在适当的位置进行。如果您有庞大的数据集，那么我建议您在服务器上执行此操作以加快处理速度。

代码：

<Your data>.data.sort(function(item1,item2){
if (item1.last_name < item2.last_name)
  return -1;
if ( item1.last_name > item2.last_name)
  return 1;
return 0;
})
