javascript: object对象按属性排序的方法

 1 var res = {
 2     success: true,
 3     result: [
 4         {
 5             id: 1,
 6             name: ‘Jack‘,
 7             age: 21
 8         },
 9         {
10             id: 2,
11             name: ‘Tom‘,
12             age: 23
13         },
14         {
15             id: 3,
16             name: ‘Rose‘,
17             age: 19
18         }
19     ]
20 };
21 
22 var sortBy = function (a, b) {
23 　　if (a.age > b.age) {
24 　　　　return 1;
25 　　} else if (a.age < b.age) {
26 　　　　return -1;
27 　　} else {
28 　　　　return 0;
29 　　}
30 };
31 
32 var res2 = res.result.sort(sortBy);
33 
34 console.log(JSON.stringify(res2));

// 输出结果[{"id":3,"name":"Rose","age":19},{"id":1,"name":"Jack","age":21},{"id":2,"name":"Tom","age":23}]，实现排序。
