How to sort an array of objects by multiple fields? (41 个回答)

已关闭 7 年前。

我有对象数组:

[{
 user: "userName1",
 roles: [7,4]
},
{
 user: "userName2",
 roles: [0,3]
},
{
 user: "userName4",
 roles: [7,2]
},
{
 user: "userName3",
 roles: [6,5]
}]

我需要按 roles 对该数组进行排序。第一 roles[0]然后roles[1] .

我的结果必须按如下方式排序:

0. userName1
1. userName4
2. userName3
3. userName2

Answer 1

var data = [{ user: "userName1", roles: [7,4] }, { user: "userName2", roles: [0,3] }, { user: "userName4", roles: [7,2] }, { user: "userName3", roles: [6,5] }];

data.sort(function(a,b) {
    if(a.roles[0] == b.roles[0]) return b.roles[1] - a.roles[1];
    return b.roles[0] - a.roles[0];
});


document.write('<pre>'+JSON.stringify(data,0,2) + '</pre>');
