javascript - 在 JavaScript 中按 3 个不同的标准排序

问题描述

我试图在下面对这个列表进行排序，首先按关系（如果它是订阅者，那么它应该是第一个）然后按活动与非活动。活跃应该在不活跃之前然后每个活跃和不活跃应该按年龄降序排序。所以我有这个数组：

[{status: 'Active', BirthDate: '12/31/1960', Relationship:"Friend"},
{status: 'Active', BirthDate: '12/31/1985', Relationship:"Wife"},
{status: 'Inactive', BirthDate: '12/31/1998', Relationship:"Son"},
{status: 'Inactive', BirthDate: '12/31/1996',Relationship:"Daughter"},
{status: 'Active', BirthDate: '12/31/1995', Relationship:"Daughter"},
{status: 'Active', BirthDate: '12/31/1979', Relationship:"Subscriber"},
{status: 'Inactive', BirthDate: '12/31/1999', Relationship:"Son"}
]

结果应该是：

[{status: 'Active', BirthDate: '12/31/1979', Relationship:"Subscriber"},
{status: 'Active', BirthDate: '12/31/1960', Relationship:"Friend"},
{status: 'Active', BirthDate: '12/31/1985', Relationship:"Wife"},
{status: 'Active', BirthDate: '12/31/1995', Relationship:"Daughter"},
{status: 'Inactive', BirthDate: '12/31/1992', Relationship:"Son"},
{status: 'Inactive', BirthDate: '12/31/1996',Relationship:"Daughter"},
{status: 'Inactive', BirthDate: '12/31/1999', Relationship:"Son"}
]

我在下面尝试了这个，但似乎没有用：

testlist = testlist.sort((a, b) => (a.Relationship === "Subscriber" ) ? -1 :(a.status === "Active") ? -2 : (b.BirthDate - a.BirthDate) ? -3 : 1);

有没有办法通过在 JavaScript 中使用 .sort 方法来做到这一点？

解决方案

使用Array#sort：

const arr = [ {status: 'Active', BirthDate: '12/31/1960', Relationship:"Friend"}, {status: 'Active', BirthDate: '12/31/1985', Relationship:"Wife"}, {status: 'Inactive', BirthDate: '12/31/1998', Relationship:"Son"}, {status: 'Inactive', BirthDate: '12/31/1996',Relationship:"Daughter"}, {status: 'Active', BirthDate: '12/31/1995', Relationship:"Daughter"}, {status: 'Active', BirthDate: '12/31/1979', Relationship:"Subscriber"}, {status: 'Inactive', BirthDate: '12/31/1999', Relationship:"Son"} ];

const sorted = arr.sort(
  (
    { status: statusA, Relationship: relationshipA, BirthDate: birthDateA }, 
    { status: statusB, Relationship: relationshipB, BirthDate: birthDateB }
  ) => {
    const relationship = (relationshipB === 'Subscriber') - (relationshipA === 'Subscriber');
    if(relationship) return relationship;
    const status = (statusB === 'Active') - (statusA === 'Active');
    if(status) return status;
    const birthday = (new Date(birthDateA)).getTime() - (new Date(birthDateB)).getTime();
    return birthday;
  });

console.log(sorted);
