Question

我有以下数组的对象，

{ name: 'Hundred Monkeys',
 address: '52 High Street Glastonbury BA6 9DY' },
{ name: 'J.C Thomas and sons ltd',
 address: 'Thomas Way Glastonbury BA69LU' },
{ name: 'Lady Of The Silver Wheel',
 address: '13 Market Place Glastonbury BA6 9HH' },
{ name: 'The Chalice Well',
 address: '85-89 Chilkwell Street Glastonbury BA6 8DD' },
{ name: 'The Glastonbury Wire Studio',
 address: '48a High Street Glastonbury BA6 9DX' },
{ name: 'The Isle of Avalon Foundation',
 address: 'The Glastonbury Experience, 2-4 High Street, Glastonbury BA6 9DU' },
{ name: 'The King Arthur',
address: '31-33 Benedict Street Glastonbury BA6 9NB' },

我通过

排序

VenueList.sort((a, b) => a.name.localeCompare(b.name));

但所有以'THE'开头的名字都会在T下排序。我可以添加一个条件来忽略第一个单词，如果它是'The'，那我该怎么办呢？感谢。

Answer 1

只需创建新的字符串，而这些字符串中没有您要忽略的数据。

然后比较那些。

VenueList.sort(function (a, b) {
    a = a.name.replace(/^The /, "");
    b = b.name.replace(/^The /, "");
    return a.localeCompare(b);
});

（根据需要调整正则表达式（例如，使其不区分大小写或添加其他单词））

Answer 2

使用decorate-sort-undecorate创建一个元组，其中包含您希望为每个对象排序的字符串。然后使用密钥排序。然后从元组中提取对象。

注意：它似乎有很多不必要的映射，但它节省了在每次比较时提取正确密钥的需要。

const VenueList = [{"name":"Hundred Monkeys","address":"52 High Street Glastonbury BA6 9DY"},{"name":"J.C Thomas and sons ltd","address":"Thomas Way Glastonbury BA69LU"},{"name":"Lady Of The Silver Wheel","address":"13 Market Place Glastonbury BA6 9HH"},{"name":"The Chalice Well","address":"85-89 Chilkwell Street Glastonbury BA6 8DD"},{"name":"The Glastonbury Wire Studio","address":"48a High Street Glastonbury BA6 9DX"},{"name":"The Isle of Avalon Foundation","address":"The Glastonbury Experience, 2-4 High Street, Glastonbury BA6 9DU"},{"name":"The King Arthur","address":"31-33 Benedict Street Glastonbury BA6 9NB"}];

const result = VenueList
  .map((o) => [o.name.replace(/^The\s+/, ''), o]) // create a tuple of ['King Arthur', {"name":"The King Arthur","address": ...}]
  .sort(([a], [b]) => a.localeCompare(b))
  .map(([, o]) => o); // extract the original object {"name":"The King Arthur","address": ...}

console.log(result);

对对象数组进行排序，但忽略名称中的“THE”
