Bagaimana Anda mengurutkan array pada beberapa kolom?

119

Saya memiliki array multidimensi. Larik utama adalah larik

[publicationID][publication_name][ownderID][owner_name]

Apa yang saya coba lakukan adalah mengurutkan array berdasarkan owner_namedan kemudian oleh publication_name. Saya tahu di JavaScript yang Anda miliki Array.sort(), di mana Anda dapat menempatkan fungsi khusus, dalam kasus saya, saya punya:

function mysortfunction(a, b) {
    var x = a[3].toLowerCase();
    var y = b[3].toLowerCase();

    return ((x < y) ? -1 : ((x > y) ? 1 : 0));
}

Ini bagus untuk hanya menyortir pada kolom satu, yaitu OWNER_NAME, tapi bagaimana saya memodifikasi untuk mengurutkan owner_name, maka publication_name?

Jika nama pemilik berbeda, urutkan menurut mereka. Jika tidak, gunakan nama publikasi untuk tiebreaker.

function mysortfunction(a, b) {

  var o1 = a[3].toLowerCase();
  var o2 = b[3].toLowerCase();

  var p1 = a[1].toLowerCase();
  var p2 = b[1].toLowerCase();

  if (o1 < o2) return -1;
  if (o1 > o2) return 1;
  if (p1 < p2) return -1;
  if (p1 > p2) return 1;
  return 0;

@dcp Saya tidak mengerti bagaimana itu juga bisa mengurutkan atribut kedua. Kecuali Anda mengulangnya sebanyak jumlah kolom yang dipilih .. Apakah saya benar? misalnya[[A, 10], [J, 15], [A, 5], [J, 5]] => [[A, 10], [A, 5], [J, 15], [J, 5]]

@ user26409021 - Tidak, itu tidak benar. Itu akan berakhir menjadi [[A, 5], [A, 10], [J, 5], [J, 15]]. Ini mengurutkan berdasarkan atribut pertama terlebih dahulu, dan jika keduanya sama, maka itu diurutkan berdasarkan atribut kedua. Jadi dalam contoh Anda, A akan muncul sebelum J. Dalam kasus di mana A sama untuk dua elemen, maka A akan menggunakan atribut kedua. Jadi Untuk [A, 10], [A, 5], 5 muncul sebelum 10 sehingga akan berakhir dengan [A, 5], [A, 10] untuk pemesanan. Hal yang mungkin Anda lewatkan adalah mysortfunction dipanggil beberapa kali saat Anda menggunakan Array.sort hingga penyortiran selesai.
— dcp
3
@ user26409021 - Perulangan tidak diperlukan dalam fungsi mysortfunction, karena Array.sort akan memanggil fungsi sesuai kebutuhan hingga Array diurutkan dengan benar. Satu-satunya fungsi mysort adalah menentukan apakah argumen a dan b sama, apakah a lebih kecil dari b, atau apakah a lebih besar dari b. Kami tidak membutuhkan putaran untuk membuat tekad itu. Semoga membantu.

Saya pikir yang Anda cari adalah thenBy.js: https://github.com/Teun/thenBy.js

Ini memungkinkan Anda untuk menggunakan Array.sort standar, tetapi dengan firstBy().thenBy().thenBy()gaya.

Contohnya bisa dilihat disini .

Hati-hati dengan kinerja pada set data besar. Setiap kali thenBydipanggil, semua item array diulangi lagi.
— Ray Shan

Jelas bukan itu masalahnya. Ketika Anda memanggil thenBy (), itu membangun fungsi baru yang merangkum yang sebelumnya. Pada waktu penyortiran, javascript tidak akan secara ketat "mengulang" item, tetapi akan memanggil fungsi yang Anda lewati berkali-kali. Jumlah panggilan tidak akan berubah dengan menggunakan thenBy. Untuk beberapa pertimbangan kinerja, baca: github.com/Teun/thenBy.js#a-word-on-performance
— Teun D
2
Saya mengerti, saya salah, terima kasih telah memikirkan kinerja. Mungkin menambahkan catatan tentang pertimbangan memori membuat closure dengan fungsi baru?
— Ray Shan
Bagaimana cara menggunakan ini untuk beberapa dinamika? atau di loop?
— Hemil Patel
@Harry Jika Anda tidak dapat membuatnya berfungsi, kirimkan masalah dengan contoh yang tidak dapat Anda urutkan, sehingga orang lain juga dapat belajar. Senang bisa membantu Anda. github.com/Teun/thenBy.js/issues

Cara yang baik untuk mengurutkan pada banyak bidang yang merupakan string adalah dengan menggunakan toLocaleCompare dan operator boolean ||.

Sesuatu seperti:

// Sorting record releases by name and then by title.
releases.sort((oldRelease, newRelease) => {
  const compareName = oldRelease.name.localeCompare(newRelease.name);
  const compareTitle = oldRelease.title.localeCompare(newRelease.title);

  return compareName || compareTitle;
})

Jika Anda ingin mengurutkan pada lebih banyak bidang, Anda cukup mengikatnya dari pernyataan return dengan lebih banyak operator boolean.

— tbranyen.dll

Faktanya, Anda dapat merapikannya dengan.reduce()
— ekkis
namun, .localCompare()mengembalikan -1, 0, 1 jadi menurut saya solusi Anda tidak akan berfungsi sebagai || baik untuk boolean
— ekkis
10
@ekkis, baik 1 dan -1 "benar", jadi ini adalah solusi yang sangat elegan. Saya baru saja melakukan ini: sortItems = (a, b) => (a.distance - b.distance) || (a.name - b.name); dan ini bekerja seperti pesona untuk kebutuhan saya yang tidak pilih-pilih.
— pertama

@bst cara Anda lebih baik, karena tidak mengevaluasi (a.name - b.name)kecuali diperlukan. Membuat variabel terlebih dahulu melakukan pekerjaan tambahan meskipun tidak diperlukan.
— andi
Itu benar, ini melakukan lebih banyak pekerjaan daripada yang diperlukan, tetapi saya hanya akan mengubahnya di area kritis. Untuk kode yang mengurutkan sejumlah data, kejelasan kode mengalahkan kinerja.

Menemukan kebutuhan untuk melakukan pengurutan array objek asc dan desc gaya SQL dengan kunci.

Solusi kennebec di atas membantu saya mencapai ini:

Array.prototype.keySort = function(keys) {

keys = keys || {};

// via
// /programming/5223/length-of-javascript-object-ie-associative-array
var obLen = function(obj) {
    var size = 0, key;
    for (key in obj) {
        if (obj.hasOwnProperty(key))
            size++;
    }
    return size;
};

// avoiding using Object.keys because I guess did it have IE8 issues?
// else var obIx = function(obj, ix){ return Object.keys(obj)[ix]; } or
// whatever
var obIx = function(obj, ix) {
    var size = 0, key;
    for (key in obj) {
        if (obj.hasOwnProperty(key)) {
            if (size == ix)
                return key;
            size++;
        }
    }
    return false;
};

var keySort = function(a, b, d) {
    d = d !== null ? d : 1;
    // a = a.toLowerCase(); // this breaks numbers
    // b = b.toLowerCase();
    if (a == b)
        return 0;
    return a > b ? 1 * d : -1 * d;
};

var KL = obLen(keys);

if (!KL)
    return this.sort(keySort);

for ( var k in keys) {
    // asc unless desc or skip
    keys[k] = 
            keys[k] == 'desc' || keys[k] == -1  ? -1 
          : (keys[k] == 'skip' || keys[k] === 0 ? 0 
          : 1);
}

this.sort(function(a, b) {
    var sorted = 0, ix = 0;

    while (sorted === 0 && ix < KL) {
        var k = obIx(keys, ix);
        if (k) {
            var dir = keys[k];
            sorted = keySort(a[k], b[k], dir);
            ix++;
        }
    }
    return sorted;
});
return this;
};

penggunaan sampel:

var obja = [
  {USER:"bob",  SCORE:2000, TIME:32,    AGE:16, COUNTRY:"US"},
  {USER:"jane", SCORE:4000, TIME:35,    AGE:16, COUNTRY:"DE"},
  {USER:"tim",  SCORE:1000, TIME:30,    AGE:17, COUNTRY:"UK"},
  {USER:"mary", SCORE:1500, TIME:31,    AGE:19, COUNTRY:"PL"},
  {USER:"joe",  SCORE:2500, TIME:33,    AGE:18, COUNTRY:"US"},
  {USER:"sally",    SCORE:2000, TIME:30,    AGE:16, COUNTRY:"CA"},
  {USER:"yuri", SCORE:3000, TIME:34,    AGE:19, COUNTRY:"RU"},
  {USER:"anita",    SCORE:2500, TIME:32,    AGE:17, COUNTRY:"LV"},
  {USER:"mark", SCORE:2000, TIME:30,    AGE:18, COUNTRY:"DE"},
  {USER:"amy",  SCORE:1500, TIME:29,    AGE:19, COUNTRY:"UK"}
];

var sorto = {
  SCORE:"desc",TIME:"asc", AGE:"asc"
};

obja.keySort(sorto);

menghasilkan yang berikut:

 0: {     USER: jane;     SCORE: 4000;    TIME: 35;       AGE: 16;    COUNTRY: DE;   }
 1: {     USER: yuri;     SCORE: 3000;    TIME: 34;       AGE: 19;    COUNTRY: RU;   }
 2: {     USER: anita;    SCORE: 2500;    TIME: 32;       AGE: 17;    COUNTRY: LV;   }
 3: {     USER: joe;      SCORE: 2500;    TIME: 33;       AGE: 18;    COUNTRY: US;   }
 4: {     USER: sally;    SCORE: 2000;    TIME: 30;       AGE: 16;    COUNTRY: CA;   }
 5: {     USER: mark;     SCORE: 2000;    TIME: 30;       AGE: 18;    COUNTRY: DE;   }
 6: {     USER: bob;      SCORE: 2000;    TIME: 32;       AGE: 16;    COUNTRY: US;   }
 7: {     USER: amy;      SCORE: 1500;    TIME: 29;       AGE: 19;    COUNTRY: UK;   }

Ini berguna untuk jenis alfa dari semua ukuran. Berikan indeks yang ingin Anda sortir, secara berurutan, sebagai argumen.

Array.prototype.deepSortAlpha= function(){
    var itm, L=arguments.length, order=arguments;

    var alphaSort= function(a, b){
        a= a.toLowerCase();
        b= b.toLowerCase();
        if(a== b) return 0;
        return a> b? 1:-1;
    }
    if(!L) return this.sort(alphaSort);

    this.sort(function(a, b){
        var tem= 0,  indx=0;
        while(tem==0 && indx<L){
            itm=order[indx];
            tem= alphaSort(a[itm], b[itm]); 
            indx+=1;        
        }
        return tem;
    });
    return this;
}

var arr= [[ "Nilesh","Karmshil"], ["Pranjal","Deka"], ["Susants","Ghosh"],
["Shiv","Shankar"], ["Javid","Ghosh"], ["Shaher","Banu"], ["Javid","Rashid"]];

arr.deepSortAlpha(1,0);

Saya sarankan untuk menggunakan pembanding dan rantai bawaan yang diinginkan dengan urutan logis atau ||.

function customSort(a, b) {
    return a[3].localeCompare(b[3]) || a[1].localeCompare(b[1]);
}

Contoh kerja:

var array = [
    [0, 'Aluminium', 0, 'Francis'],
    [1, 'Argon', 1, 'Ada'],
    [2, 'Brom', 2, 'John'],
    [3, 'Cadmium', 3, 'Marie'],
    [4, 'Fluor', 3, 'Marie'],
    [5, 'Gold', 1, 'Ada'],
    [6, 'Kupfer', 4, 'Ines'],
    [7, 'Krypton', 4, 'Joe'],
    [8, 'Sauerstoff', 3, 'Marie'],
    [9, 'Zink', 5, 'Max']
];

array.sort(function (a, b) {
    return a[3].localeCompare(b[3]) || a[1].localeCompare(b[1]);
});

document.write('<pre>');
array.forEach(function (a) {
    document.write(JSON.stringify(a) + '<br>');
});

Anda dapat menggabungkan 2 variabel menjadi kunci sortir dan menggunakannya untuk perbandingan Anda.

list.sort(function(a,b){
   var aCat = a.var1 + a.var2;
   var bCat = b.var1 + b.var2;
   return (aCat > bCat ? 1 : aCat < bCat ? -1 : 0);
});

@GustavoRodrigues mungkin karena terlalu rapuh. Ini akan gagal untuk mengurutkan dalam mode yang diharapkan pada tombol masukan tertentu karena hanya menyatukan dua bagian tanpa pembatas atau pembedaan lainnya. Pertimbangkan jika var1 dan var2 untuk item X adalah "foo" dan "baz", sedangkan var1 untuk item Y adalah "foobar". Ketika diurutkan, X harus didahulukan tetapi dalam hal ini akan menjadi yang kedua. Jawaban ini dapat diperbaiki tetapi seperti yang dinyatakan itu tidak aman.

Saya menemukan multisotr . Ini adalah pustaka sederhana, kuat, dan kecil untuk beberapa penyortiran. Saya perlu mengurutkan berbagai objek dengan kriteria pengurutan dinamika:

const criteria = ['name', 'speciality']
const data = [
  { name: 'Mike', speciality: 'JS', age: 22 },
  { name: 'Tom', speciality: 'Java', age: 30 },
  { name: 'Mike', speciality: 'PHP', age: 40 },
  { name: 'Abby', speciality: 'Design', age: 20 },
]

const sorted = multisort(data, criteria)

Saya sedang bekerja ng-griddan perlu untuk menyortir beberapa kolom pada array catatan yang dikembalikan dari API, jadi saya datang dengan fungsi multi-sortir yang bagus dan dinamis ini.

Pertama-tama, ng-gridaktifkan "peristiwa" untuk "ngGridSorted" dan meneruskan struktur ini kembali, yang menjelaskan jenisnya:

sortData = {
    columns:    DOM Element,
    directions: [], //Array of string values desc or asc. Each index relating to the same index of fields
    fields:     [], //Array of string values
};

Jadi saya membangun sebuah fungsi yang secara dinamis akan menghasilkan fungsi sortir berdasarkan sortDataseperti yang ditunjukkan di atas ( Jangan takut dengan scroll bar! Panjangnya hanya sekitar 50 baris! Juga, saya minta maaf tentang slop. Ini mencegah horizontal scrollbar! ):

function SortingFunction(sortData)
{
    this.sortData = sortData;

    this.sort = function(a, b)
    {
        var retval = 0;

        if(this.sortData.fields.length)
        {
            var i = 0;

            /*
                Determine if there is a column that both entities (a and b)
                have that are not exactly equal. The first one that we find
                will be the column we sort on. If a valid column is not
                located, then we will return 0 (equal).
            */
            while(  (   !a.hasOwnProperty(this.sortData.fields[i]) 
                    ||  !b.hasOwnProperty(this.sortData.fields[i]) 
                    ||  (a.hasOwnProperty(this.sortData.fields[i]) 
                        && b.hasOwnProperty(this.sortData.fields[i]) 
                        && a[this.sortData.fields[i]] === b[this.sortData.fields[i]])
                    ) && i < this.sortData.fields.length){
                i++;
            }

            if(i < this.sortData.fields.length)
            {
                /*
                    A valid column was located for both entities
                    in the SortData. Now perform the sort.
                */
                if(this.sortData.directions 
                && i < this.sortData.directions.length 
                && this.sortData.directions[i] === 'desc')
                {
                    if(a[this.sortData.fields[i]] > b[this.sortData.fields[i]])
                        retval = -1;
                    else if(a[this.sortData.fields[i]] < b[this.sortData.fields[i]])
                        retval = 1;
                }
                else
                {
                    if(a[this.sortData.fields[i]] < b[this.sortData.fields[i]])
                        retval = -1;
                    else if(a[this.sortData.fields[i]] > b[this.sortData.fields[i]])
                        retval = 1;
                }
            }
        }

        return retval;
    }.bind(this);
}

Saya kemudian mengurutkan hasil API saya ( results) seperti ini:

results.sort(new SortingFunction(sortData).sort);

Saya harap orang lain menikmati solusi ini seperti saya! Terima kasih!

Metode Penambahan String

Anda dapat mengurutkan berdasarkan beberapa nilai hanya dengan menambahkan nilai ke dalam string dan membandingkan string. Akan sangat membantu jika menambahkan karakter kunci terpisah untuk mencegah limpasan dari satu kunci ke kunci berikutnya.

Contoh

const arr = [ 
    { a: 1, b: 'a', c: 3 },
    { a: 2, b: 'a', c: 5 },
    { a: 1, b: 'b', c: 4 },
    { a: 2, b: 'a', c: 4 }
]


function sortBy (arr, keys, splitKeyChar='~') {
    return arr.sort((i1,i2) => {
        const sortStr1 = keys.reduce((str, key) => str + splitKeyChar+i1[key], '')
        const sortStr2 = keys.reduce((str, key) => str + splitKeyChar+i2[key], '')
        return sortStr1.localeCompare(sortStr2)
    })
}

Saya mengalami masalah serupa saat menampilkan blok kumpulan memori dari output beberapa komposisi h-fungsi DOM virtual. Pada dasarnya saya menghadapi masalah yang sama seperti menyortir data multi-kriteria seperti hasil skor dari pemain di seluruh dunia.

Saya perhatikan bahwa pengurutan multi-kriteria adalah:

- sort by the first column
- if equal, sort by the second
- if equal, sort by the third
-  etc... nesting and nesting if-else

Dan jika Anda tidak peduli, Anda bisa gagal dengan cepat di neraka bersarang jika-lagi ... seperti janji neraka ...

Bagaimana jika kita menulis fungsi "predikat" untuk memutuskan bagian mana dari alternatif yang digunakan? Predikatnya sederhana:

// useful for chaining test
const decide = (test, other) => test === 0 ? other : test

Sekarang setelah menulis pengujian klasifikasi Anda (byCountrySize, byAge, byGameType, byScore, byLevel ...) apa pun yang dibutuhkan, Anda dapat memberi bobot pada pengujian Anda (1 = asc, -1 = desc, 0 = nonaktifkan), letakkan dalam array , dan terapkan fungsi pengurangan 'putuskan' seperti ini:

const multisort = (s1, s2) => {
  const bcs = -1 * byCountrySize(s1, s2) // -1 = desc 
  const ba =  1 *byAge(s1, s2)
  const bgt = 0 * byGameType(s1, s2) // 0 = doesn't matter
  const bs = 1 * byScore(s1, s2)
  const bl = -1 * byLevel(s1, s2) // -1 = desc

  // ... other weights and criterias

  // array order matters !
  return [bcs, ba, bgt, bs, bl].reduce((acc, val) => decide(val, acc), 0)
}

// invoke [].sort with custom sort...
scores.sort(multisort)

Dan voila! Terserah Anda untuk menentukan kriteria / bobot / pesanan Anda sendiri ... tetapi Anda mengerti. Semoga ini membantu !

EDIT: * pastikan bahwa ada total urutan penyortiran pada setiap kolom * perhatikan tidak adanya ketergantungan antar urutan kolom, dan tidak ada ketergantungan melingkar

jika, tidak, penyortiran bisa menjadi tidak stabil!

Saya baru saja menerbitkan ke npm perpustakaan mikro yang disebut sort-helper ( sumber di github ) . Idenya adalah mengimpor helper byuntuk membuat fungsi perbandingan untuk sortmetode array melalui sintaks items.sort(by(column, ...otherColumns)), dengan beberapa cara untuk mengekspresikan kolom yang akan diurutkan berdasarkan:

  • Dengan kunci : persons.sort(by('lastName', 'firstName')),
  • Oleh pemilih : dates.sort(by(x => x.toISOString())),
  • Dalam urutan menurun : [3, 2, 4, 1].sort(by(desc(n => n)))→ [3, 2, 1, 0],
  • Mengabaikan kasus : ['B', 'D', 'c', 'a'].sort(by(ignoreCase(x => x))).join('')→ 'aBcD'.

Ini mirip dengan nice thenBy disebutkan dalam jawaban ini tetapi dengan perbedaan berikut yang mungkin lebih sesuai dengan selera beberapa:

  • Pendekatan yang lebih fungsional daripada berorientasi objek (lihat thenByAPI fasih) ,
  • Sebuah sintaks sedikit lebih pendek dan masih banyak yang bisa dibaca, natural hampir seperti SQL.
  • Diimplementasikan sepenuhnya dalam TypeScript, untuk mendapatkan keuntungan dari keamanan tipe dan ekspresi tipe.
