다차원 배열이 있습니다. 기본 배열은
[publicationID][publication_name][ownderID][owner_name] 내가하려는 것은 배열을 정렬 owner_name한 다음 publication_name. 나는 JavaScript에서 당신이 가지고 있다는 것을 알고 있으며 Array.sort(), 여기에 사용자 정의 함수를 넣을 수 있습니다.
function mysortfunction(a, b) {
var x = a[3].toLowerCase();
var y = b[3].toLowerCase();
return ((x < y) ? -1 : ((x > y) ? 1 : 0));
}
이것은 단지, 즉 OWNER_NAME, 하나의 열을 정렬 괜찮지 만, 어떻게 그것을에 정렬 수정합니까 owner_name후 publication_name?
답변:
소유자 이름이 다른 경우이를 기준으로 정렬하십시오. 그렇지 않으면 순위 결정에 게시 이름을 사용하십시오.
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;
}
나는 당신이 찾고있는 것이 thenBy.js라고 생각합니다 : https://github.com/Teun/thenBy.js
표준 Array.sort를 사용할 수 있지만 firstBy().thenBy().thenBy()스타일이 있습니다.
thenBy호출 될 때마다 모든 배열 항목이 다시 반복됩니다.
문자열 인 많은 필드를 정렬하는 좋은 방법은 toLocaleCompare및 부울 연산자 를 사용 하는 것 ||입니다.
다음과 같은 것 :
// 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;
})
더 많은 필드를 정렬하려면 더 많은 부울 연산자를 사용하여 단순히 return 문에서 분리 할 수 있습니다.
.reduce()
.localCompare()-1, 0, 1을 반환하므로 솔루션이 || 부울 좋은입니다
sortItems = (a, b) => (a.distance - b.distance) || (a.name - b.name); 그리고 그것은 나의 까다로운 필요를위한 매력처럼 작동한다.
(a.name - b.name)필요 하지 않는 한 평가 하지 않기 때문에 더 좋습니다 . 변수를 먼저 생성하면 필요하지 않더라도 추가 작업이 수행됩니다.
SQL 스타일 혼합 asc 및 desc 개체 배열을 키별로 정렬해야합니다.
위의 kennebec의 솔루션은 내가 이것을 얻는 데 도움이되었습니다.
Array.prototype.keySort = function(keys) {
keys = keys || {};
// via

var obLen = function(obj) {
var size = 0, 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;

샘플 사용 :

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

obja.keySort(sorto);
다음을 생성합니다.
0: { USER: jane; SCORE: 4000; TIME: 35; AGE: 16; COUNTRY: DE; }

이것은 모든 크기의 알파 종류에 편리합니다. 정렬하려는 인덱스를 순서대로 인수로 전달하십시오.

document.write('<pre>');
array.forEach(function (a) {

});나는 multisotr을 찾았 습니다 . 이것은 다중 정렬을위한 간단하고 강력하며 작은 라이브러리입니다. 역학 정렬 기준으로 개체 배열을 정렬해야했습니다.
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)
console.log(sorted)<script src="https://cdn.rawgit.com/peterkhayes/multisort/master/multisort.js"></script>이 라이브러리는 더 강력 해졌습니다. 그것이 제 경우였습니다. 시도 해봐.
내가 일하던 ng-grid나는이 멋진 동적 다중 정렬 기능을 함께했다 있도록 여러 컬럼에있는 API에서 반환 된 레코드의 배열을 정렬 할 필요가 있었다.
우선, ng-grid"ngGridSorted"에 대한 "이벤트"를 발생시키고이 구조를 다시 전달하여 정렬을 설명합니다.
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
};그래서 sortData위와 같이 동적으로 정렬 함수를 생성하는 함수를 만들었습니다 . 스크롤바! ) :
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);
}그런 다음 API ( results) 의 결과를 다음과 같이 정렬합니다 .
results.sort(new SortingFunction(sortData).sort);다른 사람이 나만큼이 솔루션을 즐기기를 바랍니다! 감사!
이 시도:
t.sort( (a,b)=> a[3].localeCompare(b[3]) || a[1].localeCompare(b[1]) );let t = [ [publicationID, publication_name, ownderID, owner_name ], ... ]소유자의 인덱스가 3이고 발행 이름이 1 인 배열의 데이터를 가정합니다 .
값을 문자열에 추가하고 문자열을 비교하여 여러 값으로 정렬 할 수 있습니다. 한 키에서 다음 키로 유출되는 것을 방지하기 위해 분할 키 문자를 추가하는 것이 유용합니다.

편집 : * 각 열에 총 정렬 순서가 있는지 확인합니다. * 열 순서간에 종속성이없고 순환 종속성이 없음을 인식하십시오.
그렇지 않은 경우 정렬이 불안정 할 수 있습니다!

방금 npm에 sort-helper ( source on github ) 라는 마이크로 라이브러리를 게시했습니다 . 아이디어는 정렬 기준으로 열을 표현하는 여러 가지 방법으로 구문을 통해 배열 메서드에 by대한 비교 함수를 생성 하는 도우미를 가져 오는 것입니다 .sortitems.sort(by(column, ...otherColumns))
persons.sort(by('lastName', 'firstName')),dates.sort(by(x => x.toISOString())),[3, 2, 4, 1].sort(by(desc(n => n)))→ [3, 2, 1, 0],['B', 'D', 'c', 'a'].sort(by(ignoreCase(x => x))).join('')→ 'aBcD'.이 답변 에서 언급 한 nice thenBy 와 유사 하지만 다음과 같은 차이점이 일부의 취향에 더 클 수 있습니다.
thenBy유창한 API 참조 ) ,
[[A, 10], [J, 15], [A, 5], [J, 5]] => [[A, 10], [A, 5], [J, 15], [J, 5]]
