자바스크립트 배열 정렬()

배열 정렬:

const fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits.sort();

정렬한 다음 순서를 반대로 합니다.

const fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits.sort();
fruits.reverse();

정의 및 사용

sort()배열의 요소를 정렬합니다 .

원래 sort()배열을 덮어씁니다.

sort()요소를 알파벳 및 오름차순으로 문자열로 정렬합니다 .

정렬 비교 기능

알파벳순 정렬은 문자열에 대해 잘 작동합니다("Apple"가 "Banana" 앞에 옴).

그러나 숫자를 정렬하면 잘못된 결과가 생성될 수 있습니다.

"2"가 "1"보다 크므로 "25"가 "100"보다 큽니다.

"비교 기능"을 제공하여 이 문제를 해결할 수 있습니다(아래 예 참조).


통사론

array.sort(compareFunction)

매개변수

Parameter Description
compareFunction Optional.
A function that defines a sort order. The function should return a negative, zero, or positive value, depending on the arguments:
  • function(a, b){return a-b}

When sort() compares two values, it sends the values to the compare function, and sorts the values according to the returned (negative, zero, positive) value.

Example:

The sort function will sort 40 as a value lower than 100.

When comparing 40 and 100, sort() calls the function(40,100).

The function calculates 40-100, and returns -60 (a negative value).

더 많은 예

오름차순으로 숫자 정렬:

const points = [40, 100, 1, 5, 25, 10];
points.sort(function(a, b){return a-b});

내림차순으로 숫자 정렬:

const points = [40, 100, 1, 5, 25, 10];
points.sort(function(a, b){return b-a});

가장 낮은 값 찾기:

const points = [40, 100, 1, 5, 25, 10];

// Sort the numbers in ascending order
points.sort(function(a, b){return a-b});

let lowest = points[0];

가장 높은 값 찾기:

const points = [40, 100, 1, 5, 25, 10];

// Sort the numbers in descending order:
points.sort(function(a, b){return b-a});

let lowest = points[0];

가장 높은 값 찾기:

const points = [40, 100, 1, 5, 25, 10];

// Sort the numbers in ascending order:
points.sort(function(a, b){return a-b});

let highest = points[points.length-1];

브라우저 지원

sort() ECMAScript1(ES1) 기능입니다.

ES1(JavaScript 1997)은 모든 브라우저에서 완벽하게 지원됩니다.
