Sortuje tablice czegokolwiek !
Moja osobista ulubiona forma tej funkcji pozwala na określenie parametru Rosnąco lub Malejąco:
function intArraySort(c, a) {
function d(a, b) { return b - a; }
"string" == typeof a && a.toLowerCase();
switch (a) {
default: return c.sort(function(a, b) { return a - b; });
case 1:
case "d":
case "dc":
case "desc":
return c.sort(d)
}
};
Użycie tak proste jak:
var ara = function getArray() {
var a = Math.floor(Math.random()*50)+1, b = [];
for (i=0;i<=a;i++) b.push(Math.floor(Math.random()*50)+1);
return b;
}();
// Ascending
intArraySort(ara);
console.log(ara);
// Descending
intArraySort(ara, 1);
console.log(ara);
// Ascending
intArraySort(ara, 'a');
console.log(ara);
// Descending
intArraySort(ara, 'dc');
console.log(ara);
// Ascending
intArraySort(ara, 'asc');
console.log(ara);
Lub przykładowy fragment kodu tutaj!
function intArraySort(c, a) {
function d(a, b) { return b - a }
"string" == typeof a && a.toLowerCase();
switch (a) {
default: return c.sort(function(a, b) { return a - b });
case 1:
case "d":
case "dc":
case "desc":
return c.sort(d)
}
};
function tableExample() {
var d = function() {
var a = Math.floor(50 * Math.random()) + 1,
b = [];
for (i = 0; i <= a; i++) b.push(Math.floor(50 * Math.random()) + 1);
return b
},
a = function(a) {
var b = $("<tr/>"),
c = $("<th/>").prependTo(b);
$("<td/>", {
text: intArraySort(d(), a).join(", ")
}).appendTo(b);
switch (a) {
case 1:
case "d":
case "dc":
case "desc":
c.addClass("desc").text("Descending");
break;
default:
c.addClass("asc").text("Ascending")
}
return b
};
return $("tbody").empty().append(a(), a(1), a(), a(1), a(), a(1), a(), a(1), a(), a(1), a(), a(1))
};
tableExample();
table { border-collapse: collapse; }
th, td { border: 1px solid; padding: .25em .5em; vertical-align: top; }
.asc { color: red; }
.desc { color: blue }

.smartSort („asc” | „desc”)
Teraz baw się jeszcze lepiej dzięki metodzie sortowania, która sortuje tablicę pełną wielu przedmiotów! Obecnie nie obejmuje „asocjacyjnego” (aka, ciągów znaków), ale obejmuje wszystkie wartości! Nie tylko posortuje wiele wartości asc
lub desc
odpowiednio, ale także utrzyma stałą „pozycję” „grup” wartości. Innymi słowy; ints są zawsze pierwsze, potem łańcuchy, potem tablice (tak, robię to wielowymiarowe!), następnie Obiekty (niefiltrowane, element, data), a na koniec niezdefiniowane i zerowe!
"Dlaczego?" ty pytasz. Dlaczego nie!
Teraz występuje w 2 smakach! Pierwsza z nich wymaga nowszych przeglądarek, ponieważ używa Object.defineProperty
metody dodawania metody do Array.protoype
obiektu. Pozwala to na łatwość naturalnego użytkowania, takich jak: myArray.smartSort('a')
. Jeśli chcesz zaimplementować starsze przeglądarki lub po prostu nie lubisz modyfikować obiektów natywnych, przewiń w dół do wersji Tylko metoda .

Użycie jest proste! Najpierw utwórz szaloną tablicę, taką jak:
window.z = [ 'one', undefined, $('<span />'), 'two', null, 2, $('<div />', { id: 'Thing' }), $('<div />'), 4, $('<header />') ];
z.push(new Date('1/01/2011'));
z.push('three');
z.push(undefined);
z.push([ 'one', 'three', 'four' ]);
z.push([ 'one', 'three', 'five' ]);
z.push({ a: 'a', b: 'b' });
z.push({ name: 'bob', value: 'bill' });
z.push(new Date());
z.push({ john: 'jill', jack: 'june' });
z.push([ 'abc', 'def', [ 'abc', 'def', 'cba' ], [ 'cba', 'def', 'bca' ], 'cba' ]);
z.push([ 'cba', 'def', 'bca' ]);
z.push({ a: 'a', b: 'b', c: 'c' });
z.push({ a: 'a', b: 'b', c: 'd' });
Następnie posortuj to!
z.smartSort('asc'); // Ascending
z.smartSort('desc'); // Descending
