Classifica matrizes de qualquer coisa !
Minha forma favorita pessoal dessa função permite um parâmetro para Ascendente ou Descendente:
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)
}
};
Uso tão simples quanto:
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);
Ou exemplo de snippet de código aqui!
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')
Agora divirta-se ainda mais com um método de classificação que classifica uma matriz cheia de vários itens! Atualmente, não abrange "associativo" (também conhecido como chave de cadeia), mas abrange todo tipo de valor! Não apenas classificará os vários valores asc
ou de desc
acordo, mas também manterá constante "posição" de "grupos" de valores. Em outras palavras; ints são sempre os primeiros, depois as strings, as matrizes (sim, estou tornando isso multidimensional!), os objetos (não filtrados, elemento, data) e, finalmente, indefinidos e nulos!
"Por quê?" você pergunta. Por que não!
Agora vem em 2 sabores! O primeiro deles requer navegadores mais recentes, pois ele usa Object.defineProperty
para adicionar o método ao Array.protoype
objeto. Isto permite a facilidade de naturais utilização, tais como: myArray.smartSort('a')
. Se você precisa implementar em navegadores mais antigos ou simplesmente não gosta de modificar objetos nativos, role para baixo até a versão Somente método .

O uso é simples! Primeiro faça uma matriz maluca como:
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' });
Em seguida, basta classificá-lo!
z.smartSort('asc'); // Ascending
z.smartSort('desc'); // Descending
Apenas método
O mesmo que o anterior, exceto apenas como um método simples!
