additivo prop che ti dà ancora più divertimento!
Ordina le matrici di qualsiasi cosa !
La mia forma preferita personale di questa funzione consente un parametro per Ascendente o Discendente:
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)
}
};
Utilizzo semplice come:
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);
O esempio di frammento di codice qui!
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; }

.smartSort ('asc' | 'desc')
Ora divertiti ancora di più con un metodo di ordinamento che ordina un array pieno di più elementi! Attualmente non copre "associativo" (ovvero chiavi di stringa), ma copre ogni tipo di valore! Non solo ordinerà i valori multipli asc
o di desc
conseguenza, ma manterrà anche la "posizione" costante di "gruppi" di valori. In altre parole; gli interi sono sempre i primi, poi le stringhe, quindi le matrici (sì, lo sto facendo in modo multidimensionale!), quindi gli Oggetti (non filtrato, elemento, data) e infine indefiniti e nulli!
"Perché?" tu chiedi. Perchè no!
Ora arriva in 2 gusti! Il primo dei quali richiede browser più recenti in quanto utilizza Object.defineProperty
per aggiungere il metodo Array.protoype
all'oggetto. Questo permette per la facilità d' naturali uso, come ad esempio: myArray.smartSort('a')
. Se devi implementare per browser meno recenti o semplicemente non ti piace modificare gli oggetti nativi, scorri verso il basso fino alla versione Solo metodo .

L'uso è semplice! Per prima cosa crea un array folle come:
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' });
Quindi ordinalo semplicemente!
z.smartSort('asc'); // Ascending
z.smartSort('desc'); // Descending
Solo metodo
Come il precedente, ad eccezione di un semplice metodo!
