Esiste un equivalente in PHP date() in javascript/jquery?

Question

Sto tentando di calcolare il giorno dell'anno (sia con oggi che con un'altra data).

In PHP è possibile utilizzare la funzione data() e fare quello che voglio ...

C'è qualcosa di simile in JS/jQuery?

Answer 1

Sorpreso nessuno ha postato su moment.js, è molto simile a date.js, ma più leggero (5.5k minified)

http://momentjs.com/

appena fatto un punto di riferimento e lo abbiamo trovato analizza molto più veloce di date.js , ma la formattazione e la manipolazione sono più lente. Per one-liners sarebbe eseguito più velocemente di date.js a causa dell'analisi più rapida.

http://jsperf.com/underscore-date-vs-datejs/7

Alcuni esempi di utilizzo:

// Simulates ajax response 
var data = { someDate: "2023-08-23 11:52:39" } 

// .unix() converts to Unix timestamp: 1692816759 
moment(data.someDate).unix(); 

// Displaying it in a readable format 
// Aug 23, 11:52 AM 
moment("2023-08-23 11:52:39").format('MMM D, hh:mm A'); 

// Now 
moment(); 

// Support for manipulation and chaining 
moment().add('days', 7).subtract('months', 1).hours(15).minutes(0).seconds(0); 

Answer 2

Io uso Datejs.

Answer 3

Se vieni da PHP, potresti goderti questa porta di strftime su JS.

http://hacks.bluesmoon.info/strftime/demo.html

var dateObj = new Date('2011/11/11'); 
var dayOfYear = dateObj.strftime("%j"); 

ho usato un sacco ed è grande. Credo che sia significativamente più leggero di Datejs.

Answer 4

uso il date_to_string() function

Answer 5

Secondo gli autori, phpjs date() è "l'equivalente JavaScript in data PHP". Quindi se è quello che stai cercando, provalo.

Answer 6

se non avete bisogno di supporto completo fuso orario (fusi orari Nord America), ho scritto molto veloce, completamente compatibile phpdate() e la congruenza gmdate() che esattamente emulare il php date e gmdate funzioni. (L'unità test ha un test fuzz che formatta data/ora casuale e confronta con php; Ho eseguito diverse centinaia di timestamp durante il test.) L'ho scritto per nodejs, ma se qualcuno mi aiuta, sarei disposto a portarlo a puro js.

Sono supportati tutti gli specificatori di conversione; nessuna dipendenza esterna.

La settimana ISO e la numerazione anno, il giorno della settimana e l'anno bisestile vengono estratti da dalla data(). Le informazioni sul fuso orario vengono invertite dall'offset UTC reso disponibile da Date().
