JavaScript nuevo Fecha Ordinal(st, nd, rd, th)

date ordinal-indicator

Question

Si es posible, sin las bibliotecas de JavaScript o muchos códigos torpes, estoy buscando la forma más sencilla de formatear una fecha dentro de dos semanas en el siguiente formato:

13th March 2013

El código que estoy usando es:

var newdate = new Date(+new Date + 12096e5);
document.body.innerHTML = newdate;

que devuelve la fecha y la hora dentro de dos semanas, pero así: Mié 27 de marzo 2013 21:50:29 GMT + 0000 (Hora estándar de GMT)

Aquí está el código en jsFiddle .

¡Cualquier ayuda sería apreciada!

Answer 1

Aquí hay un liner inspirado en las otras respuestas. Se prueba y tomará 0 y números negativos.

function getOrdinalNum(n) {
return n + (n > 0 ? [''th'', ''st'', ''nd'', ''rd''][(n > 3 && n < 21) || n % 10 > 3 ? 0 : n % 10] : '''');
}

Answer 2

Aquí hay una solución fácil:

var date = today.getDate() + (today.getDate() % 10 == 1 && today.getDate() != 11 ? + ''st'': (today.getDate() % 10 == 2 && today.getDate() != 12 ? + ''nd'':
(today.getDate() % 10 == 3 && today.getDate() != 13 ? + ''rd'':''th'')));

Answer 3

Aquí:

Demo en vivo

var fortnightAway = new Date(+new Date + 12096e5),
date = fortnightAway.getDate(),
month = "January,February,March,April,May,June,July,August,September,October,November,December"
.split(",")[fortnightAway.getMonth()];
function nth(d) {
if(d>3 && d<21) return ''th''; // thanks kennebec
switch (d % 10) {
case 1: return "st";
case 2: return "nd";
case 3: return "rd";
default: return "th";
}
}
document.body.innerHTML = date+nth(date) +" "
+month+" "+fortnightAway.getFullYear();

Answer 4

Como muchos han mencionado, aquí hay otra respuesta.

Esto se basa directamente en la respuesta de @kennebec , que encontré la forma más sencilla de obtener esta fecha Ordinal generada para una fecha dada de JavaScript :

He creado dos prototype function siguiente manera:

Date.prototype.getDateWithDateOrdinal = function() {
var d = this.getDate(); // from here on I''ve used Kennebec''s answer, but improved it.
if(d>3 && d<21) return d+''th'';
switch (d % 10) {
case 1: return d+"st";
case 2: return d+"nd";
case 3: return d+"rd";
default: return d+"th";
}
};
Date.prototype.getMonthName = function(shorten) {
var monthsNames = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];
var monthIndex = this.getMonth();
var tempIndex = -1;
if (monthIndex == 0){ tempIndex = 0 };
if (monthIndex == 1){ tempIndex = 1 };
if (monthIndex == 2){ tempIndex = 2 };
if (monthIndex == 3){ tempIndex = 3 };
if (monthIndex == 4){ tempIndex = 4 };
if (monthIndex == 5){ tempIndex = 5 };
if (monthIndex == 6){ tempIndex = 6 };
if (monthIndex == 7){ tempIndex = 7 };
if (monthIndex == 8){ tempIndex = 8 };
if (monthIndex == 9){ tempIndex = 9 };
if (monthIndex == 10){ tempIndex = 10 };
if (monthIndex == 11){ tempIndex = 11 };
if (tempIndex > -1) {
this.monthName = (shorten) ? monthsNames[tempIndex].substring(0, 3) : monthsNames[tempIndex];
} else {
this.monthName = "";
}
return this.monthName;
};

Nota: simplemente incluya las funciones de prototype anteriores en su JS Script y utilícelas como se describe a continuación.

Y siempre que haya una fecha de JS , necesito generar la fecha con la fecha ordinal. Utilizo ese método de prototipo como se indica a continuación en esa fecha de JS :

var myDate = new Date();
// You may have to check your JS Console in the web browser to see the following
console.log("date with date ordinal: "+myDate.getDateWithDateOrdinal()+" "+myDate.getMonthName()+" "+myDate.getFullYear());
// or I will update the Div. using jQuery
$(''#date'').html("date with date ordinal: "+myDate.getDateWithDateOrdinal()+" "+myDate.getMonthName()+" "+myDate.getFullYear());

E imprimirá la fecha con la fecha ordinal como se muestra en la siguiente demostración en vivo :

 Date.prototype.getMonthName = function(shorten) {
var monthsNames = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];
var monthIndex = this.getMonth();
var tempIndex = -1;
if (monthIndex == 0){ tempIndex = 0 };
if (monthIndex == 1){ tempIndex = 1 };
if (monthIndex == 2){ tempIndex = 2 };
if (monthIndex == 3){ tempIndex = 3 };
if (monthIndex == 4){ tempIndex = 4 };
if (monthIndex == 5){ tempIndex = 5 };
if (monthIndex == 6){ tempIndex = 6 };
if (monthIndex == 7){ tempIndex = 7 };
if (monthIndex == 8){ tempIndex = 8 };
if (monthIndex == 9){ tempIndex = 9 };
if (monthIndex == 10){ tempIndex = 10 };
if (monthIndex == 11){ tempIndex = 11 };
if (tempIndex > -1) {
this.monthName = (shorten) ? monthsNames[tempIndex].substring(0, 3) : monthsNames[tempIndex];
} else {
this.monthName = "";
}
return this.monthName;
};
Date.prototype.getDateWithDateOrdinal = function() {
var d = this.getDate(); // from here on I''ve used Kennebec''s answer, but improved it.
if(d>3 && d<21) return d+''th'';
switch (d % 10) {
case 1: return d+"st";
case 2: return d+"nd";
case 3: return d+"rd";
default: return d+"th";
}
};
var myDate = new Date();
// You may have to check your JS Console in the web browser to see the following
console.log("date with date ordinal: "+myDate.getDateWithDateOrdinal()+" "+myDate.getMonthName()+" "+myDate.getFullYear());
// or I will update the Div. using jQuery
$(''#date'').html("date with date ordinal: "+myDate.getDateWithDateOrdinal()+" "+myDate.getMonthName()+" "+myDate.getFullYear());

Answer 5

Fuertemente inspirado en @ user2309185 ''s.

const ordinal = (d) => {
return d + ([''st'', ''nd'', ''rd''][d % 10 - 1] || ''th'')
}

Answer 6

Implementación funcional super simple:

const ordinal = (d) => {
const nth = { ''1'': ''st'', ''2'': ''nd'', ''3'': ''rd'' }
return `${d}${nth[d] || ''th''}`
}
const monthNames = [''January'',''February'',''March'',''April'',''May'',''June'',''July'',''August'',''September'',''October'',''November'',''December'']
const dateString = (date) => `${ordinal(date.getDate())} ${monthNames[date.getMonth()]} ${date.getFullYear()}`
// Use like this:
dateString(new Date()) // 18th July 2016

Answer 7

Llego un poco tarde a la fiesta, pero esto debería funcionar:

function ordinal(number) {
number = Number(number)
if(!number || (Math.round(number) !== number)) {
return number
}
var signal = (number < 20) ? number : Number(('''' + number).slice(-1))
switch(signal) {
case 1:
return number + ''st''
case 2:
return number + ''nd''
case 3:
return number + ''rd''
default:
return number + ''th''
}
}
function specialFormat(date) {
// add two weeks
date = new Date(+date + 12096e5)
var months = [
''January''
, ''February''
, ''March''
, ''April''
, ''May''
, ''June''
, ''July''
, ''August''
, ''September''
, ''October''
, ''November''
, ''December''
]
var formatted = ordinal(date.getDate())
formatted += '' '' + months[date.getMonth()]
return formatted + '' '' + date.getFullYear()
}
document.body.innerHTML = specialFormat(new Date())

Answer 8

Muchas respuestas de formateo, así que trabajaré en la novena parte de cualquier entero

Number.prototype.nth= function(){
if(this%1) return this;
var s= this%100;
if(s>3 && s<21) return this+''th'';
switch(s%10){
case 1: return this+''st'';
case 2: return this+''nd'';
case 3: return this+''rd'';
default: return this+''th'';
}
}

Answer 9

Muchas respuestas, aquí hay otra:

function addOrd(n) {
var ords = [,''st'',''nd'',''rd''];
var ord, m = n%100;
return n + ((m > 10 && m < 14)? ''th'' : ords[m%10] || ''th'');
}
// Return date string two weeks from now (14 days) in
// format 13th March 2013
function formatDatePlusTwoWeeks(d) {
var months = [''January'',''February'',''March'',''April'',''May'',''June'',
''July'',''August'',''September'',''October'',''November'',''December''];
// Copy date object so don''t modify original
var e = new Date(d);
// Add two weeks (14 days)
e.setDate(e.getDate() + 14);
return addOrd(e.getDate()) + '' '' + months[e.getMonth()] + '' '' + e.getFullYear();
}
alert(formatDatePlusTwoWeeks(new Date(2013,2,13))); // 27th March 2013

Answer 10

También lo estaba haciendo para las fechas, pero como el día del mes solo puede estar entre el 1 y el 31, terminé con una solución simplificada.

function dateOrdinal(dom) {
if (dom == 31 || dom == 21 || dom == 1) return dom + "st";
else if (dom == 22 || dom == 2) return dom + "nd";
else if (dom == 23 || dom == 3) return dom + "rd";
else return dom + "th";
};

o versión compacta utilizando operadores condicionales.

function dateOrdinal(d) {
return d+(31==d||21==d||1==d?"st":22==d||2==d?"nd":23==d||3==d?"rd":"th")
};

Answer 11

Una solución corta y compacta:

function format(date, tmp){
return [
(tmp = date.getDate()) +
([, ''st'', ''nd'', ''rd''][/1?.$/.exec(tmp)] || ''th''),
[ ''January'', ''February'', ''March'', ''April'',
''May'', ''June'', ''July'', ''August'',
''September'', ''October'', ''November'', ''December''
][date.getMonth()],
date.getFullYear()
].join('' '')
}
// 14 days from today
console.log(''14 days from today: '' +
format(new Date(+new Date + 14 * 864e5)));
// test formatting for all dates within a month from today
var day = 864e5, today = +new Date;
for(var i = 0; i < 32; i++) {
console.log(''Today + '' + i + '': '' + format(new Date(today + i * day)))
}

(El enfoque compacto basado en expresiones regulares para obtener el sufijo ordinal appears several places la web, se desconoce la fuente original)
