I have a problem with the date () function of javascript what I want is to convert from a string to a date but convert the date minus 1 day.
function myFunction() {
var d = new Date('2018-02-28');
var n = d.toString();
document.getElementById("demo").innerHTML = n;
}
what it shows is:
Tue Feb 27 2018 20:00:00 GMT-0400 (Hora estándar oeste, Sudamérica)
I hope you can help me I need that format, thanks
as comments Jorge Marquez is necessary to add something else, although something curious is that it is not necessarily the time with minutes and seconds. It also works by simply adding a space after the day, in your case:
var d = new Date('2018-02-28 '); // Fijese que hay un espacio despues del 28You can also clarify by placing "00:00", until it works by placing a space and simple colon.
var d = new Date('2018-02-28 :'); Greetings.
It really is not less a day , but less 4 hours: The Date class when the time is not passed, assumes that the time is 00:00:00 but in the hour use GMT 0000 , so on your machine, which has the time GMT-0400 , appears with 4 hours less.
My advice is to use the moment.js library to simplify, but another solution is to add the time: '2018-02-28 00:00:00'
The reason why the date comes out is because you need to put the whole date with hours minutes and seconds to convert it; like this: 2018-02-28 00:00:00
then your code would be like this
function myFunction() {
var d = new Date('2018-02-28 00:00:00');
var n = d.toString();
document.getElementById("demo").innerHTML = n;
}
greetings
