Format date javascript

  • 772

I have the following string:

var fecha = "10-ene-2000";

I would like to format it as follows but still be a string:

var result = "2000-01-10 00:00:00"

How can I do it automatically?

    To do this you will first have to collect the date in format (YYYY-MM-DDTHH:MM:SSZ). Then convert it to string. Where does date come from? How are you picking it up?

    It doesn't help you to format "10-Jan-2000" (string) to "2000-01-10 00:00:00" (string), since a string does not contain the hour/minutes/seconds.

    I leave you a link to W3C by the way: Date Formats

    Because I understand that you want the hour/minutes/seconds to be correct right?

    EDIT: Edit according to comment:

    //Convertir el string a fecha para poder modificarlo
Date.parse(fecha);
//Poner el formato que quieres
dateFormat(fecha, "yyyy, mm, dd h:MM:ss");
//Volver a convertirlo a string
fecha.toString();

  2. If the issue of not having precision with the hour, minutes and seconds doesn't matter to you (that is, a string with 00:00:00 is generated) I think this solution can work for you.

    The first thing is to map the strings of the months as numbers (maybe there is a function that does it, but since I don't know it, I recommend this method that is more flexible).

    function convertirFecha(fecha){
    //Objeto javascript que vamos a utilizar como tabla hash para
    //La conversion de los meses a su representacion numerica

    let conversorMeses = {
        'ene' : '01',
        'feb' : '02',
        (...),
        'dic' : '12'
    };

    //Obtenemos el dia mes y año de la fecha original
    //Tal y como has puesto:
    //paramFecha[0] -> dia
    //paramFecha[1] -> mes
    //paramFecha[2] -> año

    let paramFecha = fecha.split("-");

    //Una vez tenemos los datos montamos el string resultante 
    let fechaRes = paramFecha[2] + "-" + conversorMeses[paramFecha[1]] + "-" + paramFecha[0] + " 00:00:00";

    return fechaRes;

}
