How can I compare two date strings with format dd/mm/yyyy in js?-CodePudding

I'm trying to compare a "Date" type of data with an "Any" type of data, but the comparison is not working.

I'm getting the date in this code:

var today = new Date();
var dd = String(today.getDate()).padStart(2, '0');
var mm = String(today.getMonth()   1).padStart(2, '0');
var yyyy = (today.getFullYear());
today = dd   '/'   mm   '/'   yyyy;

And I'm doing the comparison here:

for (const event of events) {
        if (event.fecha_fin >= today  && event.hora_fin > my_time) {
          console.log(event.fecha_fin > today)
          eventsWithLowestPrice.push(event.id_evento_fk)
          console.log(event.id_evento_fk)
        }
      }

The data type of event.fecha_fin is "Any".

I've tried to change both fecha_fin and today into "Number" data type but I don't really know how to do it.

I've tried changing the data type of "today" and "fecha_fin" to "Number" but I don't really know how to do it.

CodePudding user response：

Parse the strings as dates with

function stringToDate(str) {
  const [dd, mm, yyyy] = str.split('/');
  return new Date(yyyy, mm - 1, dd);
}

and compare the dates:

for (const event of events) {
  const date1 = stringToDate(event.fecha_fin);
  const date2 = stringToDate(today);
  if (date1 >= date2 && event.hora_fin > my_time) {
    console.log(date1 > date2)
    eventsWithLowestPrice.push(event.id_evento_fk)
    console.log(event.id_evento_fk)
  }
}

Example:

function stringToDate(str) {
  const [dd, mm, yyyy] = str.split('/');
  return new Date(yyyy, mm - 1, dd);
}

const events = [{fecha_fin: '01/01/2020', hora_fin: 2}];
const today = '02/02/2002';
const my_time = 1;

for (const event of events) {
  const date1 = stringToDate(event.fecha_fin);
  const date2 = stringToDate(today);
  if (date1 >= date2 && event.hora_fin > my_time) {
    console.log(date1 > date2)
    //eventsWithLowestPrice.push(event.id_evento_fk)
    console.log(event.id_evento_fk)
  }
}
