I have done several searches on the Internet, and I have found how to return two values in a function, and then how to access them, but what I need is to use a function to which a parameter passed and which in turn returns two values, I know this can be done in PHP, but I do not know how to do it in javascript . Let me explain myself a little better:

function ObtenerDate(valor){
  ....
  var valor_final = getHours();
  var date = getDate();

  return [valor_final , date ]
}

Later I call the GetDate () function

 for(i = 0; i<array.length; i++){
    var values = ObtenerDate();
    arreglo[i] = values[0](array[i]);  //ESTO NO ME FUNCIONA

}

The problem is when I call the GetDate function, accessing the position 0 or 1 I get data, but I do not know how to pass parameters that I need it for the function to work. I need to do for because in each cycle of for I call the function GetDate ()

EDIT (Adding information)

The variable array found in the for is where I store a set of dates in the UNIX EPOC type.

In the ObtenerDate() function is where I convert the date of array to the Y-m-d

format

In arreglo[i] is where I save the date already converted

Thanks in advance.

The error it throws is:

TypeError: values [0] is not a function

Which means that a call is being made to a method that does not exist and that you do here: values[0](array[i]); .

According to samples in your example, the function Date() returns values, not functions but you are accessing the value as if it were a function.

Are you trying to change the value of position 0 of values ? Then it should be like this:

values[0] = array[i];

Verify that your logic is OK since obviously values does not contain any reference to a function in position 0.

Greetings friend what you could do is create a function where you send as parameter a arreglo[] with all the data you need and in this function you enter as a response arrangement, so you would not have to use the for and you could have all the answers you need.

function Date[] ObtenerDate(String[] valor){
  date[] resp;
  resp[0]= getHours().;
  resp[1] = getDate();

  return resp
}
// luego lo llamarias algo asi por ejemplo
String[] valor;
valor[0] = "a";
Date[] arreglo = ObtenerDate(valor) ;
// no si es lo que necesitas pero podria ser una opcion

If you want to get two results or more than one function, instead of making an array, you should do, what is said in PHP, a indexed array but in javascript it is a object.

function ObtenerDate(valor) {
  ...
  var resultado = {
    valor_final: getHours(),
    date: getDate()
  };

  return resultado;
}

Then in the cycle for :

for (i = 0; i < array.length; i++) {
  var values = ObtenerDate('valorParametro');
  // asigno a la variable arreglo[i] el "valor_final" de la función
  arreglo[i] = values.valor_final;

  // asigno a la variable arreglo[i] el "date" de la función
  arreglo[i] = values.date;
}
