Question

I am trying to make a news system.
I have a table where each element is a function producing text.

I have a loop that checks whether news+number is a function or undefined.
If it is a function, then I push news+number to the array [number].

I am using eval, because i don’t know any other way to push the function name and the number to the array.

CODE:

var tablicaNewsow = [news1,news2]

function addNews ()
{
  var counterArray = 0;
  var fName = " ";
  fName = "news1";
  while (eval('typeof' + " " + fName) == "function")
  {
    //---------------sprawdzenie czy news istnieje----------
    fName = "news" + (counterArray+1);
    if (eval('typeof' + " " + fName) == "function")
    {
      //------------jest news
      tablicaNewsow.push(eval(fName+"()"));
      }
    else
    {
      //-----------nie ma newsa
      }
    counterArray++;
  }
}

NOTE:This is a code segment from my system, which pushes functions in the array.

Sorry for my bad English.

Answer 1

I think you’re looking for window["news"+number] (or similar). Any global variable can be accessed in this way.

Otherwise you could just use an array instead of indexing multiple variable names.
