Multiple Ternary Operators

rated 0 times [ 53] [ 1] / answers: 1 / hits: 141556 / 13 Years ago, thu, october 13, 2011, 12:00:00

I need a bit of syntax help with a ternary operator which will help me to put the correct marker icons on to my good map. I have three areas 0, 1 and 2 which have unique icons 0, 1 and 2.

I used to have just two areas so this ternary operator worked fine;

var icon = (area == 1) ? icon1 : icon0;

Now I need to add an additional third icon (icon2) for area2.

I've tried various methods but just can't seem to get it right.

The syntax would be:

var icon = (area == 1) ? icon1 : (area == 2) ? icon2 : icon0;

But this is starting to get complicated. You may well be better off just creating a function to do this work instead:

var icon = getIcon(area);



function getIcon(area) {

  if (area == 1) { 

    return icon1; 

  } else if (area == 2) { 

    return icon2; 

  }



  return icon0;

}
