Re: Can I use variables in Javascript object names?

In your example code, 'Day1' is a string and therefore does not have the .name property. If you are trying to access an element that has the name: 'dateDay1_year', then you can use eName (without .name). The document.getElementById() will find the correct element.

Thanks Neil, the explanation did the trick. I puzzled over the HTML for a while and finally saw that the HTML code contained names not IDs!!

Try :

function displayDate(eName) {
  var yy = 'date' + eName.name + "_year";
  var yyIndex = document.getElementById(yy).selectedIndex;
}


When I call displayDate('Day1') eName is 'Day1' and eName.name is
undefined. yy ends up being "dateUndefined_year"
