switching variable names dynamically

[tyler jones]

I have a number of arrays in my script and a drop down menu for the person to choose an item. Based off of which item they choose, I need to loop through the array that has the same name as the value of the option they selected. So, for instance, I might have something like this.

function dowhatever(sBox)
{
  var ar1 = new Array(1,2,3);
  var ar2 = new Array(2,3,4);
  var selectedArray = sBox.options[sBox.selectedIndex].value;
  // how do I loop through the selected array here?
}

<select onChange = "dowhatever(this);">
<option value="ar1">ar1</option>
<option value="ar2">ar2</option
</select>

Thanks.

Nevermind.... eval() to the rescue
