[thelist] Using variables in DOM object names

[Joe Ngo]

The original code indicates the form fieldnames are in name
attributes, not id. As an alternative, not saying a better approach
but probably more backward-compatible:

        var fieldnames = new Array("firstname","lastname","city")
        for (var i=0; i<fieldnames.length; i++)
        {
               
window.opener.document.studentReg.elements[fieldnames[i]].value=document.studentSelect.elements[fieldnames[i]].value;
        }
