[thelist] Using variables in DOM object names

[Ryan Rushton]

I am setting values in one form (StudentReg) with values from another form
in a popup window (studentSelect).

The line for setting one form field looks like this:
window.opener.document.studentReg.ContactFirstName.value =
window.document.studentSelect.ContactFirstName.value;

Because there are many form fields to set, I would like to place them in
an array and loop over the array, but I don't know how to properly refer
to the objects when they have a variable within their name.  Here is my
NON-working code:

var fieldnames = new
Array("ContactFirstName","ContactLastName","Address","City","etc")
for (i=0; i<fieldnames.length; i++)
{
	eval('window.opener.document.studentReg.' +fieldnames[i] +'.value') =
eval('window.document.studentSelect.' +fieldnames[i] +'.value');
}

Any help with this would be greatly appreciated!
