Synopsis
eval(string
)
Returns an object reference of the object described as a string in

can still use a for
loop to cycle through all
items by name if you let the eval()

convert the string representation of the names to object references:
for (var i = 1; i <=5; i++) { oneField = eval("document.forms[0].entry" + i) oneValue = oneField.value ... }
Returned Value
