For those interested, I made a little test to check out the performace of
eval.
It would appear that the speed of the following two calls in Internet
Explorer (5.5) are pratically identical:

  nTemp = document.myForm("myInput1").value ;

and

  nTemp = document.myForm.myInput1.value ;


However the call :

  nTemp = eval("document.myForm.myInput1.value") ;

in both Netscape (4.72) and IE took about twice as long. That said, both are
very quick (< milisecond on my machine) - so unless the javascript is
extremely intensive using the eval method should not pose a problem.


Cheers Imar for making the comment - I didn't think eval would be as great a
performance hit as that (hmm... I have some scripts to relook!).

For those interested the script used is copied below (you need a form with
two inputs).
