David,

    Read up on the eval() function.  It can take a string and turn it into
the appropriate object reference, e.g.

var myPointer = eval("document.all.myDiv.style.color");

    Should be what you're looking for.

Cheers,

Peter

Subject: [Javascript] strings into variables

Hi, I'm trying to turn a string into a variable name.  In other words,
suppose I get input from a user, and want to convert that string into a name
of a variable and use it in a function.  The reason I have for doing this is
that the input I get from the user will be an actual preexisting variable
name in the script, but there are very many of these variables and I'd like
to refer to them without using switches.  I hope this was clear and please
tell me if you need clarification.

David Levy.
