Is this the only way to do this?

[Confused]

Hi,

My background is more in C and PHP than javascript, but occasionally I
have to write small javascript functions. I recently needed to write
one where the parameter was the name of a form. The only way I could
find to assign the value of this form to a local variable was like
this:

function myFunction(formname)
{
var string = 'var f = document.' + formname;
eval(string);

This looks like a bit of a hack to me. Is there a better way to do
this?

Thanks.

Yes, simply use
var form = document.forms[formname];

Your exact question was answered yesterday morning. But ISTM that toy
may well, but not necessarily, find it easy enough to pass in a
reference to the form (essentially a pointer, though not described as
such in the language) rather than the name of the form as a string.
That is easy to use within your myfunction.
