(JavaScript) What is the correct way to find a form?

What is the correct way to find a form? I have:

Code:

---

var formObj = eval('document.forms.' + formName)

---

But this was written some time back (over a year I believe), so was wondering if I needed to correct it.
Thanks,

forms is part of the DOM. So using...

Code:

---

syntax : document.forms(objectID/Name)...

document.forms('form1')...
document.forms(1)...

---

You'll also get away with using document.getElementById('form1') if the form has an id attribute and document.getElementsByName('form1') if name attribute

Shouldn't they be square brackets, or can you use standard ones?

it works with both but I [] is in the documentation

Oh right.

I changed to:

Code:

---

var formObj = eval(document.forms[formName]);

---

and it works great :)

Thanks,
Michael
