G'rrrr -- not this old chestnut again!
It only "screws up" your JavaScript if you don't write your JavaScript to
allow for it.
It's really very simple: *by* *definition* in JavaScript, the notation
a.b
is *identical* to
a["b"]
Thus, if you have a single checkbox named with name="system", then you can
access it in either of these ways:
document.form.system
document.form["system"]
By extension, if you have multiple checkboxes all named with
name="system[]", you can refer to them as:
document.form["system[]"][0]
document.form["system[]"][1]
document.form["system[]"][2]
etc...
I know this works because I've been using it for years (even before I
started programming with PHP!).
Cheers!
