It works in any scriptable browser as it originates from JavaScript 1.0 in 
Netscape Navigator 2.0 (which later was moved from the programming language 
to the Gecko DOM API, whereas Firefox is powered by Gecko) and the MSHTML 
DOM API in Internet Explorer 3.0, the so-called "DOM Level 0".

Possible, but that has nothing to do with what I commented on.  Which one 
could see had you quoted properly.

There is also an extra leading space in your From header field value, which 
you might want to remove.  Can one use your From header field value 
*unchanged* to contact you via e-mail?  If not, you want to fix that as 
well.

> Is this the old way

No, it is part of "the new way", but it is often used in spite of better 
approaches, and too often in a program.  The referencing I described above 
is both "old" ("DOM Level 0") and "new" (DOM Level 2 HTML, HTML5 Working 
Draft).

No.

The use of collections is better than shortcut referencing because the 
former is *both* backwards-compatible *and* standardized, and there is less 
chance for ambiguity (consider formRef.action etc. -- form control or not?). 

Shortcut references are only backwards-compatible and probably compatible 
for now.  They are neither specified by W3C DOM Level 2 HTML nor the most 
recent HTML5 Working Draft.
