That's incorrect. A form will function perfectly well with only name= attributes, and no ids, and it's quite possible for JavaScript to address theform elements using only the names (in fact, it's easier than via the ids as there's a short syntax for it!).

CSS and the DOM, however, use the ids as primary identifier, so use of either of those may demand the presence of ids.

Cheers!

True, you can access an input named "myInput" in a form named "myForm"
by simply writing:

document.myForm.myInput.value = "Hello!";

BUT... for CSS, it's also quite easy to reference something by name:

[name="myElement"]
{
color: blue;
font-size: 10pt;
}
