Forms and HTML validation

[yandr]

I am sure the answer is somewhere, but although I have searched for it I
couldn't find it.

I am doing form validation and I am checking each field using
document.FormNa me.FieldName.va lue
My problem is that I am using HTML 4 transitional and if I give a name to
the form (<form name="something ">) it will not validate. I also can't use
document.Forms[0].FieldName because I have multiple forms in each page.
The ID tag doesn't seem to work either (I mean just replace 'name' with
'id').

So, the question is how can I access the form and validate at the same time?
It would be best if someone can direct me to a tutorial that included
cross-browser compatibility (supporting DOM3 and previous versions).

Thank you very much in advance and sorry if this is stupid.

HTML 4.01 addressed that issue (in 1999):

document.forms["myFormName "].elements["myFieldNam e"].value

Use of ids for form referencing is not backwards compatible, but to get
a handle on the form:
document.getEle mentById("myFor mId")

Use the amended 4.01 DTD. A list of current DTDs can be found at:

Though the forms collection works just as well except, as you say, with
old browsers. Then only named forms can be accessed.
