11.4.2 The Legacy DOM with Forms
The forms [] Array. Because the document contains forms, the form object is a prop-
erty of the document object . Every time you create a form in a given document, the
browser creates a unique form object and assigns it as an element of an array, called the
forms[] array. The index value of the array, starting at 0, corresponds to the order in
which the form occurs in the document; the first form is assigned to forms[0] , and each
successive form would get the next index value. When accessing a form from JavaScript,
the first form to appear in the page would be referred to as document.forms[0] and the
next form document.forms[1] , and so on. See Figure 11.11.
