The form object is a property and child of the document object. Each form is an ele-
ment of the forms[] array and each form has properties that correspond to the HTML
attributes of the form as well as properties that describe the form. As discussed previ-
ously, these properties might be objects in their own right; for example, the button prop-
erty of the form is also an object with its own properties. Some of the properties of the
form object are listed in Table 11.5 and methods are listed in Table 11.6. Properties of
the elements object are listed in Table 11.7.
