<P>
Array of objects corresponding to named forms (<TT>&ltFORM NAME=""&gt</TT> tags) in source order.

<P>The <I>forms</I> array contains an entry for each form object in a document. For example, if a document contains three forms, these forms are reflected as <TT>document.forms[0]</TT>, <TT>document.forms[1]</TT>, and <TT>document.forms[2]</TT>.

<P>You can refer to a form's elements by using the <I>forms</I> array. For example, you would refer to a text object named <I>quantity</I> in the second form as:
<PRE>
document.forms[1].quantity
</PRE>
You would refer to the value property of this text object as:
<PRE>
document.forms[1].quantity.value
</PRE>

<P>To obtain the number of forms in a document, use the length property: <TT>document.forms.length</TT>.
