HTML DOM forms attribute

formsA read-only attribute returns the embedded<FORM>List of elements.

The elements in the list are sorted in the order they appear in the source code.

If the document does not have a form, the returned list is empty and the length is zero.

Syntax:

document.forms

Example

var x = document.forms.length;

All browsers fully support the forms attribute:
