The property is read/write
for all objects except the following, for which it is read-only:
COMMENT, pages.
The property has no default value.
Remarks
The window.length property returns the number of frames contained in a window.
The comment.length property returns the number of characters in the object.
Although this property is read-only for most of the objects listed in the Applies To section objects, it is read/write for the areas collection (image maps), the options collection (select boxes), and the select object.
In all other cases, this property has read-only permission, which means you can retrieve, but cannot change, its current value.
The form.length property does not count input type=image elements. To access all elements contained in a form, use the children collection.
For Microsoft Windows CE only, this collection will always be empty.
In Microsoft Internet Explorer 6, This property now applies to the comment object.
