CSSRuleList |
an array of CSSRule objects |
Availability
DOM Level 2 CSS
Properties
- readonly unsigned long length
-
The number
of CSSRule objects in this CSSRuleList array.
Methods
- item( )
-
Returns the CSSRule object at the specified position. Instead of
explicitly calling this method, JavaScript allows you to simply treat
the CSSRuleList object as an array and to index it using standard
square-bracket array notation. If the specified index is too large,
this method returns null.
Description
This interface defines a read-only ordered list (i.e., an array) of
CSSRule objects. The length property specifies the
number of rules in the list, and the item( )
method allows you to retrieve the rule at a specified position. In
JavaScript, CSSRuleList objects behave like JavaScript arrays, and
you can query an element from the list using square-bracket array
notation instead of calling the item( ) method.
(Note, however, that you cannot assign new nodes into a CSSRuleList
using square brackets.)
