This fourth edition of the definitive reference to
JavaScript, a scripting language that can be embedded
directly in web pages, covers the latest version of the
language, JavaScript 1.5, as supported by Netscape 6 and
Internet Explorer 6. The book also provides complete
coverage of the W3C DOM standard (Level 1 and Level 2),
while retaining material on the legacy Level 0 DOM for
backward compatibility.
Availability
DOM Level 2 CSS
Synopsis
String item(unsigned long index);Arguments
index
The position of the desired CSS attribute name.
Returns
The name of the CSS attribute at index, or
the empty string if index is negative or
greater than or equal to the length property.
Description
The CSSStyleDeclaration interface represents a collection of CSS
style attributes and their values. This method allows you to query
the name of the CSS attribute by position and, in conjunction with
the length property, allows you to iterate through
the set of CSS attributes specified in this style declaration. Note
that the order of CSS attributes as returned by this method does not
necessarily correspond to the order in which they appear in the
document or style sheet source.
As an alternative to this item( ) method,
JavaScript allows you to simply treat a CSSStyleDeclaration object as
an array of CSS attribute names and use standard square-bracket array
syntax to obtain the attribute name at a specified position.
