CSSValueList: item() method
Deprecated
Avoid using this feature in new projects. The DOM level 2 CSS object model was excluded from the later CSS object model (CSSOM) specification. This feature may be a candidate for removal from web standards or browsers.
Consider using the following features instead: CSS object model.
Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.
The item() method of the CSSValueList
interface is used to retrieve a CSSValue by ordinal index.
The order in this collection represents the order of the values in the CSS style
property. If the index is greater than or equal to the number of values in the list,
this method returns null.
Note: This method was part of an attempt to create a typed CSS Object Model. This attempt has been abandoned, and most browsers do not implement it.
To achieve your purpose, you can use:
- the untyped CSS Object Model, widely supported, or
- the modern CSS Typed Object Model API, less supported and considered experimental.
Syntax
item(index)
Parameters
index-
An
unsigned longrepresenting the index of the CSS value within the collection.
Return value
A CSSValue object at the index position in the
CSSValueList, or null if that is not a valid index.
Specifications
This feature was originally defined in the DOM Style Level 2 specification, but has been dropped from any standardization effort since then.
It has been superseded by a modern, but incompatible, CSS Typed Object Model API that is now on the standard track.
