CSSPrimitiveValue: getCounterValue() method
Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
The getCounterValue() method of the
CSSPrimitiveValue interface is used to get the counter
value. If this CSS value doesn't contain a counter value, a DOMException
is raised. Modification to the corresponding style property can be achieved using the
Counter interface.
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
getCounterValue()
Parameters
None.
Return value
A Counter object representing the counter value.
Exceptions
| Type | Description |
|---|---|
DOMException |
An INVALID_ACCESS_ERR is raised if the CSS value doesn't contain a Counter value (e.g. this is not CSS_COUNTER). |
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It has been superseded by a modern, but incompatible, CSS Typed Object Model API that is now on the standard track.
