{{APIRef("CSSOM")}}{{deprecated_header}}
The getCounterValue() method of the
{{domxref("CSSPrimitiveValue")}} interface is used to get the counter
value. If this CSS value doesn't contain a counter value, a {{domxref("DOMException")}}
is raised. Modification to the corresponding style property can be achieved using the
{{domxref("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.
getCounterValue()
None.
A {{domxref("Counter")}} object representing the counter value.
| 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). |
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It has been superseded by a modern, but incompatible, CSS Typed Object Model API that is now on the standard track.
