CSSPrimitiveValue: getCounterValue() method

View on MDN ↗

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:

Syntax

getCounterValue()

Parameters

None.

Return value

A Counter object representing the counter value.

Exceptions

TypeDescription
DOMExceptionAn 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It has been superseded by a modern, but incompatible, CSS Typed Object Model API that is now on the standard track.
