HTMLLIElement: value property
The value property of the HTMLLIElement interface indicates the ordinal position of the list element inside a given <ol>. It can be smaller than 0. If the <li> element is not a child of an <ol> element, the property has no meaning.
It reflects the value attribute of the corresponding <li> element. If the <li> element does not have a value content attribute specified, then this property returns 0 by default even when the element may have a default serially-assigned ordinal value when rendered.
Value
An integer.
