Element.ariaColIndexText
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The ariaColIndexText
property of the Element
interface reflects the value of the aria-colindextext
attribute, which defines a human readable text alternative of aria-colindex.
Value
A string.
Examples
In this example the aria-colindex
attribute on the element with an ID of role-heading
is set to "Aria Role column". Using ariaColIndexText
we update the value to the string "New column name".
