Element.ariaColIndexText

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".
