ElementInternals.ariaColIndexText

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The ariaColIndexText property of the ElementInternals interface reflects the value of the aria-colindextext attribute, which defines a human readable text alternative of aria-colindex.

Note: Setting aria attributes on ElementInternals allows default semantics to be defined on a custom element. These may be overwritten by author-defined attributes, but ensure that default semantics are retained should the author delete those attributes, or fail to add them at all. For more information see the Accessibility Object Model explainer.

Value

A string.

Examples

In this example the value of ariaColIndexText is set to "Column name".

class CustomEl extends HTMLElement {
  constructor() {
    super();
    this.internals_ = this.attachInternals();
    this.internals_.ariaColIndexText = "Column name";
  }
  // …
}
