MutationEvent: attrName property

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.

The attrName read-only property of the MutationEvent interface returns a string with the name of the node affected by the DOMAttrModified event. It has no meaning for other events and is then set to the empty string ("").

Value

A string.

Examples

js
element.addEventListener(
  "DOMAttrModified",
  (event) => {
    console.log(event.attrName);
  },
  false,
);
