The read-only ownerElement property of the Attr interface returns the Element the attribute belongs to.


The Element the attribute belongs to, or null if the attribute is not linked to an element.


The following example displays the qualified name of the element of the two first elements, when we click on the appropriate button.

HTML Content

<svg xml:lang="en-US" class="struct" height="1" width="1">Click me</svg>
<label xml:lang="en-US" class="struct"></label>

  <button>Show value for &lt;svg&gt;</button>
  <button>Show value for &lt;label&gt;</button>

  Qualified name of the owner element of the attribute <code>xml:lang</code>:
  <output id="result">None.</output>

JavaScript Content

const elements = document.querySelectorAll(".struct");
const buttons = document.querySelectorAll("button");
const outputEl = document.querySelector("#result");

let i = 0;
for (const button of buttons) {
  const element = elements[i];
  button.addEventListener("click", () => {
    const attribute = element.attributes[0];
    outputEl.value = attribute.ownerElement.tagName.toLowerCase();
