The HTMLFormControlsCollection.namedItem() method returns the RadioNodeList or the Element in the collection whose name or id match the specified name, or null if no node matches.

Note that this version of namedItem() hides the one inherited from HTMLCollection. Like that one, in JavaScript, using the array bracket syntax with a String, like collection["value"] is equivalent to collection.namedItem("value").

name

A string which will be used to match against the name or id attributes of the controls in this HTMLFormControlsCollection object.

• A RadioNodeList, Element, or null.

HTML

  <label for="notes">Notes:</label>

</form>

<div id="output"></div>

JavaScript

const form = document.querySelector("form");
const items = form.elements.namedItem("my-form-control");

const output = document.querySelector("#output");
const itemIDs = Array.from(items)
  .map((item) => `"${item.id}"`)
  .join(", ");
output.textContent = `My items: ${itemIDs}`;

Result

• HTMLCollection.namedItem that it replaces
