NamedNodeMap: item() method

{{APIRef("DOM")}}

The item() method of the {{domxref("NamedNodeMap")}} interface returns the item in the map matching the index.

[!NOTE] This method is also called when you use the operator [] syntax. So, myMap[i] is equivalent to myMap.item(i) where i is a number.

Syntax

item(index)
[index]

Parameters

• index
  • : A number representing the index of the item you want to return.

Return value

An {{domxref("Attr")}} or null if the number is greater than or equal to the length of the map.

Example

<pre class="foo" id="bar" contenteditable></pre>

const pre = document.querySelector("pre");
const attrMap = pre.attributes;

pre.textContent = `The attribute map contains:
0: ${attrMap.item(0).name}
1: ${attrMap[1].name}
2: ${attrMap.item(2).name}`;
