NamedNodeMap: item() method

The item() method of the 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

js

item(index)
[index]

Parameters

index

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

Return value

An Attr or null if the number is greater than or equal to the length of the map.

Example

html

<pre zero="test" one="test" two="test"></pre>

js

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}`;
