NamedNodeMap: getNamedItem() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The getNamedItem() method of the NamedNodeMap interface returns the Attr corresponding to the given name, or null if there is no corresponding attribute.

Note: This method is also called when you use the operator [] syntax. So, myMap[str] is equivalent to myMap.getNamedItem(str) where str is a string.

Syntax

js
getNamedItem(name)
[name]

Parameters

name

A string with the name of the desired attribute.

Return value

An Attr corresponding to the name given in parameter, or null if none has been found.

Example

html
<pre test="test"></pre>
js
const pre = document.querySelector("pre");
const attrMap = pre.attributes;
const value = attrMap.getNamedItem("test").value;
pre.textContent = `The 'test' attribute contains ${value}.
And 'foo' has ${attrMap["foo"] ? "been" : "not been"} found.`;
