NamedNodeMap: getNamedItem() method

{{APIRef("DOM")}}

The getNamedItem() method of the {{domxref("NamedNodeMap")}} interface returns the {{domxref("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

getNamedItem(name)
[name]

Parameters

• name
  • : A string with the name of the desired attribute.

Return value

An {{domxref("Attr")}} corresponding to the name given in parameter, or null if none has been found.

Example

<pre test="test"></pre>

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.`;
