NamedNodeMap.getNamedItem()

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

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

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

const pre = document.getElementsByTagName("pre")[0];
const attrMap = pre.attributes;

let result = "The `test` attribute contains " + attrMap.getNamedItem("test").value + "\n";
if (attrMap["boum"]) {
  result += "And `boum` has been found.";
}
else {
  result += "And `boum` has not been found.";
}

pre.textContent = result;
