NamedNodeMap: item() 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 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}`;
