DOMTokenList: 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 DOMTokenList interface returns an item in the list, determined by its position in the list, its index.

Note: This method is equivalent as the bracket notation. So aList.item(i) is the same as aList[i].

Syntax

js
tokenList.item(index)

Parameters

index

A number representing the index of the item you want to return. If it isn't an integer, only the integer part is considered.

Return value

A string representing the returned item, or null if the number is greater than or equal to the length of the list.

Exceptions

TypeError

Thrown if the index cannot be converted to an integer.

Examples

In the following example we retrieve the list of classes set on a <span> element as a DOMTokenList using Element.classList. We then retrieve the last item in the list using item(tokenList.length - 1), and write it into the <span>'s Node.textContent.

First, the HTML:

html
<span class="a b c"></span>

Now the JavaScript:

js
const span = document.querySelector("span");
const classes = span.classList;
const item = classes.item(classes.length - 1);
span.textContent = item;

The output looks like this:
