DOMTokenList.item

The item() method of the DOMTokenList interface returns an item in the list by its index.

Syntax

tokenList.item(index);

Parameters

index
A DOMString representing the index of the item you want to return.

Return value

A DOMString representing the returned item. It returns undefined if the number is greater than or equal to the length of the list.

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(length-1), and write it into the <span>'s Node.textContent.

First, the HTML:

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

Now the JavaScript:

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

The output looks like this:
