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:
<span class="a b c"></span>
Now the JavaScript:
let span = document.querySelector("span");
let classes = span.classList;
let item = classes.item(classes.length-1);
span.textContent = item;
The output looks like this:
