tokenList.entries();
Return value
Returns an iterator

Examples
In the following example we retrieve the list of classes set on a
<span>
element as a DOMTokenList
using
Element.classList
. We when retrieve an iterator containing the key/value
pairs using entries()
, then iterate through each one using a
for...of
loop, writing them to 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 iterator = classes.entries();
for (let value of iterator) {
span.textContent += value + ' ++ ';
}
The output looks like this:
