DOMTokenList: entries() method
The entries() method of the DOMTokenList interface
returns an iterator allowing you
to go through all key/value pairs contained in this object. The values are
Arrays which have [key, value] pairs, each representing a single token.
Syntax
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:
const span = document.querySelector("span");
const classes = span.classList;
const iterator = classes.entries();
for (const value of iterator) {
span.textContent += `(${value})`;
}
The output looks like this:
