DOMTokenList.entries()

The DOMTokenList.entries() method returns an iterator allowing you to go through all key/value pairs contained in this object. The values are DOMString objects, each representing a single token.

Syntax

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:

var span = document.querySelector("span");
var classes = span.classList;
var iterator = classes.entries();

for(var value of iterator) {
  span.textContent += value + ' ++ ';
}

The output looks like this:
