The values()
method of the DOMTokenList
interface returns an iterator
allowing developers to
go through all values contained in the DOMTokenList
. The individual values
are DOMString
objects.
Syntax
tokenList.values();
Parameters
None.
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 values
using values()
, then iterate through those values using a for ... of loop,
writing each one 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.values();
for(var value of iterator) {
span.textContent += value + ' ++ ';
}
The output looks like this:
