The StylePropertyMapReadOnly.keys() method returns a new array iterator containing the keys for each item in StylePropertyMapReadOnly

Syntax

js

keys()

Parameters

None.

Return value

A new Array.

Examples

In this example we use the keys() method to be able to access the properties within our Element.computedStyleMap().

js

// get a button element
const buttonEl = document.querySelector("button");

// we can retrieve all computed styles with `computedStyleMap`
const allComputedStyles = buttonEl.computedStyleMap();

// keys returns an iterable list of properties
const props = allComputedStyles.keys();
console.log(props.next().value); // returns align-content
