HighlightRegistry: set() method

The set() method of the HighlightRegistry interface adds or updates a Highlight object in the registry with the specified name.

HighlightRegistry is a Map-like object, so this is similar to using Map.set().

Syntax

set(name, highlight)

Parameters

name: The name of the Highlight object to add or update. The name must be a String.
highlight: The Highlight object to add or update. This must be a Highlight interface instance.

Return value

The HighlightRegistry object.

Examples

undefined

Using set()

const fooHighlight = new Highlight();
CSS.highlights.set("foo", fooHighlight);

Using set() with chaining

Since the set() method returns back the registry, you can chain the method call like below:

const fooHighlight = new Highlight();
const barHighlight = new Highlight();
const bazHighlight = new Highlight();

CSS.highlights
  .set("foo", fooHighlight)
  .set("bar", barHighlight)
  .set("baz", bazHighlight);
