Highlight: delete() method

Baseline 2025

Newly available

Since ⁨June 2025⁩, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

The delete() method of the Highlight interface removes a specified Range object from a Highlight object.

Highlight is a Set-like object, so this is similar to using Set.delete().

Syntax

delete(range)

Parameters

range: The Range object to remove from the Highlight.

Return value

Returns true if range was already in Highlight; otherwise false.

Examples

The code snippet below shows how to create a new highlight with two ranges, and then delete one of them:

const range1 = new Range();
const range2 = new Range();

const highlight = new Highlight(range1, range2);
console.log(highlight.size); // 2

highlight.delete(range1);
console.log(highlight.size); // 1
