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
js
delete(range)
Parameters
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:
js
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
