Highlight: delete() method
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used 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
