Highlight: values() method
Baseline 2025Newly 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 values() method of the Highlight interface returns a new Iterator object that contains the values for each Range object in the Highlight object in insertion order.
Note:
The keys() method is an alias for this method. It behaves exactly the same and returns values of Highlight elements.
Highlight is a Set-like object, so this is similar to using Set.values().
Syntax
values()
Parameters
None.
Return value
A new iterator object containing each Range object in the given Highlight, in insertion order.
Examples
The following code snippet shows how to create a new Highlight object with three Range objects, and use the iterator returned by the values() method to log the three ranges:
const myHighlight = new Highlight();
myHighlight.add(new Range());
myHighlight.add(new Range());
myHighlight.add(new Range());
const iter = myHighlight.values();
for (value of iter) {
console.log(value); // Range
}
