Range: Range() constructor
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2017.
The Range() constructor returns a newly created
Range object whose start and end are offset 0 of the global document
object.
Syntax
js
new Range()
Parameters
None.
Examples
In this example we create a new range with the Range() constructor, and
set its beginning and end positions using the Range.setStartBefore() and
Range.setEndAfter() methods. We then select the range using
window.getSelection() and Selection.addRange().
HTML
html
<p>First paragraph.</p>
<p>Second paragraph.</p>
<p>Third paragraph.</p>
<p>Fourth paragraph.</p>
JavaScript
js
const paragraphs = document.querySelectorAll("p");
// Create new range
const range = new Range();
// Start range at second paragraph
range.setStartBefore(paragraphs[1]);
// End range at third paragraph
range.setEndAfter(paragraphs[2]);
// Get window selection
const selection = window.getSelection();
// Add range to window selection
selection.addRange(range);
