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 the global document object.

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

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);
