Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The caretRangeFromPoint() method of the Document interface returns a Range object for the document fragment under the specified coordinates.

Syntax

var range = document.caretRangeFromPoint(float x, float y);

Parameters

x
A horizontal position within the current viewport.
y
A vertical position within the current viewport.

Returns

One of the following:

  • A Range.
  • Null, if x or y are negative, outside viewport, or there is no text entry node.

Example

Basic demo: When clicking in a paragraph insert a line break at the caret position:

HTML

<p>Lorem ipsum dolor sit amet, consetetur sadipscing elitr,

sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum.
Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet.</p>

JavaScript

function insertBreakAtPoint(e) {
  let range;
  let textNode;
  let offset;

  if (document.caretPositionFromPoint) {
    range = document.caretPositionFromPoint(e.clientX, e.clientY);
    textNode = range.offsetNode;
    offset = range.offset;    
  } else if (document.caretRangeFromPoint) {
    range = document.caretRangeFromPoint(e.clientX, e.clientY);
    textNode = range.startContainer;
    offset = range.startOffset;
  }
  // Only split TEXT_NODEs
  if (textNode && textNode.nodeType == 3) {
    let replacement = textNode.splitText(offset);
    let br = document.createElement('br');
    textNode.parentNode.insertBefore(br, replacement);
  }
}

let paragraphs = document.getElementsByTagName("p");
for (let i = 0; i < paragraphs.length; i++) {
  paragraphs[i].addEventListener('click', insertBreakAtPoint, false);
}
