document.caretPositionFromPoint() #710

Open BenjaminAster opened 1 month ago

BenjaminAster commented 1 month ago

Description

The document.caretPositionFromPoint() method is currently not implemented in WebKit. Instead, WebKit implements the non-standard document.caretRangeFromPoint() method, which returns a Range instead of a CaretPosition. Note that Chromium also only recently added support for the standardized method.

Specification

https://drafts.csswg.org/cssom-view-1/#dom-document-caretpositionfrompoint

Additional Signals

WebKit bug: https://bugs.webkit.org/show_bug.cgi?id=172137

+1 to this proposal

I think this proposal should explicitly include supporting getting caret positions inside shadow DOM using the options parameter (https://drafts.csswg.org/cssom-view-1/#dictdef-caretpositionfrompointoptions). That has been a popular ask from web developers, but Chromium is currently the only engine that implements that part of the spec.

There appear to be basically no tests in WPT for this?

There are some here: https://github.com/web-platform-tests/wpt/blob/master/css/cssom/caretPositionFromPoint.html https://github.com/web-platform-tests/wpt/blob/master/shadow-dom/Document-caretPositionFromPoint.tentative.html
