Drag and drop drop location

[TheEponymousBob]

Hi,

I'm trying to implement some drag and drop functionality in a Quill editor. I can see when I drag, say, a hyperlink over the editor that a drop-cursor appears at the nearest drop location within the text. But I haven't been able to find any way to get the screen coordinates of this cursor or relate that to a logical position within the document.

I can get the screen coordinates of the mouse cursor at drop, but that doesn't always match the drop-cursor location:

Is this something that anyone else has tried and/or succeeded at?

In case anyone else finds themselves needing this, there are a couple of nonstandard, browser-dependent ways to get this. Some browsers (not Firefox) offer Document.caretRangeFromPoint(), Firefox offers DragEvent.rangeParent/rangeOffset. I was able to use these in conjunction with Quill.find() and getIndex() to determine the drop location in Chrome/Edge/FF. Not sure about Safari (I can't currently test this), but it looks like it defines Document.caretRangeFromPoint().

Looks like there is also a Document.caretPositionFromPoint() that's not flagged as non-standard, but is definitely unsupported in Safari. Take your pick.
