29217 2009-09-11 18:16:51 -0700 document.caretRangeFromPoint should take the scroll offset into account before hit testing 2009-09-14 11:21:17 -0700 1 1 1 Unclassified WebKit DOM 528+ (Nightly build) All OS X 10.5 RESOLVED FIXED P2 Normal --- 0 xji webkit-unassigned annevk jshin mjs sam xji oldest_to_newest 146851 0 39496 xji 2009-09-11 18:16:51 -0700 Created attachment 39496 caretRangeFromPointWithoutScroll.html There are 3 issues: 1. I think the offset in the returned range should be the character/caret offset relative to the whole element, not relative to the viewpoint. Please see the attached file caretRangeFromPointWithoutScroll.html for detailed explanation. 2. If I pass in event.clientX + document.body.scrollLeft and event.clientY + document.body.scrollTop as the x-axis and y-axis to caretRangeFromPoint(), there is a possibility that the range is null which should not. Please see attached file caretRangeFromPointWithScroll.html for detailed explanation. 3. In caretRangeFromPoint(), there is the following code: Node* node = result.innerNode(); if (!node) return 0; Since we do not check whether the 'node' is a Text related node, there is a possibility that a range is created even when the mouse is not pointed in the text area. Please open caretRangeFromPointInNonTextNode.html, click mouse right before the first word "type", in the range created by caretRangeFromPoint(), the node is the Text node, the start/end offset is 0. click mouse several characters ahead of word "type" (the empty space in the left of "type"), although the 'node' is a HTMLParagraphElement, but it has the same visible position as the above, and the range created is the same as above. Is this the correct behavior? I think my assumption is that this function converts mouse position to the character position within an element, so a null range should be returned if click the empty spaces ahead of word "type". 146852 1 39497 xji 2009-09-11 18:17:32 -0700 Created attachment 39497 caretRangeFromPointWithScroll.html 146855 2 39498 xji 2009-09-11 18:18:55 -0700 Created attachment 39498 caretRangeFromPointInNonTextNode.html 146904 3 sam 2009-09-12 01:06:04 -0700 (In reply to comment #0) > Created an attachment (id=39496) [details] > caretRangeFromPointWithoutScroll.html > > There are 3 issues: You should really file three bugs if you think there are three issues, one for each of these. I am going to repurpose this bug to represent the first two, since I believe they represent the same issue, that we don't take the scroll offset into account before hit testing (which is the behavior of our elementFromPoint implementation, on which this API is modeled. Our elementFromPoint seems to be /wrong/' in this regard [bug 29219]). 146905 4 39507 sam 2009-09-12 01:10:04 -0700 Created attachment 39507 patch 146907 5 39507 mjs 2009-09-12 01:13:52 -0700 Comment on attachment 39507 patch r=me 146910 6 sam 2009-09-12 01:20:07 -0700 Fix landed in r48333. 147123 7 xji 2009-09-14 11:21:17 -0700 Thanks for the fixing.
