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 HTMLBodyElement, 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". 154673 1 41194 xji 2009-10-14 16:38:37 -0700 Created attachment 41194 behavior difference between Document.caretRangeFromPoint in webkit and event.rangeOffset in FireFox 1. open the attached page 2. mouse click right before the first word "the" in the list, the container node and offset in the range returned from caretRangeFromPoint() is the text node "the first", and offset 0. 3. mouse click some where in the empty space around the bullet before "the first". caretRangeFromPoint() returns the same as the above. By comparison, open the above page in Firefox and repeat the above steps, you will see the node and offset returned from event.rangeParent/rangeOffset in FireFox are different if click on the text node and the element node. Does webkit have anyway to tell the difference? Seems that none of document.caretRangeFromPoint(), event.target, and document.elementFromPoint() shows any difference in the above 2 clicks. Should I apply for a new API for such differentiation? 39557 2009-09-14 11:19:39 -0700 2009-10-20 10:34:08 -0700 caretRangeFromPointInNonTextNode.html nonTextNode.html text/html 1092 xji PEhUTUw+CjxIRUFEPgo8VElUTEU+ZG9jdW1lbnQuY2FyZXRSYW5nZUZyb21Qb2ludCgpIE1ldGhv ZDwvVElUTEU+CjxzdHlsZT4KLnRhYi1jb250ZW50IHttYXJnaW4tbGVmdDoxODBweDt0ZXh0LWFs aWduOmNlbnRlcjt9Cgo8L3N0eWxlPgo8U0NSSVBUIExBTkdVQUdFPSJKYXZhU2NyaXB0Ij4KZnVu Y3Rpb24gc2hvd0VsZW1VbmRlcm5lYXRoV2l0aG91dFNjcm9sbCgpIHsKICAgIGRvY3VtZW50LmFs bC5teVNwYW4uaW5uZXJUZXh0ID0gIiI7CiAgICB2YXIgcmFuZ2UgPSBkb2N1bWVudC5jYXJldFJh bmdlRnJvbVBvaW50KGV2ZW50LmNsaWVudFgsIGV2ZW50LmNsaWVudFkpOwogICAgdmFyIG9mZnNl dCA9IDA7CiAgICBpZiAocmFuZ2UpCiAgICAgIG9mZnNldCA9IHJhbmdlLnN0YXJ0T2Zmc2V0Owog ICAgZWxzZSB7CiAgICAgIGFsZXJ0KCJyYW5nZSBpcyBudWxsIik7CiAgICAgIHJldHVybjsKICAg IH0KCiAgICB2YXIgY2hpbGQgPSBldmVudC50YXJnZXQuZmlyc3RDaGlsZDsKICAgIHJhbmdlID0g Y2hpbGQub3duZXJEb2N1bWVudC5jcmVhdGVSYW5nZSgpOwogICAgcmFuZ2Uuc2VsZWN0Tm9kZShj aGlsZCk7CiAgICB2YXIgc3RyID0gcmFuZ2UudG9TdHJpbmcoKTsKCiAgICBkb2N1bWVudC5hbGwu bXlTcGFuLmlubmVyVGV4dCA9ICJ4OiAiICsgZXZlbnQuY2xpZW50WCArICI7eTogIiArIGV2ZW50 LmNsaWVudFkgKyAiOyBzdHJpbmc6ICIgKyByYW5nZS50b1N0cmluZygpICsgIjsgICBvZmZzZXQg PSAiICsgb2Zmc2V0Owp9CmRvY3VtZW50Lm9uY2xpY2sgPSBzaG93RWxlbVVuZGVybmVhdGhXaXRo b3V0U2Nyb2xsOwo8L1NDUklQVD4KPC9IRUFEPgo8Qk9EWT4KPEgxIElEPSJoZWFkZXIiPmRvY3Vt ZW50LmNhcmV0UmFuZ2VGcm9tUG9pbnQoKSBNZXRob2Q8L0gxPgo8ZGl2IGNsYXNzPSJ0YWItY29u dGVudCI+CiAgPHA+dHlwZSBpbiB0aGUgYWRkcmVzcyBiYXIgYW5kIGdldCBzdWdnZXN0aW9ucyBm b3IgYm90aCBzZWFyY2ggYW5kIHdlYiAgcGFnZXM8L3A+CjxCUj48QlI+UmVzdWx0OiA8U1BBTiBJ RD0ibXlTcGFuIiBTVFlMRT0iZm9udC13ZWlnaHQ6Ym9sZCI+PC9TUEFOPiIuPC9QPgo8L0JPRFk+ CjwvSFRNTD4K 41194 2009-10-14 16:38:37 -0700 2009-10-14 16:38:37 -0700 behavior difference between Document.caretRangeFromPoint in webkit and event.rangeOffset in FireFox ff_elem.html text/html 726 xji PEhUTUw+CjxIRUFEPgo8VElUTEU+ZG9jdW1lbnQuZWxlbWVudEZyb21Qb2ludCgpIE1ldGhvZDwv VElUTEU+CjxTQ1JJUFQgTEFOR1VBR0U9IkphdmFTY3JpcHQiPgpmdW5jdGlvbiBzaG93RWxlbVVu ZGVybmVhdGgoZXZlbnQpIHsKICAgIGlmIChldmVudC5yYW5nZU9mZnNldCkgewogICAgICAgIHZh ciBub2RlID0gZXZlbnQucmFuZ2VQYXJlbnQ7CiAgICAgICAgdmFyIG9mZnNldCA9IGV2ZW50LnJh bmdlT2Zmc2V0OwogICAgICAgIGFsZXJ0KCJub2RlVHlwZTogIiArIG5vZGUubm9kZVR5cGUgKyAi OyBvZmZzZXQ6ICIgKyBvZmZzZXQpOwogICAgfSBlbHNlIGlmIChkb2N1bWVudC5jYXJldFJhbmdl RnJvbVBvaW50KSB7CiAgICAgICAgdmFyIHJhbmdlID0gZG9jdW1lbnQuY2FyZXRSYW5nZUZyb21Q b2ludChldmVudC5jbGllbnRYLCBldmVudC5jbGllbnRZKTsKICAgICAgICB2YXIgb2Zmc2V0ID0g cmFuZ2Uuc3RhcnRPZmZzZXQ7CiAgICAgICAgdmFyIG5vZGUgPSByYW5nZS5zdGFydENvbnRhaW5l cjsKICAgICAgICBhbGVydCgibm9kZVR5cGU6ICIgKyBub2RlLm5vZGVUeXBlICsgIjsgb2Zmc2V0 OiAiICsgb2Zmc2V0KTsKICAgIH0KfQpkb2N1bWVudC5vbmNsaWNrID0gc2hvd0VsZW1VbmRlcm5l YXRoOwo8L1NDUklQVD4KPC9IRUFEPgo8Qk9EWT4KPHVpPgo8bGk+dGhlIGZpcnN0PC9saT4KPGxp PnRoZSBzZWNvbmQ8L2xpPgo8L3VpPgo8L0JPRFk+CgoKCjwvSFRNTD4K
