jQuery ui.sortable._getParentOffset.top returns different values for chrome and ff

[amid2887]

jQueryui.sortable._getParentOffset.top returns different values for chrome and ff.

I have different values in that part of script in the _getParentOffset function:

po.top += this.scrollParent.scrollTop();

chrome and ff ( for exmaple ) returns different values..

And that produce some troubles with position of helper when I using ui.sortable.

For me now helps this changes to original code:

  po.top += this.scrollParent.offset().top;

Thanks for taking the time to contribute to the jQuery UI project! Please provide a complete reduced test case on jsFiddle to help us assess your ticket.

Additionally, be sure to test against the git version of both jQuery UI and jQuery to ensure the issue still exists. To get you started, use this boilerplate: ​http://jsfiddle.net/ZgAqH/ Open the link and click to "Fork" (in the top menu) to get started.

Also, please provide a description of how this affects users, not just a statement about the return value of an internal method. This will help anyone searching for duplicate tickets or anyone trying to verify and triage the bug.

Hmmm. When I am trying to create some test page I found the one alternative way to solve that problem.

Test cases are here: ​http://jsbin.com/ecepav/1 or ​http://jsfiddle.net/DRWHK/

How to see trouble: In the page you have some table with random info. Each TR of table can be sortable by jQueryUI.sortable(); You can to sort items and all looks fine, but if you scroll page more down and try to sort item you will see the more of scroll provide the most wrong sortable helper axisY position.

I'm trying to fix that like way I wrote upper, but now I found another way:

Problems dissapeared if ( in the examples ) we just remove

body { overflow-y: scroll }

OR

#wrap { position: relative }

. I understand it can be a solution for that but what I should to do if I need rules for body and #wrap ???

Platform: Win 7; Problem Browser: Google Chrome 23.0.1271.64 m;

Also if page has horizontal scroll - helper axisX position has too wrong positioning.

Duplicate of #5039.
@amid2887 From your test case this looks like a duplicate of #5039.
