#11273 closed bug (cantfix)

Indeterminate checkboxes not matched with :checked selector in WebKit browsers

Reported by: lowbatteries Owned by:

Component: selector Version: 1.7.1

Blocked by: Blocking:


If a checkbox is checked, but then has the indeterminate property set, it will not be matched with the :checked selector (even though it is still checked, and would be posted with a form submission).

Reduced case here: http://jsfiddle.net/7TcKF/3/

This seems to boil down to .webkitMatchesSelector(':checked') which has the same incorrect behavior.

The issue does not appear in jQuery 1.2.6 or 1.3.2, but seems to have been introduced in 1.4.4 and onwards.

I confirmed the erronous behavior in Chrome 16, Chrome 18 (Canary), Safari 5.1.2, and WebKit nightly. This bug does not show up in Opera, IE6+, or Firefox.

May be related to this Chrome ticket, which from a rendering standpoint makes an indeterminate checkbox always appear to be unchecked: http://code.google.com/p/chromium/issues/detail?id=73233

The spec says indeterminate should only affect visual rendering so I agree this is a bug, but this seems like a Chrome qSA bug to me. We don't have a generalized way to work around it short of looking for ":checked" anywhere in the selector string and sending it down the Sizzle JavaScript path, which is a pretty cruel thing to do performance-wise for such a rare edge case.

This bug should be reported to Webkit, we don't have an effective way to fix it within jQuery.
