Ticket #10271 (closed bug: duplicate)
optionEl.attr('selected', false) messes up the DOM in WebKit browsers
|Reported by:||IgorMinar||Owned by:|
I have a piece of code that removes "selected" attribute from an option list and it stopped working when I upgraded from jQuery 1.4.2 to 1.6.4. After a plowing through my and jQuery code I found the bug in jQuery. Here is an annotated stack trace:
boolHook.set() at jquery.js:2445 <= "" value fails the test on line 2445 and jQuery adds the attribute back jQuery.extend.attr() at jquery.js:2286 <= we are back in attr(), but this time with "" as the value instead of false jQuery.extend.removeAttr() at jquery.js:2313 <= calls jQuery.attr(optionEl, "") boolHook.set() at jquery.js:2447 <= "selected" is gets boolHook, which calls removeAttr(optionEl, "selected") jQuery.extend.attr() at jquery.js:2286 jQuery.extend.access() at jquery.js:842 jQuery.fn.extend.attr() at jquery.js:1957 (anonymous function)() at widgets.js:891 <= I call optionEl.attr('selected', false) Scope.$digest() at Scope.js:355 Scope.$apply() at Scope.js:520 scope.$watch.optionGroups.() at widgets.js:768 <= my code is called jQuery.event.handle() at jquery.js:3001 jQuery.event.add.elemData.handle.eventHandle() at jquery.js:2635 <= an event fires
The end result is that the parent select element's value in WebKit browsers is set to "" even if there is another option with proper "selected" attribute. For some reason, FF is immune to this issue.
