Incorrect behaviour of $.removeAttr("selected")

[smartmaxim@…]

Calling $.removeAttr("selected") on the option that doesn't have "selected" attribute, changes the selection. Example:  http://jsfiddle.net/HHDpK/1/

Based on  http://stackoverflow.com/questions/8226702/jquery-removeattrselected-changes-selected-option

Thanks for submitting a ticket to the jQuery bug tracker. Please note that switching over to using .prop() for such cases (and .removeProp()) or the property removal should solve the problem you're running into. See here (jsFiddle from the answer on your SO post):  http://jsfiddle.net/HHDpK/3/.

Do I understand you correctly that $.removeAttr() is not backward compatible since 1.6? Sure I'm going to use $.prop() in a new code, but there is plenty already written.

Do NOT remove native properties with .removeProp. They cannot be recreated. Instead, we recommend:

$elems.prop('selected', false);
$elems.prop('selected', true);

Anyway, with the boolHook, this should be working. In removeAttr, we are setting attributes to empty string before removal. Unfortunately, the mere presence of a boolean attribute indicates true for the property and sets all other options' selected properties to false, and then removes it.

Just check : It caused by #9699 (setting first, then removal) .

Do not set boolean attributes to empty string on removal. Fixes #10870. +0 bytes compressed
