javascript - :focus pseudo selector style not being removed when a new tab is opened , even though blur event is fired -


i working on nav menu contains external url links, there focus styles associated navigation menu , menu item gets background when focused. if item, anchor points external link, clicked, opens new tab , displays page represented external link. problem that, though new tab opened when user comes original tab, can still see background behind clicked nav menu item. there no :active styles associated menuitem.

i created example in js fiddle enumerate problem:
https://jsfiddle.net/bc5yu44v/2/

<body>   <a id="selectme" href="www.google.com" target="_blank" onblur="changetext()">clcik here</a>    </body>

here can see after new tab opened clicking anchor tag , anchor tag not loose :focus style, can see text changed , indicating onblur event fired.

can body point me on how remove :hover style?, possible using pseudo selector or can achieved writing js , toggling classes?. have restriction of not using jquery too. have tested in chrome , firefox only.

this happens because navigating away page causes page lose focus, takes focus away element within page may have been in focus @ time, why element's blur event fired.

once navigate page (or in case tab/window containing page), focus returned element in focus @ time, , if had onfocus event handler on element, fire well. element not lose focus permanently between page or window focus/blur events. similar behavior can observed switching windows, switching tabs, or opening , closing start if you're on windows.

you can force element lose own focus explicitly calling .blur() @ end of event handler, not onblur event handler onclick event handler instead, because otherwise element defocus when switch tabs, etc.
