You can also check the following condition :

if($('#knd').css('visibility') === 'visible') {
    $("#wars").animate({
        opacity:'0'
    }); 
}

Suggested solution:

if($('#wars').css('opacity') === '0') {
    $("#wars").animate({
        opacity:'1'
    }); 
}

您可以使用.is（）以及：可见选择器：

if($('#knd').is(':visible')) {
    $("#wars").animate({
        opacity:'0'
    }); 
}

You can use .is(':visible') but you can use fadeToggle() or slideToggle() .

*Toggle() function automatically does what you're intending to do, with effects .
