我在使用 :not() 选择器/排除器时遇到问题。我正在做的是向打开的手风琴面板添加一个“.Activated”类（带有类“.panel”）。然后，当使用“.panel”类悬停所有元素时，我想运行一个函数。但是，有时会出现我不想在其上运行该函数的两个类“class="panel Activated"”的元素。
另外这里是我的一些相关代码：
function onOpenPanel(obj){
var slideR = obj.index + 1;
$('.panel:nth-child(' + slideR + ')').addClass('Activated');
}
$('.panel:not(.Activated)').hover(function(){
$(this).css('background-position','0px top');
},function(){
$(this).css('background-position','-41px top');
});
您会在网站上注意到，在打开的手风琴面板上，背景会跳跃 41 像素，因为我的 :not() 选择器没有选择面板也有 '.Activated' 类，因此不应受到影响.hover 功能。
