CSS标签悬停



是否有任何方法可以操纵此代码,以便一旦您将鼠标悬停在选项卡上,它将成为活动/默认/当前选项卡选择?

所以即使你向下滚动页面然后返回它也不会回到Tab1?

理想情况下,我只需要纯CSS:)

从你发布的小提琴(与jquery),用鼠标输入替换点击应该给你想要的小提琴与鼠标输入

$('.tabbox').on('mouseenter', function(){
   $('.tabbox').removeClass('active');
    $(this).addClass('active');
});

由于您是jquery新手,让我来解释一下它的作用。

$('.tabbox').on('mouseenter', function(){

选择所有类为'tabbox'的元素,并添加一个'mouseenter'事件处理程序,即下面的函数。所以每次'mouseenter'事件发生时,函数就会执行它的任务。

$('.tabbox').removeClass('active');
$(this).addClass('active');

当函数被调用时,它做的第一件事就是选择所有类为'tabbox'的元素,并从中移除类'active'。然后它将类'active'添加到'this', 'this'是对'mouseentered'对象的引用。
