在下面的小提琴我有一个右侧导航,它有一个子菜单,当用户在搜索栏中输入文字时,子菜单应该出现。 ATM。我必须将搜索框放在导航栏(.link-list
)之外,因为包含子菜单的元素出现在它上面因此无法输入。在最终的解决方案中,搜索字段应该在{{ 1}}。
如果您将鼠标悬停在子菜单上,我会希望它不可见,直到用户在搜索字段中输入任何内容为止。如果清除搜索字段或点击了.link-list
的链接,则应该关闭。
我需要做些什么来实现这一点,尝试.close-sub
,代码顺序,固定和绝对位置但没有成功。

你想要this之类的东西吗?
$('.js-search').on(

function() {
var $naviSub = $('.js-navi-sub');
var isShown = $naviSub.data('is-shown');
if (isShown !== Boolean($(this).val())) {
$naviSub.data('is-shown', !isShown)
.toggleClass('navi__sub_shown');
}
}
);
$('.js-close').on('click', function() {
var $naviSub = $('.js-navi-sub');
$naviSub.data('is-shown', false)
.removeClass('navi__sub_shown');
});
