Question

我已经设置了一个带有javascript程序的bootstrap导航栏，可以在桌面屏幕上悬停，并可以点击手机和平板电脑屏幕。但我有一个问题，每当在桌面屏幕上，我点击任何导航栏任何按钮，它开始切换。所以我必须再次刷新页面才能使其正常工作。

$(document).ready(function(){
if($(window).width() < 768) {
    $('ul.dropdown-menu [data-toggle=dropdown]').on('click', function(event) {
        event.preventDefault();
        event.stopPropagation();
        $(this).parent().siblings().removeClass('open');
        $(this).parent().toggleClass('open');
    });
} else {
        $(function(){
            $('ul.nav li.dropdown').hover(function() {
                $(this).find('.dropdown-menu').stop(true, true).delay(200).fadeIn(500);
            }, function() {
                $(this).find('.dropdown-menu').stop(true, true).delay(200).fadeOut(500);
            });
        });
    }
});
