我为我的网页创建了一个汉堡包下拉菜单。但是我发现在点击其中一个链接后，下拉菜单没有关闭。我确实试图在网上找到解决方案，但没有一个能奏效。请帮忙！

Answer 1

因为您使用JavaScript＆amp;标记了问题。的jQuery ....

当你点击这样一个菜单项时，可以通过触发关闭按钮上的点击事件来实现：

$('.menu').on('click', 'li', function(){
    $('#menu-btn').trigger('click');
});

＆＃13;

＆＃13;

$('.menu').on('click', 'li', function(){
        $('#menu-btn').trigger('click');
    });
