我正在尝试创建下拉菜单，当单击“移动导航”按钮时，该菜单将打开和折叠。
请参阅此视频或网站作为预期行为的示例:
function mobileNav() {
$('.mobile-nav-toggle').on('click', function() {
var status = $(this).hasClass('is-open');
if (status) {
$('.mobile-nav-toggle, .mobile-nav').removeClass('is-open');
} else {
$('.mobile-nav-toggle, .mobile-nav').addClass('is-open');
}
});

- 您必须添加 jQuery 脚本的链接。
删除声明函数 mobileNav() { 及其关闭的小括号 }。
$('.mobile-nav-toggle').on('click', function() { var status = $(this).hasClass('is-open'); if (status) { $('.mobile-nav-toggle, .mobile-nav').removeClass('is-open'); } else { $('.mobile-nav-toggle, .mobile-nav').addClass('is-open'); } });
这是工作代码的示例 https://jsfiddle.net/efjz40ob/
