如何使用左右箭头键在 bootstrap 导航栏中导航

Question

Bootstrap 3 菜单系统定义在下面的html中。如果打开菜单板，则忽略按左右箭头键。

如何像在常规 windows 菜单中一样强制向左箭头打开上一个菜单，并强制向右箭头打开下一个菜单板？在 jquery ui 菜单栏中左右箭头以这种方式工作。如何让它们也能在 bootstrap 导航栏中工作？

像这样的东西可以为您的代码提供帮助：

$(document).ready(function () {
    $('.dropdown').on('shown.bs.dropdown', function () {
        var $dd = $(this);
        $(document).on('keydown.dd', function (e) {
            if (e.which == 39) {
                $dd.next('.dropdown').find('.dropdown-toggle').focus().trigger('click');
            } else if (e.which == 37) {
                $dd.prev('.dropdown').find('.dropdown-toggle').focus().trigger('click');
            }
        });
    }).on('hide.bs.dropdown', function () {
        $(document).off('keydown.dd');
    });
});
