jQuery Mobile Toggle会触发但不允许

Question

我想重建现有菜单（导航）以获得更好的移动性能。 当用户第一次单击菜单时，它会淡入但当用户单击具有子菜单的链接时，整个菜单会淡出（触发切换）。但相反，子菜单应该淡出

HTML标记：

<div class="menu-menue-1-container"><ul class="menu" id="menu-menue-1"><li class="menu-item menu-item-type-custom menu-item-object-custom menu-item-140" id="menu-item-140"  >

    $("#menu-menue-1").bind(jQuery.browser.mobile ? 'click' : 'tap', function() {


        $(this).find('li').fadeToggle(500);

        if (jQuery.browser.mobile === true) {

            console.log('mobile!');


        } else {

            console.log('desktop!');

            $(".menu-item-has-children").hover(function() {
                $(this).find('.sub-menu').toggle(500);
            });

        }

    });
    $(".menu-item-has-children").bind('tap', function(e) {
        e.preventDefault();
        e.stopPropagation();
        console.log('bis hierhin!');
        $(this).find('.sub-menu').toggle(1);
    });

那我做错了什么？提前thx抱歉我的坏事。
