javascript - 展开一个子菜单其他人应该自动隐藏在 jquery 中

Question

我正在尝试使用 CSS 和 JQuery 制作可扩展的 Accordion 菜单，我想制作一个垂直的 Accordion 菜单并在我单击其他主要链接时隐藏子菜单，有人可以帮我做这个吗。

$(function() {
	 
	$('.submenu-class li').has('.mainmenu-submenu, .mainmenu-submenu-sub, .mainmenu-submenu-sub-sub').prepend('<em class="mainmenu-click"><i class="arrowupdown"></i></em>');
	
	$('.submenu-class li').has('.megamenu').prepend('<em class="mainmenu-click"><i class="arrowupdown"></i></em>');
		
	$('.mainmenu-mobile').click(function(){
		$('.submenu-class').slideToggle('slow');
	});
	$('.mainmenu-click').click(function(){
	$(this).siblings('.mainmenu-submenu').slideToggle('slow');
	$(this).children('.mainmenu-arrow').toggleClass('mainmenu-rotate');
	$(this).siblings('.mainmenu-submenu-sub').slideToggle('slow');
	$(this).siblings('.mainmenu-submenu-sub-sub').slideToggle('slow');
	$(this).siblings('.megamenu').slideToggle('slow');
		
	});

});

这是更新的 fiddle

修改你的点击函数如下:

$('.mainmenu-click').click(function () {
    $('.mainmenu-submenu').hide();
    $(this).siblings('.mainmenu-submenu').show();
    $(this).children('.mainmenu-submenu').slideToggle('slow');
    $(this).children('.mainmenu-arrow').toggleClass('mainmenu-rotate');
    $(this).siblings('.mainmenu-submenu-sub').slideToggle('slow');
    $(this).siblings('.mainmenu-submenu-sub-sub').slideToggle('slow');
    $('.megamenu').hide();
    $(this).siblings('.megamenu').slideToggle('slow');
});

首先需要关闭所有已经展开的 Accordion ，然后显示事件的 Accordion 。希望这会有所帮助。
