如何在单击其他父菜单项时关闭所有其他打开的子菜单？

标签： javascript jquery bootstrap-4

我正在使用此代码LINK。

当我点击Parent Menu之类的Services时，服务菜单的sub-menu将会打开，但当我点击其他菜单时，其他子菜单也会打开。 我希望当我点击其他子菜单时，之前的子菜单将关闭。 请为我提供解决方案。 谢谢

基本上你需要知道jQuery中not()的概念，这样你就可以隐藏除了点击之外的元素。这是工作示例。

＆＃13;
＆＃13; 
$('#menu-content').children("li").on('click', function(){
  $("li[data-toggle='collapse']").not(this).addClass('collapsed');
  $("li[data-toggle='collapse']").not(this).next('ul').removeClass('in');
  //alert('clicked');
});
＆＃13;

另一种适用于我的代码。

$(".submenu").not('.submenu-child').click(function()
{
    $(".submenu").not(this).find(".collapse").collapse('hide');

});

将 submenu 类应用于父菜单，将 submenu-child 类应用于子菜单。
