在点击而不是在CSS上显示元素：悬停

Question

目前，我在CSS中使用:hover来显示.wrapper1元素中的嵌套列表。我想这样做是为了让它们在点击时打开而不是悬停。

这是我到目前为止所尝试的内容：

$(function() {
  // whenever we hover over a menu item that has a submenu
  $('li.parent').on('click', function() {
    var $menuItem = $(this),
        $submenuWrapper = $('> .wrapper', $menuItem);

    // grab the menu item's position relative to its positioned parent
    var menuItemPos = $menuItem.position();

    // place the submenu in the correct position relevant to the menu item
    $submenuWrapper.css({
      top: menuItemPos.top,
      left: menuItemPos.left + Math.round($menuItem.outerWidth() * 0.75)
    });
  });
});

下面是css，它可以影响显示所有子链接。

.wrapper1 li:hover > .wrapper1 {
  display: block;
}

Answer 1

$(document).ready(function(){ 

    $(".wrapper ul li").click(function(){
       //do what ever you want to do with li
    });
});

Answer 2

请看一下附件摘录。

jqyery代码和css也有一些变化。

$(function() {
  // whenever we hover over a menu item that has a submenu
  $('li.parent').on('click', function() {
       if($(this).children(".wrapper").attr('style')=='display: block;'){
          $(this).children(".wrapper").css('display','none');

    }else{
                  $(this).children(".wrapper").css('display','block');

      }
     
   });
  
  
});

.wrapper {
  position: relative;
}

ul {
  width: 200px;
  max-height: 250px;
  overflow-x: hidden;
  overflow-y: auto;
}

li {
  position: static;
}
li .wrapper {
  position: absolute;
  z-index: 10;
  display: none;
}
li:hover > .wrapper {
  //display: block;
  
}

li:

ul {
  margin: 1em;
  color: white;
  font-family: sans-serif;
  font-size: 16px;
}

li {
  padding: 1em;
}
li ul {
  margin: 0;
}
li .wrapper {
  cursor: auto;
}
li .wrapper li {
  padding: 0.5em;
}
li:nth-child(2n) {
  background: #0E8CE0;
}
li:nth-child(2n+1) {
  background: #0064B3;
}
li.parent {
  background: #00B99B;
  cursor: pointer;
}
