Question

我有一个问题。是的，我不能添加div＆＃34;插入符号＆＃34;到我的下拉菜单，在只有孩子的菜单上。有我的代码

＆＃13;

$(document).ready(function(){
	if ($('.mobile-menu li:has(sub-menu)'))
	{	
  $('.mobile-menu li').parent('.ul').append('<div class=caret></div>');
	}
	else
	{
		alert('function is not working');
	}
					
				});

＆＃13;

/************************************************

.mobile-show{
dispay:block;
}
.mobile-menu{
position:fixed;
width:70%;
height:100%;
background:white;
z-index:1000;
}
.mobile-menu.sub-menu{

.mobile-menu ul{

    border-bottom:1px solid #000;
}

.caret:before {

    bottom:-25px;
    left:45%;
}

＆＃13;

<div class="mobile-menu">
      <ul class="mobile-menu-ul">
       <div class="caret"></div>
              <?php wp_nav_menu(array (                  
            'theme_location'=> 'new-menu',
			'container' => '', 
			'items_wrap' => '%3$s' 
                                                )); ?>

＆＃13;

我对此非常陌生，尤其是jQuery。这就是我的菜单现在的样子：http://prntscr.com/d6txgx菜单顶部是我想要的子元素时的样子在任何菜单中。目前底部是我的代码看起来像... 我很感激任何帮助!!谢谢！：）

如果它是正确的，您可以定位wordpress菜单类.caret并定位/************************************************ Mobile-Menu Style ************************************************/ .mobile-show{ dispay:block; } .mobile-menu{ position:fixed; width:70%; height:100%; background:white; z-index:1000; } .mobile-menu.sub-menu{ position:absolute; } .mobile-menu ul{ top:10.2%; color:black; position:relative; text-align:left; font-weight:bold; list-style: none; padding: 0; } .mobile-menu li a { display: block; position: relative; padding: 4% 0; border-bottom:1px solid black; } .mobile-menu > ul> li:hover > a, .mobile-menu > ul> li:hover > .sub-menu > li:hover > a, .mobile-menu > ul .sub-menu .sub-menu > li:hover > a{ background-color: #111; color: #fff; } .mobile-menu ul li.menu-item-has-children ul{ height:100%; width:100%; visibility: hidden; opacity: 0; transition: visibility 0s, opacity 0.5s linear; background:#fff; border:none; position:relative; } .mobile-menu ul li.menu-item-has-children:hover ul{ display:block; visibility: visible; opacity: 1; } .menu-item-has-children > a{ border-bottom:1px solid #000; } .menu-item-has-children > a:before { content:""; border-color:#FFF transparent transparent transparent; border-style:solid; border-width:12px; width:0; height:0; position:absolute; bottom:-24px; left:45%; z-index:1020; } .menu-item-has-children > a:after { content:""; border-color:#000 transparent transparent transparent; border-style:solid; border-width:12px; width:0; height:0; position:absolute; bottom:-25px; left:45%; } .mobile-menu ul li.menu-item-has-children:hover a:before{ border-color: transparent transparent #FFF transparent; bottom: 0; } .mobile-menu ul li.menu-item-has-children:hover a:after{ border-color: transparent transparent #000 transparent; bottom: 0; }上的所有css。

然后你不需要jQuery！

  <ul id="menu-top-menu" class="mobile-menu-ul">
