jquery - 鼠标悬停时无法将光标移动到子菜单

Question

我创建了一个带有子菜单的菜单，我唯一做的就是将子菜单放在 UL 之外(因为我别无选择)，问题是我无法将光标移动到子菜单，我试图检查是否与菜单和子菜单断开连接，但没有任何线索..

这是 JSFiddle工作演示

CSS

<style>
.nav{ float: right; margin: 22px 0 0; padding: 0; }
.nav ul{ float: right; margin: 0; padding: 0; font-size: 16px; }
.nav ul li{ float: left; margin: 0; padding: 0; /*position: relative;*/ display:block; padding:0 0 40px 0;}
.nav > ul > li > a{ color: #771521; padding:8px 15px 8px 15px; }
.nav ul li a:hover{text-decoration: underline;}

/*-----------Sub menu -----------*/
.submenu_willwid{position:absolute; width:100%; background:rgba(0,0,0,0.65); top:90px; padding:10px; box-sizing:border-box; display:none; z-index:101; min-height:195px; box-shadow:0px 7px 8px -4px rgba(0, 0, 0, 0.68); left:0;}
.menu_inner{width:100%; max-width:1200px; margin:0 auto;}
.submenu_col_full{width:20%; float:left;}
.submenu_col_full > h4{font-size:14px; color:#fff; text-transform:uppercase; font-weight:400; text-align:center; padding:0 0 10px 0;}
.submenu_col_full > h4 > a{color:#fff; text-decoration:none;}
.submenu_willwid:after, .submenu_willwid:before {bottom: 100%; left: 51.5%; border: solid transparent; content: " "; height: 0; width: 0; position: absolute; pointer-events: none;}
.submenu_willwid:after {border-color: rgba(0, 0, 0, 0);border-bottom-color: rgba(0, 0, 0, 0.68); border-width: 12px; margin-left: -12px;}
.submenu_willwid2:after, .submenu_willwid2:before {bottom: 100%; left: 59%; border: solid transparent; content: " "; height: 0; width: 0; position: absolute; pointer-events: none;}
.submenu_willwid2:after {border-color: rgba(0, 0, 0, 0);border-bottom-color: rgba(0, 0, 0, 0.68); border-width: 12px; margin-left: -12px;}

JQuery

$('#menu1').mouseover(function(){
  $('#submenu1').fadeIn();
});
$('#menu1').mouseleave(function(){
  $('#submenu1').fadeOut();
});

//Menu 2
$('#menu2').mouseover(function(){
  $('#submenu2').fadeIn();
});
$('#menu2').mouseleave(function(){
  $('#submenu2').fadeOut();
});

Answer 1

您的 mouseenter 和 mouseleave 事件代码应如下所述。这里的 stop() 方法用于停止运行动画。

//Menu 1
$('#menu1, #submenu1').mouseover(function(){
    $('#submenu1').stop().fadeIn();
});
$('#menu1, #submenu1').mouseleave(function(){
    $('#submenu1').stop().fadeOut();
});

//Menu 2
$('#menu2, #submenu2').mouseover(function(){
    $('#submenu2').stop().fadeIn();
});
$('#menu2, #submenu2').mouseleave(function(){
    $('#submenu2').stop().fadeOut();
});
