javascript - 如果用户单击浏览器的上下文菜单，则会发生 Node.js 事件

Question

如果用户使用浏览器的上下文菜单并单击在新选项卡中打开链接选项，如何slideUp nav元素？

$('.title').on('click', function(){
  $('.nav').slideDown();
});

$('.nav').on('click', function(){
  $(this).slideUp();
});

.title{cursor:pointer;}
.nav{display:none;}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class='title'>MENU</div>
<div class='nav'>
<a href = 'https://google.com'>Google</a>
</div>

实际上，上下文菜单并没有给你100%接受的答案，你可以停止元素右键单击显示上下文菜单。您在此处显示自定义菜单代码，也许对您有帮助。链接:http://jsfiddle.net/6cqhsfvL/1/或以上代码

$('.title').on('click', function(){
	  $('.nav').slideDown();
	});

	$('.nav').on('click', function(){
		$(this).slideUp();
	});

	$('.nav a').on("mousedown",function(e){
		e.preventDefault();
		if(event.which==3){
			$('#item li a').attr('href', $(this).attr('href'));
		}
	});

	$('.nav a').bind("contextmenu",function(e){
	  	e.preventDefault();
		$("#cntnr").css("left",e.pageX);
		$("#cntnr").css("top",e.pageY);     
		$("#cntnr").fadeIn(200,startFocusOut());    
	});
    $("#items").on('click', 'a', function(event) {
	    event.stopPropagation();
	    $('.nav').slideUp();
	    $("#cntnr").hide(); 
	    window.open($(this).attr('href'), '_blank'  );
    });

	function startFocusOut(){
	  $(document).on("click",function(){
	  $("#cntnr").hide();        
	  $(document).off("click");
	  });
	}

.title{cursor:pointer;}
.nav{display:none;}

#items{
  list-style:none;
  margin:0px;
  margin-top:4px;
  padding-left:10px;
  padding-right:10px;
  padding-bottom:3px;
  font-size:17px;
  color: #333333;
}
#cntnr{
  display:none;
  position:fixed;
  border:1px solid #B2B2B2;
  width:150px;      background:#F9F9F9;
  box-shadow: 3px 3px 2px #E9E9E9;

}
li{
  padding: 3px;
  padding-left:10px;
}
#items :hover{

}
