在前端开发的时候，会用到“右键菜单”，如给div添加右键菜单等，

**示例：**

**代码如下：**

<!DOCTYPE html>
    <html>
     <head>
     <meta charset="UTF-8">
     <title></title>
     <script src="https://libs.baidu.com/jquery/1.11.3/jquery.min.js"></script>
      
     <style type="text/css">
    .s-move-content-outer{border:1px black solid;width:200px;height:200px;position:relative;outline:none;user-select:none;/*overflow:hidden;*/;}
    
    .vpopmenu{
        position:absolute;
        width:200px;
        border-radius:5px;
        background-color:rgba(13,78,146,0.9);
        border:rgb(13,78,146);
        z-index:9999;
        padding:2px;
        display:none;
    }
    .vpopmenu>div{
        padding:2px 2px 2px 30px;
        height:24px;
    }
    .vpopmenu > div:hover {
        background-color:rgba(245, 239, 89, 0.30);
    }
     </style>
     </head>
     <body>
     <div class="s-move-content-outer" tabIndex="1" >
        <div class="s-move-content-header">div1</div>
    	<div>内容1</div>
    </div>
    
    <div id="r_menu" class="vpopmenu">
        <div id="menu_create" onclick="createMenu();">新增</div>
        <div id="menu_copy" onclick="copyMenu();">页内复制</div>
    	<div id="menu_copy" onclick="delMenu();">删除</div>
    </div>
     </body>
     <script type="text/javascript">
    bindMenu();
    var menu = document.getElementById("r_menu");
    function bindMenu(){
    	//给所有class=s-move-content-outer的div都加上右键菜单
    	var $BIPanel = $("div[class='s-move-content-outer']").contextmenu(function(ev) {
    		 var oEvent = ev || event;
    		 //自定义的菜单显示
    		 menu.style.display = "block";
    		 //让自定义菜单随鼠标的箭头位置移动
    		 menu.style.left = oEvent.clientX + "px";
    		 menu.style.top = oEvent.clientY + "px";
    		 //return false阻止系统自带的菜单，
    		 //return false必须写在最后，否则自定义的右键菜单也不会出现
    		 return false;  
    		
    	});
    }
    
     //实现点击document，自定义菜单消失
     document.onclick = function() { 
    	menu.style.display = "none";
     }
     </script>
    </html>
