html右键出现菜单

spruce 2022/07/12 效果很好

要在html里写script和style引入js/css代码!

html代码

<body oncontextmenu="showMenu(event)">
<div class="contextmenu" id="context">
    <ul>
        <li><a href="javascript:toDetail_();">详情</a></li>
        <li><a href="javascript:toTelecontrol_();">操作</a> </li>
		<li><a href="javascript:;">剪切</a></li>
		<li><a href="javascript:;">下载</a></li>
		<li><a href="javascript:;">上传</a></li>
    </ul>
</div>
</body>

css代码

    ul {
        list-style: none;
    }
    a {
        text-decoration: none;
        color: #333;
    }
    .contextmenu {
        width: 200px;
        border: 1px solid #999;
        box-shadow: 3px 3px 3px #ccc;
        background-color: #fff;
        position: absolute;
        top: 10px;
        left: 10px;
        display: none;
        z-index:9999999
    }
    .contextmenu li {
        height: 40px;
        line-height: 40px;
    }
    .contextmenu li a {
        display: block;
        padding: 0 30px;
    }
    .contextmenu li a:hover {
        background-color: #ccc;
        font-weight: bold;
        color: #fff;
    }

js代码

function showMenu(env){
	env.preventDefault();	    	
        //env 表示event事件
        // 兼容event事件写法
        var e = env || window.event;
        // 获取菜单，让菜单显示出来
        var context = document.getElementById("context");
        context.style.display = "block";
        //  让菜单随着鼠标的移动而移动
        //  获取鼠标的坐标
        var x = e.clientX;
        var y = e.clientY;
        //  调整宽度和高度
        context.style.left =x+"px" //Math.min(w-202,x)+"px";
        context.style.top = y+"px" //Math.min(h-230,y)+"px";
	// return false可以关闭系统默认菜单
        return false;
};
	  // 当鼠标点击后关闭右键菜单
document.onclick = function(){
        closeMenu();
};
function closeMenu(){
	var contextmenu = document.getElementById("context");
	contextmenu.style.display = "none";
}
