#div1{ width: 100px; height: 200px; border: 1px solid #333; position: absolute; display: none;}

<div id="div1"></div>

window.onload = function(){

        var oDiv = document.getElementById(‘div1‘);

        //自定义右键菜单
        document.oncontextmenu = function(ev){

            var ev = ev || event;

            oDiv.style.display = ‘block‘;    

            oDiv.style.left = ev.clientX + ‘px‘;
            oDiv.style.top = ev.clientY + ‘px‘;

            return false;                //阻止右键菜单的默认行为
        };

        document.onclick = function(){

            oDiv.style.display = ‘none‘;    //点击文档隐藏右键菜单
        };
    };
