Vue右键菜单

    rightShow(item) {
            this.isPersoncontextMenus = true;
            let menu = document.getElementById("msgRightMenu");
            var e = e || window.event;
            var marginWidths = 332;
            var marginHeight = 55;
            //鼠标点的坐标
            var oX = e.clientX - marginWidths;
            var oY = e.clientY - marginHeight;
            if(oX>423){
                oX = 423;
            }
            //菜单出现后的位置
            menu.style.display = "block";
            menu.style.left = oX + "px";
            menu.style.top = oY + "px";
            //阻止浏览器默认事件
            return false;//一般点击右键会出现浏览器默认的右键菜单，写了这句代码就可以阻止该默认事件
