网页禁止右击查看源代码JS（亲测可用）

　　将以下代码放入js文件即可：
//禁用右键
        window.onload = function(){
            //屏蔽键盘事件
            document.onkeydown = function (){
                var e = window.event || arguments[0];
                //F12
                if(e.keyCode == 123){
                    return false;
                //Ctrl+Shift+I
                }else if((e.ctrlKey) && (e.shiftKey) && (e.keyCode == 73)){
                    return false;
                //Shift+F10
                }else if((e.shiftKey) && (e.keyCode == 121)){
                    return false;
                //Ctrl+U
                }else if((e.ctrlKey) && (e.keyCode == 85)){
                    return false;
                }
            };
            //屏蔽鼠标右键
            document.oncontextmenu = function (){
                return false;
            }
        }
