防止页面F12或者右键查看源代码

在底层html页面引入相关js

<script language=JavaScript>

        $(document).bind("contextmenu", function () { return false; }); //禁止右键

                document.oncontextmenu = function () { return false; };

                document.onkeydown = function () {

                 if (window.event && window.event.keyCode == 123) {

                       event.keyCode = 0;

                       event.returnValue = false;

                       return false;

                   }

         }; //禁止F12

</script>
