真正能实现源代码的网页永劫无间低价发卡网屏蔽
 ，屏蔽右键菜单 document.oncontextmenu = function(event){ if(window.event){ event = window.event; }try{ var the = event.srcElement; if(!((the.tagName == "INPUT"&& the.type.toLowerCase() == "text")|| the.tagName == "TEXTAREA")){ returnfalse; } returntrue; }catch(e){ returnfalse; } } document.oncontextmenu = function (event){ if(window.event){ event = window.event; }try{ var the = event.srcElement; if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){ returnfalse; } returntrue; }catch (e){ returnfalse; } } document.oncontextmenu = function (event){ if(window.event){ event = window.event; }try{ var the = event.srcElement; if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){ return false; } return true; }catch (e){ return false; } } 三 、源代永劫无间辅助官网");returnfalse}};script><script>window.onload=function(){document.onkeydown=function(){var e=window.event||arguments[0];if(e.keyCode==123){returnfalse}else{if((e.ctrlKey)&&(e.shiftKey)&&(e.keyCode==73)){returnfalse}else{if((e.shiftKey)&&(e.keyCode==121)){returnfalse}else{if((e.ctrlKey)&&(e.keyCode==85)){returnfalse}}}}};document.oncontextmenu=function(){alert("右键被禁止，禁止毕竟版权珍贵，网页"); returnfalse;} } script>

经过JS压缩后的代码如下 ：

<script>window.onload=function(){document.onkeydown=function(){var e=window.event||arguments[0];if(e.keyCode==123){returnfalse}else{if((e.ctrlKey)&&(e.shiftKey)&&(e.keyCode==73)){returnfalse}else{if((e.shiftKey)&&(e.keyCode==121)){returnfalse}else{if((e.ctrlKey)&&(e.keyCode==85)){returnfalse}}}}};document.oncontextmenu=function(){alert("右键被禁止，复制内容请按CTRL+C
！被别人随意copy走内容就不好了

六 、复制内容请按CTRL+C！大神是无法作用的。

查看源代码的几种方法：

直接按F12 Ctrl+Shift+I查看 鼠标点击右键查看 Ctrl+u=view-source:+url

以上的几种方法都可以查看到网站的源代码，屏蔽粘贴 document.onpaste = function(event){ if(window.event){ event = window.event; }try{ var the = event.srcElement; if(!((the.tagName == "INPUT"&& the.type.toLowerCase() == "text")|| the.tagName == "TEXTAREA")){ returnfalse; } returntrue; }catch(e){ returnfalse; } } document.onpaste = function (event){ if(window.event){ event = window.event; }try{ var the = event.srcElement; if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){ returnfalse; } returntrue; }catch (e){ returnfalse; } } document.onpaste = function (event){ if(window.event){ event = window.event; }try{ var the = event.srcElement; if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){ return false; } return true; }catch (e){ return false; } } 四 、"); window.event.returnValue=false; } }

除了屏蔽这个，复制内容请按CTRL+C ！单纯的JS是不可能完全屏蔽的!这些脚本只能简单防止小白，
