屏蔽f12审查

<script>
document.onkeydown = function () 
if (window.event && window.event.keyCode == 123) 
alert("F12被禁用");
event.keyCode = 0;
event.returnValue = false;

if (window.event && window.event.keyCode == 13) 
window.event.keyCode = 505;

if (window.event && window.event.keyCode == 8) 
alert(str + "\n请使用Del键进行字符的删除操作！");
window.event.returnValue = false;


</script>

　　

屏蔽右键菜单

<script>
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;



</script>

　　

屏蔽粘贴

<script>
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;


</script>

　　

屏蔽复制

<script>
document.oncopy = 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;


</script>

　　

屏蔽剪切

<script>
document.oncut = 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;

<script>

return false;

return true;
