最牛的防复制代码1：（将此代码粘贴到body中可以有效防选中防复制和防鼠标右键）
<script type="text/javascript">document.body.oncontextmenu=document.body.ondragstart= document.body.onselectstart=document.body.onbeforecopy=function(){return false;};
document.body.onselect=document.body.oncopy=document.body.onmouseup=function(){document.selection.empty();};</script>
最牛的防复制代码2：（将此代码粘贴到body中可以有效防选中防复制和防鼠标右键）
<script language="JavaScript">
document.oncontextmenu=new Function("event.returnValue=false;");
document.onselectstart=new Function("event.returnValue=false;");
</script>
禁止查看网页源文件代码,插入网页即可。
<body leftmargin="2" topmargin="0" marginwidth="0" marginheight="0" oncontextmenu="return false" ondragstart="return false" onselectstart ="return false" onselect="document.selection.empty()" oncopy="document.selection.empty()" onbeforecopy="return false" onmouseup="document.selection.empty()">
<noscript><iframe src="/blog/*>";</iframe></noscript>
1.将彻底屏蔽鼠标右键
oncontextmenu="window.event.returnvalue=false"
<table border oncontextmenu=return(false)><td>no</table> //可用于Table
2.取消选取、防止复制
<body onselectstart="return false">
3.不准粘贴
onpaste="return false"
4.防止复制
oncopy="return false;" oncut="return false;"
5.防止被人frame
<SCRIPT LANGUAGE=javascript><!-- if (top.location != self.location)top.location=self.location; // --></SCRIPT>
6.网页将不能另存为
<noscript><iframe src="/blog/*.html>";</iframe></noscript>
7.改变连接是状态栏的显示内容
<a href="http://www.toyean.com" onMo ... ;window.status='输入连接状态栏显示内容’；return true">
8.禁止网页中目标对象被下载(如图片)
下面的代码将帮助你禁止网页中目标对象被下载：
<a href="javascript:void(0)" onMouseDown="alert('对不起!图片不能下载！')"><img src="图片地址" alt="" /></a>
9.页面禁止刷新完全，最好在pop出来的窗口里用,没工具栏的
<body onkeydown="KeyDown()" onbeforeunload="location=location"
oncontextmenu="event.returnValue=false">
<script language="Javascript"><!--
function KeyDown(){
if ((window.event.altKey)&&
((window.event.keyCode==37)||
(window.event.keyCode==39))){alert("请访问我的主页");
event.returnValue=false;
}
if ((event.keyCode==8)||(event.keyCode==116)){//屏蔽 F5 刷新键
event.keyCode=0;
event.returnValue=false;
}
if ((event.ctrlKey)&&(event.keyCode==78)){ //屏蔽 Ctrl+n
event.returnValue=false;
}
if ((event.shiftKey)&&(event.keyCode==121)){ //屏蔽 shift+F10
event.returnValue=false;
}
}
</script>
