网页不能复制
<body leftmargin="10" topmargin="0" marginheight="0" marginwidth="0" onmousemove='HideMenu()'
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=*></iframe></noscript>
鼠标完全被封锁：
在BODY里加上oncontextmenu="return false" ondragstart="return false" onselectstart="return false"
网页不能被另存为：
<noscript><iframe src=*.html></iframe></noscript> 要放在<head>之间
不准粘贴：onpaste="return false"
防止复制：oncopy="return false;"oncut="return false;"
