web 頁面防複製防拷貝
1、禁止另存為
<NOSCRIPT><IFRAME SRC=*.html></IFRAME></NOSCRIPT>
2、防止複製
oncopy="return false;" oncut="return false;"
3、防止選擇
<body onselectstart="return false">
4、徹底遮蔽滑鼠右鍵（好像不行）
oncontextmenu="window.event.returnvalue=false"
改為oncontextmenu="window.event.returnvalue=false" 可以
5、這段程式碼可以遮蔽右鍵，防複製等！（
<body 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=*></iframe></noscript>
6、防滑鼠右擊程式碼
<SCRIPT language=JavaScript>
function click(e) {
if (document.all) {
if (event.button==2||event.button==3) {
oncontextmenu=/'return false/';
}
}
if (document.layers) {
if (e.which == 3) {
oncontextmenu=/'return false/';
}
}
}
if (document.layers) {
document.captureEvents(Event.MOUSEDOWN);
}
document.onmousedown=click;
document.oncontextmenu = new Function(/"return false;/")
</SCRIPT>
