用JAVA禁止复制网页内容
<Script Language=javascript>
function key(){
//if(event.shiftKey){
//window.close();}
//禁止shift
if(event.altKey){
alert(‘禁止CTRL-C复制本贴内容’);}
//禁止alt
if(event.ctrlKey){
alert(‘禁止CTRL-C复制本贴内容’);}
//禁止ctrl
return false;}
document.onkeydown=key;
if (window.Event)
document.captureEvents(Event.MOUSEUP);
//swordmaple javascript article.
//from www.xiaoxinglai.com
//function nocontextmenu(){
//event.cancelBubble = true
//event.returnValue = false;
//return false;}
function norightclick(e){
if (window.Event){
if (e.which == 2 || e.which == 3)
return false;}
else
if (event.button == 2 || event.button == 3){
event.cancelBubble = true
event.returnValue = false;
return false;}
}
function Click(){
alert(‘禁止右键粘贴本贴内容’);
window.event.returnValue=false;
}
document.oncontextmenu=Click;
</Script>

一个更简单的方法就是在<body>中加入如下的代码,这样鼠标的左右键都失效了.

topmargin=”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()”

1．禁止网页另存为：在<body>后面加入以下代码：
<noscript>
<iframe src=”*.htm”></iframe>
</noscript>
2．禁止网页内容复制．粘贴：在<body>中加入以下代码：
<body 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()”>
