1. JS 禁止右键
<script type="text/javascript">
document.oncontextmenu=function(e){return false;}
</script>
<body onselectstart="return false">
......
2. CSS 禁止复制和选取
如果让整个页面都禁止选择
<style type="text/css">如果是局部
body {
-webkit-touch-callout: none;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
}
</style>
<style type="text/css"> .unselectable { -moz-user-select: -moz-none; -khtml-user-select: none; -webkit-user-select: none; /* Introduced in IE 10. See http://ie.microsoft.com/testdrive/HTML5/msUserSelect/ */ -ms-user-select: none; user-select: none; } </style>
3. 完整实例：
<style type="text/css"> body { -webkit-touch-callout: none; -webkit-user-select: none; -khtml-user-select: none; -moz-user-select: none; -ms-user-select: none; user-select: none; } </style> <script langauge="javascript"> document.oncontextmenu=function(e){return false;} </script> </head> <body onselectstart="return false"> ... ...
或者：
body{ -webkit-touch-callout: none; -webkit-user-select: none; -khtml-user-select: none; -moz-user-select: none; -ms-user-select: none; user-select: none; } function iEsc(){ return false; } function iRec(){ return true; } function DisableKeys() { if(event.ctrlKey || event.shiftKey || event.altKey) { window.event.returnValue=false; iEsc();} } document.ondragstart=iEsc; document.onkeydown=DisableKeys; document.oncontextmenu=iEsc; if (typeof document.onselectstart !="undefined") document.onselectstart=iEsc; else { document.onmousedown=iEsc; document.onmouseup=iRec; } function DisableRightClick(e) { if (window.Event){ if (e.which == 2 || e.which == 3) iEsc();} else if (event.button == 2 || event.button == 3) { event.cancelBubble = true event.returnValue = false; iEsc(); } }
其他常用的JS代码（js禁止的一些功能）
禁止查看源文件<script>
function clear(){
Source=document.body.firstChild.data;
document.open();
document.close();
document.title=”看不到源代码”;
document.body.innerHTML=Source;
}</script>
图片下载限制
<script language=”javascript”>
function Click(){
if(window.event.srcElement.tagName==”IMG”)
{
alert(‘图片直接右键’);
window.event.returnValue=false;
}
}
document.oncontextmenu=Click;
</script>
<pre name="code" class="html"><META HTTP-EQUIV=”imagetoolbar” CONTENT=”no”>插入图片时加入galleryimg属性
<img galleryimg=”no” src=””>禁止右键保存
把下面代码放在<head>和</head>之间
<SCRIPT LANGUAGE=java script>方式二：
function click() {
alert(‘对不起,您不能保存此图片,谢谢您的理解和支持!’) }
function click1() {
if (event.button==2) {alert(‘对不起,您不能保存此图片,谢谢您的理解和支持!’) }}
function CtrlKeyDown(){
if (event.ctrlKey) {alert(‘不当的拷贝将损害您的系统！’) }}
document.onkeydown=CtrlKeyDown;
document.onselectstart=click;
document.onmousedown=click1;
</SCRIPT>
在页面中加入如下js代码：原理：屏蔽右键
<script>页面禁止刷新完全
function document.onmousedown()
{
if(event.button==2||event.button==3)
{
alert( “右健被禁止 “)
return false
}
}
</script>
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>
</body
