防止复制的js
-----------------------------------------------
<SCRIPT language=JavaScript1.2>
function disableselect(e){
return false}
function reEnable(){return true
}
file://if IE4+
document.onselectstart=new Function ("return false")
file://if NS6
if (window.sidebar){
document.onmousedown=disableselect
document.onclick=reEnable
}
</SCRIPT>
<SCRIPT language=JavaScript type=text/JavaScript>
<!--
function MM_reloadPage(init) {//reloads the window if Nav4 resized
if (init==true) with (navigator) {if ((appName=="Netscape")&&(parseInt(appVersion)==4)) {
document.MM_pgW=innerWidthdocument.MM_pgH=innerHeightonresize=MM_reloadPage}}
else if (innerWidth!=document.MM_pgW || innerHeight!=document.MM_pgH) location.reload()
}
MM_reloadPage(true)

防止下载的js

下面是防止右键的js:
--------------------------------------------------------
<script language="JavaScript">
<!--
if (window.Event)
document.captureEvents(Event.MOUSEUP)
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
}
}
}
document.oncontextmenu = nocontextmenu// for IE5+
document.onmousedown = norightclick// for all others
//-->
</script>
可以禁止用户右键，使用js操作禁止，参考以下代码
<script type="text/javascript">document.oncontextmenu=function(e){return false}
</script>
<body onselectstart="return false">
也可以直接禁止用户选中页面从而实现禁止复制的目的，可以在css里面操作禁止，参考以下代码
body {-webkit-touch-callout: none
-webkit-user-select: none
-khtml-user-select: none
-moz-user-select: none
-ms-user-select: none
user-select: none
}
以上两种方法都可实现禁止用户复制。
便捷的方式，可以通过Css禁用选取操作：<div unselectable="on" style="-moz-user-select:none-webkit-user-select:none" onselectstart="return false">
你选不了我,
unselectable: IE/Opera,
-moz-user-select: FireFox,
onselectstart: IE/Safari,
-webkit-user-select:Chrome
</div>
